Journey to VEX Worlds Championships 2022

by Mayra Bibiano

My name is Mayra Bibiano, a B.S. in Aerospace Engineering – Astronautics major at Embry-Riddle, and from May 3rd to 5th I went with the VEX Robotics Gold team to compete at VEX Worlds 2022 in Dallas, Texas for the first time since 2018. Yet the team’s road to Worlds was a lot more complicated than you think, so how exactly did we get there?

Opening Ceremony at the VEX Worlds 2022 in the Dallas Convention Center.

If you don’t know, VEX Robotics is a club on the Prescott campus, with a Blue Team [ERAUB] and a Gold Team [ERAUG], that allows students from different majors and years to collaborate with one another to build and program two separate robots to compete with other teams in VRC (VEX Robotics Competitions). These competitions change year to year and this year, the competition was called Tipping Point. Two teams compete against one another to gather the most points on a 12-foot by 12-foot field. Each round is 2 minutes with a 45-second autonomous period and a 1-minute and 15-second driver-controlled period. Teams compete to score points by stacking rings onto mobile goals and by balancing these goals and/or the robot on a central platform. Teams can also earn bonus points from higher scores in the autonomous period. 

Our ERAUG team made two robots: the smallest robot, Jeef, was a robot that lifted mobile goals with pneumatics as well as getting onto the platform itself. Our bigger robot, Berky, was designed to get rings into the mobile goals that were around the field.

Once the spring semester rolled around, we were ready for our competition. Our first ever competition for the 2021-2022 school year was held on March 5 at the ERAU (Embry Riddle Aeronautical University) Prescott Campus. Our ERAU Gold Team won Tournament Champions, the Excellence Award and the Design Award. Under normal circumstances when seven teams attend our competition, we would have automatically gotten a spot at Worlds, but because we only had five teams in the competition we were not selected.

Members from left to right: Kevin Allyas, Tyson Boatman, Nikhil Dave, Francisco Zuniga, Piper Forcier (Gold team Build lead 2021-2022 year), Mayra Bibiano (Gold team Team lead 2021-2022 year), Amanda Davenport (Gold Team Programming/Notebook lead 2021-2022 year), Augustine [Austin] Barr, Dominic Stringer, Vishwas [Vish] Tanguria.

During that competition, our team attempted the Skills Challenge, where the two robots try to score as many points as possible without another team on the field. From this, we ended up ranking 33rd on the VEX U World Skills standing. From here we found out that if we ranked higher, we would be able to get a spot in Worlds. The team decided to practice getting a better skill score to secure our spot at Worlds and on March 15 we were given the opportunity to do another skills challenge and ended up improving by over 50 points. With that, we waited to see if we were given an invitation. Four days went by, and we got the best message from our president: “We are going to Worlds!!” The whole team was ecstatic because we did it without even knowing we could make it, but we did! After that day, we excitedly spent the whole month completely rebuilding our robots so that they would be Worlds ready.

The team walking around the Convention center to explore before matches began.

The first day of Worlds was just checking in, practicing and fixing anything just in case the robot moved a lot on the trip to Dallas. The next day was the first day of matches. That day was the most stressful and exciting day of the whole week. Our first three matches, losing two and winning one, really got us into a flow where we realized there were inconsistencies in our build and our program. From there we practiced nonstop. The only time we got a break was during lunch because the whole day was changing batteries, grabbing tools, grabbing robot plates, running to a practice field, running back to the match fields and so on. After that day, winning two out of six matches, we finally had time to breathe and think about how we could improve the next day.

That last day came, and I told everyone before we started our three matches, “No matter what happens today, let’s just have fun.” We won our first match of the day by 100 points and got off to a great start, but then ended up losing our last two matches. We may not have won most of our matches, but I know that those last couple of matches were the most fun we had the whole time. Not worrying about winning was such a good way to renew our energy and just have fun.

We ended up placing 30th of 37 teams in our division as well as ranking 25th in the skills standing. Looking back on our work this past year, and in years past for a lot of the team’s members, we are so happy with the experience we had at VEX Worlds. Our team gained a lot of problem-solving, time management and teamwork skills while working under pressure. With this, I know the team will be in good hands in the years to come with this experience.

I am currently a 4-year Aerospace Engineer student and graduating in December 2022 and this will be my 4th year in the VEX Robotics club and the 2021-2022 year I was the Team Lead. When I first joined the team I was interested in building robots because I had done it in middle school, but now it’s just a fun hobby and working with the team is always very fun. This club has allowed me to work on my team collaboration, organizational skills, leadership skills, and project management which will help me in the industry.  

If students decide to join the VEX Robotics club, we teach students how to build and program a robot. You don’t even have to be in a similar degree. Because of all the hard work the team has done throughout the years and the experience we have gained, we were able to go to Worlds. I know that in the coming years our team will be well cared for. I cannot express how proud I am of the team as well as how grateful we are for the experience.

Cybersecurity: A Growing Industry and Major at ERAU

Welcome back to the blog! Although a fairly new field, cybersecurity is a growing industry and major at ERAU Prescott. As a senior in the cyber department, I have been exposed to numerous different opportunities and experiences I have thoroughly enjoyed thus far. In my Riddle education, I have taken specialized courses in topics like Network Security, Database Security, Penetration Testing, and Operating Systems, to name a few. This program has opened doors where I can use these learned skills in real-world cyber scenarios, with internships at Northrop Grumman and the Army Cyber Futures Command, focusing on RMF compliance and vehicular network integrity respectively.  

This is an image of our distinguished Cyber Lab, a classroom every cyber student will step into at least once in their four years here. 

Participating in cyber organizations on campus has also provided an outlet in which I can practice and test my cyber skills in a recreational fashion with friends. I fondly recall my trip with the Cyber Defense Club to the RSA Conference in San Francisco in 2020, before COVID times. Not only did I get to see new cyber practices and innovations, but I also professionally networked and participated in workshops and CTFs. 

That being said, the cyber clubs are a great resource for networking, learning, and meeting other students of similar interests. When asked about their involvement, students shared their favorite experiences in their respective cyber organizations: 


William Noujaim

Ethical Hacking Club

William Noujaim, President of Embry-Riddle’s Ethical Hacking Club

What is your favorite part of leading the Ethical Hacking Club?

“As president of the Ethical Hacking Club, knowing that students will get to understand legal and ethical cybersecurity tools and techniques makes all the long hours of preparation worth it. Seeing students participate in competitions and succeed makes the club a success.”

What is the Ethical Hacking Club’s goal for its members?

“The Ethical Hacking Club is a community of individuals with one goal in mind, learning and performing ethical cybersecurity techniques through offensive and defensive practices. The Ethical Hacking Club’s motto is to encourage students to understand cybersecurity rules and practices. Knowing how to protect yourself online is the biggest takeaway from the EHC. Knowing what qualifies as legal and ethical practices in cybersecurity while having fun in competitions helps students of all majors learn best practices while understanding how to protect their personal data and understand how necessary cybersecurity is in the workforce.”

Mohammed Dalloul

Cyber Defense Club

Mohammed Dalloul, Vice President of Embry-Riddle’s Cyber Defense Club

What’s your favorite part of leading the Cyber Defense Club?

“My favorite part of leading Cyber Defense Club was planning and going on the club trip to the RSA conference in San Francisco, Ca, February 2020. We met a lot of industry leaders, built on teamwork, and friendships with fellow students during the trip. Overall, it was just one of the best experiences I’ve had in my college journey.” 

What is the Cyber Defense Club’s goal for its members?

“Cyber Defense Club is a cyber club on campus that aims to help and guide students and prepare them for a future in the job market as well as work on capture the flag competitions. We at CDC help our students with whatever they need to succeed we have guest speakers, competitions, trips to conferences, and informative PowerPoints.”

Hannah Ohm

Women in Cybersecurity

Hannah Ohm, President of the Women in Cybersecurity (WiCyS) Club

What’s your favorite part of leading the Women in Cybersecurity Club?

“During our meetings we try to engage our members in activities that will deepen their knowledge of cybersecurity. This semester we not only participated in NCL, but we also received licenses for CyberStart recently. Being able to teach them and see their excitement is one of the best experiences anyone can ever have.” 

What is the Women in Cybersecurity Club’s goal for its members?

“Our goal is to help support underrepresented students in cybersecurity and to foster a passion for cybersecurity within our members.”


As mentioned by these cyber student leaders, participating in said cyber clubs can help students understand how their class curriculum materializes in real-world environments. These organizations contribute to our technical knowledge and abilities, teaching cybersecurity topics not necessarily covered in the classroom. For example, to name a few, the WiCys team recently held an interactive Web Scraping exercise and is now working on a CyberAero project, diving into the crossover of cybersecurity and aerospace industries.

Hitting the Trail: Glassford Hill

On the cusp of the Prescott border into Prescott Valley, sits Glassford Hill and its corresponding Glassford Summit Trail. Although a fairly popular, multi-use path with much foot traffic, the hike isn’t overcrowded nor did I feel the uncomfortable pressure to walk faster. It is great trail to get outside and hike, not too strenuous and not too steep, rated at roughly 964 ft. of elevation. I appreciate this hike because I can enjoy nature whilst also being able to socialize with a hiking buddy without losing too much breathe.

Watch my hike on Embry-Riddle Prescott’s Instagram account.

As a 4.6 mile out-and-back trail, Glassford Summit Trail is a great morning hike where you can be sheltered in the cool shade until you reach the top of the hill to feel the warmth of the morning sun. It has a gradual incline with a few switchbacks constituting the trail. The climax of the hike offers generous views, overseeing all of Prescott Valley. 

Glassford Summit Trail is unique in its ability to educate on the history of Glassford Hill and the surrounding natural structures, with its numerous plaques and descriptions scattered throughout the trail. Targeting a different audience than Granite Mountain, Glassford Hill hosts many seating options throughout the journey for anyone wishing to rest or picnic. In this fashion, I recommend taking friends and family on this hike, for it offers a little bit of everything the casual hiker is looking for.  

The World’s Oldest Rodeo and 4th of July Celebration in Prescott

Arriving in Prescott, many college students experience a slower, traditional small-town vibe. Yet, when Christmas or patriotic holidays roll around, Prescott awakens. It is a festive Hallmark town, colored with cheer and décor. This 4th of July was no different. Drawing people from all over Arizona, Prescott was bustling with numerous events, like the World’s Oldest Rodeo, the 4th of July Parade, Northern Arizona’s Annual Tattoo Fest, and, of course, a fireworks show.

Taken in an alley, this gem of a Prescott mural was nicely hidden behind Whiskey Row.

To kick off the weekend, Prescott hosted the World’s Oldest Rodeo. Surprisingly, this was a culture shock like no other, a country culture shock if you will. I was not prepared, cowboy hat and boot-less. In awe, I watched as cowboy after cowboy competed in various horse-riding and animal lassoing events. Many times, I had to Google the competition I was watching, for I had never seen such a thing. But, like the large crowd of country folk in attendance, I was entertained and thoroughly enjoyed my time.

These friends (alumni Timmy Casnellie, alumni Ashley Carlson, student Keliz White) joined me in experiencing the rodeo life.

The annual 4th of July Parade processed down the streets of the downtown Courthouse Square, ultimately testing my parallel parking skills. Hundreds of Prescott locals showed up to support our veterans, lining the streets with red, white, and blue. The streets were overflowing with retro cars, local law enforcement, motorcycles, and tons of floats, from our own Golden Eagles Flight team’s float to a Democratic float, sporting a huge cutout poster of President Biden. If this puts into context how busy it was, I had to risk getting kicked by a flipping cheerleader just to cross the street for a coffee.

This is an example of the numerous tattoo shop booths that lined Tattoo Fest.

Unbeknownst to most, the Northern Arizona Annual Tattoo Fest was taking place at the Prescott Resort and Casino. Although daunting at first glance, the fest was a creative chaos; the air filled with the nonstop buzz of the needle as people were getting tattooed left and right. After spending many hours browsing the line of booths, I left the resort reflecting on all the life stories that were shared and souvenirs I collected. It was a welcoming environment, and I’m appreciative of this glimpse into the tattoo world.  

To complete the weekend, the fireworks show went off over Watson Lake. While the fireworks were grand and explosive, the fair-like activities prior were more enjoyable in my opinion. Since the pandemic, I have forgotten how the simple activity of picnicking with friends could be so fun. And, the grand finale of firework burst after firework burst made the trek back to the car in the dark worth it.

This image displays the start of the fireworks’ finale.

Overall, Prescott’s support and applaudable effort in celebrating this holiday weekend was a pleasure to partake in. Growing up in a city, I do miss the hustle and bustle of typical metropolitan life. Seeing the town rise to the challenge made me appreciate the community we are a part of, here, in Prescott, Arizona.

Hitting the Trail: Thumb Butte

No doubt, the town of Prescott is known for its numerous outdoor activities and hiking opportunities.

First sign entering the Thumb Butte trailhead, signifying the trail’s parking.

With such a well-known presence that ERAU even named dorms after it (T1 and T2), Thumb Butte is an ideal trail. Located in the Prescott National Forest, Thumb Butte Trail #33 is a moderate hike for people of all hiking backgrounds.

Thumb Butte trail information.

Hearing such appraisal in town, I too ventured out to the Thumb Butte. Once at the trailhead, I was instantly forced to make a decision that would greatly affect my hiking experience. Choosing to hike up the left or right route first, since it is a loop, would either be a more difficult steep climb or a nice gradual incline, respectively. Of course, representing the rebellious youth, I chose to start off with the difficult left side.

The two paths hikers must choose when starting the hike.
Hiking up the trail.

Honestly, the upwards half of the 2.5-mile loop was the ultimate thigh killer, paralleling the soreness one gets after leg day. The 700 ft elevation gain, fit into one mile of switchbacks, was no simple walk in the forest, pun intended. It was quite the struggle.

However, it was worth a quick sweat and soreness. The views on the climb up and opportunities to keep climbing higher were superb and greatly appreciated. Being a well-maintained concrete path, it was nice to see a chance to continue up an unbeaten path.

If you are considering hiking “Thumb Butt”, as I humorously call it, ensure you check the forecast prior. Living near the mountain, I have done this hike a couple times a month over the years and have made the mistake of hiking in wet and snowy climates; so, don’t follow my lead unless you enjoy involuntary sliding and sloshy shoes. Overall, as proven by my consistent return to the mountain, I recommend this trail for a day when you have the desire to hike but may not have the time to take on a longer adventure.

All About Classes

by Richard Santi

Embry-Riddle of course has exceptional flight training, a beautiful campus, and lots of fun activities available in and around the Prescott area. But what about the classes?

In high school I was not by any means the type of student that absolutely loved going to class. I wasn’t a bad student but can remember spending a lot of time watching the clock and waiting for the bell to ring.

Aeronautical Science students use flight simulation software to learn advanced jet systems, including programming a FMS computer like the one pictured in the top left of the screen.

Things changed after my first couple days at Embry-Riddle. Suddenly class became not only really interesting but incredibly fun! As an Aeronautical Science student with a Business Administration minor, I have gotten the chance to learn a lot of genuinely intriguing topics in the classroom taught by some absolutely brilliant professors who carry a wide range of industry experience. I went from looking at the clock waiting to leave, to looking at the clock not wanting to run out of time. In the Embry-Riddle classroom, I can say with certainty pretty much all of my professors have been kind and understanding, have had a strong desire to help students succeed. The best of all is that they come from a lot of diverse backgrounds with a ton of industry experience.

Our 1/2 scale model of the Wright Flyer hangs proudly in the lobby of our Academic Complex 1 which was completed in 2003, the centennial anniversary of the Wright Brothers’ pioneering flight.

The fact that a professor has experience in the industry is not something I thought too much about prior to coming to college, but I can say it is the principal thing that have made classes enjoyable for me. Getting to hear a presentation made by a retired military or airline pilot about the aircraft they flew and the experiences they had or listening to an interesting business lecture from someone who held a real-world management position at one of the world’s largest corporations are experiences that I have had and greatly cherish. It makes the classroom feel a thousand times more interesting.

Our new STEM Education Center features both an R-22 Helicopter given to us by universal Helicopters and a King Air propeller given to us by Raisbeck Engineering.

Lastly, one of the great parts of going to class in my mind is the manageable classroom sizes. The largest class I have ever had at Embry-Riddle had somewhere near 40 people in it, and I have only ever needed to take a couple of those. That is nothing like the 300-person lecture halls I had worried about when coming to college. Our average class size is around 25, but I can tell you that there are many classes you will have much smaller than that. I have had numerous labs and other classes that seated around 9 or 10 people. For me, this really was the way to learn. I like to be a part of the class, raising my hand often and having a professor who knows my name and respects me as a student, not just be a number in a large crowd.

College brings with it a lot of cool experiences. You will have a lot of fun at Embry-Riddle doing a lot of activities outside of the classroom. Like with any college, however, there will be a part of your day that will be spent in class. Why not attend college at a place where the classes are genuinely fun and interesting?

Halfway to Space

By Cooper Eastwood

This blog is an update to Cooper’s first blog: Aiming for Space with a Fully Reusable Rocket

Hi again! I am Cooper Eastwood, an Aeronautical Engineering sophomore and co-investigator of the Embry-Riddle Suborbital Reusable Vehicle. The whole world put itself on pause and everyone felt the effects. I know that at my home in Los Angeles many businesses and everyday workers have been forced inside due to the pandemic. Online learning, commerce, and communication became the new norm. I and many others have witnessed the whole world adapt and change in only a few months. Now almost a year later much has changed but the goal is always the same: to get to space cheaper and more often.

The Embry-Riddle Suborbital Reusable Vehicle (ERAU-SRV) team transitioned completely online during the summer period. Gaurav Nene and I stayed on task even in different parts of the country through video calls and scheduled meetings. Our small integrated team dynamic allowed us an easy transition as we can continue working diligently on the next steps of development whenever necessary. During this time, we submitted the lengthy and necessary documentation for unguided commercial suborbital vehicle launch approval at Spaceport America. We coordinated documentation with the FAA’s Office of Commercial Space Transportation (AST) and the New Mexico Spaceport Authority. Then in June 2020 we received the launch approval for a future date in 2021. We are taking our two-stage launch vehicle past the Karman line, or 100 kilometers, and to do so we need to launch from an FAA licensed facility. As New Mexico begins the process of allowing more frequent travel to their federal sites, the team will be at Spaceport America to observe the launch facilities and finally meet the ground support members.

To get the final funding we needed to finish the vehicle. The College of Engineering, the Undergraduate Research Institute, and Embry-Riddle’s Daytona Beach campus opened an opportunity for student projects to win grant funding by presenting in front of the Board of Alumni. Dr. Ron Madler, Dean of the College of Engineering, extended an invitation for us to further our research and break new ground with this brand-new alumni collaboration. We submitted a proposal to the board, bidding for a chance to present. This contained our preliminary design review, our FAA package, and the AIAA published technical report regarding our avionics. We qualified as one of the top three finalists and in under a week we made our presentation. Once the dust settled, we were awarded a grant to accelerate our work! With this new thrust of momentum and enough funding to purchase the rest of the booster stage, the next step in our engineering method was to verify our vehicle.

We required a launch test of our sustainer to accomplish six objectives: verify performance and our trajectory models, qualify the structural components, validate the recovery system, validate performance of telemetry, gain experience with pre-launch operations, and gain post-launch operations experience. After five days of integration we put the vehicle on the pad at Friends of Amateur Rocketry launch site in Mojave, California.

The ERAU-SRV sustainer takes flight!

On December 19th, 2020 at around 12:30 PM, the rocket was launched and experienced a recovery system failure at apogee which was addressed in a 35-page post-flight report. The sustainer surpassed its goal of 31,666 feet – exactly 6 miles. The vehicle was only partially recovered due to ballistic reentry, however we received two sets of flight data from our identical on-board computers. Every piece of the rocket was sifted from the sand, meticulously inspected, and documented. By finishing the in-depth report we completed five of our six objectives and proved that we could take the step forward on construction of the booster stage to launch at Spaceport America.

Recover and inspection of the rocket underway. We found parts to the GoPro, Spot Tracker, both AIM XTRA computers, as well as all the body components. Due to this inspection we found the root cause of the failure.

Immediately after our test we welcomed a new faculty advisor as well as a member of our team. Our previous faculty advisor Dr. Michael Fabian moved on to government research and Prof. Robert Gerrick, Mechanical Engineering Chair, took the role of our mentor. William Knoblauch, a Mechanical Engineering freshman, also became a member of our team by assisting in post-flight analysis and continuing testing research on flight critical hardware. We are in the process of accepting new members aiming to grow hands on experience with suborbital launch vehicles. As our vehicle and team grow, so do our hopes of surpassing our goals.

Gaurav (left) and Me (right) holding the sustainer right before placing it on the launch rail.

When the previous post left off, we were anticipating a trip to Portland, Oregon to attend the American Institute of Aeronautics and Astronautics (AIAA) Student Conference Region VI and present a 30-minute presentation on our avionics system at the conference. This was cancelled only a week before taking place in March 2020 and was postponed until the same time this year. Now after resubmitting the paper to a judge’s panel for review, it was accepted to the 2021 student conference at California State Long Beach and will be taking place in April.

Being a cross-discipline undergraduate research project gives us the opportunity to collaborate with a diverse group of engineers who can all contribute to space flight. As we expect many more space launches, the amount of experimental data gained per flight will be exponential. After a successful launch we will be calling on all students and as well as those considering enrolling at Embry-Riddle Prescott to form ideas, build hardware, and program experiments for the vehicle. These will all be taken to space, an environment that can be exclusively reached repeatedly only at Embry-Riddle. If you have a great idea and a goal, you really can get to space with the College of Engineering and the Undergraduate Research Institute’s backing.

The Trace Evidence Analysis of Makeup

by MaeLee DeVries

My name is MaeLee DeVries and I am a senior at Embry-Riddle Aeronautical University (ERAU) in Prescott, Arizona. I am majoring in Forensic Biology and I am interested in trace evidence, which is why I chose the research topic of trace evidence of makeup. We’ve all seen it on crime shows, there’s a piece of evidence that could not have been found, but somehow the investigators are always able to trace it back to the perpetrator in the end. While that is not wholly reality, it is not completely far from the truth either. Trace evidence can be very difficult to deal with because it is difficult to see, difficult to handle, and even more difficult to avoid cross contamination. However, if done properly, the analysis performed on trace evidence can corroborate stories and determine the truth. This is why I wanted to do this research because the more data there is, the stronger statistical values can be, which can create more conclusive evidence. Hopefully, this research helps contribute to a usable and searchable database for makeup to help investigators speed up investigation processes and be more objective in their investigations. After all, objectivity is one of the main goals of evidence-based research because it excludes bias and seeks the truth.

To be able to do this research, I had the privilege of receiving a Space Grant and being selected to be funded for an Ignite Undergraduate Research Project during the fall semester of 2020. The goal of this research was to support and develop a method for easily distinguishing the morphological and chemical features of various lipsticks and eyeshadow palette samples. There is a lot of data that still needs to be collected in trace evidence analysis of makeup research to fill the gap of information that exists; therefore, this research will demonstrate nondestructive analysis techniques that can help trace the evidence back to its source by providing more data that can be utilized in crime laboratories to assist in solving crimes. As the project leader and the only student on this project, my duties were to prepare the research samples, analyze the samples using a light microscope, Fourier-Transform Electron Microscopy (FTIR), and learn how to use the Scanning Electron Microscope in tandem with an Energy Dispersive Spectrometer (SEM/EDS) to analyze the potentially toxic chemicals within and individualistic characteristics of the different brands of makeup samples

Highly esteemed engineer, Dr. Lanning, teaching me how to use the SEM/EDS.

In this research my mentor, Dr. Teresa Eaton and I studied three different brands of eyeshadow and two different brands of lipstick. Originally, we were going to study six different brands of eyeshadow palettes; however, due to this being my last semester, time constraints did not allow me to study all of the samples I would have liked to; therefore, we studied palettes from Maybelline, Revlon, and Milani and a red lipstick sample and a pink lipstick sample each from Milani, and Wet n Wild. I did, however, run into some hiccups along the way, which is nothing new if you are familiar with research. First, preparing the samples took much longer than expected due to the meticulous cleaning and recleaning of materials to avoid cross contamination. When dealing with evidence, this is paramount. The second problem I ran into had to do with the SEM/EDS. While I was in the middle of viewing and analyzing my samples, the filament on the SEM/EDS burned out, putting my entire project to a halt. The filament allows for the visualization of the samples because that is where the electron beam originates, which without, the visualization is not possible. Obviously, I cannot research blindly; however, the kind Dr. Lanning (pictured above) came to my rescue, replacing the filament within hours. These roadblocks were impeding, but I got past them and was able to complete what I could of my research.

I analyzed a total of 37 samples viewed under the light microscope and analyzed using FTIR and 41 on the SEM/EDS, so a lot of samples were run, just not all of the samples I wanted to analyze. The techniques used were not invasive, other than the SEM/EDS and were able to discriminate between palettes, but not individual samples. FTIR was not invasive and quick, but only showed a fingerprint, while SEM/EDS was destructive, but showed the chemical composition and only used a very small amount of sample.

Optical Microscopy Images

FTIR Spectra and Data

Graph 1. Sub-sample 1b compared to TALC in an FTIR spectrum.
Graph 2. Sub-sample 2b compared to Silicon in an FTIR spectrum.

As you can see, Figure 1, 2, and 3 demonstrate the light microscopic view of a Milani eyeshadow sample, a Maybelline eyeshadow sample, and a Revlon eyeshadow sample, respectively. In my observations, I noted signature red-pink circular particles in nearly all of the Milani eyeshadow colors, which can help distinguish the samples from other palettes. In the Maybelline reflective eyeshadow sample glass-like and other reflective and metallic-like particles were noted, which were consistent with most of the shiny and glimmering samples. The Revlon eyeshadow was fine and fibrous, which was common throughout the more neutral and less glittery and shiny eyeshadows.

Graphs 1 and 2 are both FTIR spectra and show that there is a broad band at around 1000 in both sub-samples 1b and 2b. This was the same amongst nearly all of them, but other peaks helped differentiate between palettes based on what the chemical fingerprint was most likely related to. Most of the sub-samples from Sample 1 (Maybelline) were related to TALC, most of the sub-samples from Sample 2 (Revlon) were related to silicon, and most of the sub-samples from Sample 4 (Milani) were related to paraffin. This simple information is significant due to the differentiation it provides between palettes.

SEM/EDS Images and Data

Figure 4 shows the SEM image of eyeshadow sub-sample 2a by Revlon. The elemental composition is shown to the right demonstrating that there are two heavy metals that were not expected to be within this sample, Tc and Bi. Both are not toxic at low levels.

Figure 5 shows the SEM image of eyeshadow sub-sample 1i by Maybelline, which demonstrates expected heavy metals such as Fe, Cu, and Zn.

Figure 6 shows the SEM image of eyeshadow sub-sample 4e by Milani. Again, expected heavy metal content is observed as well as cylinders of carbon suspected to be some form of microplastics.

Figure 7 shows the SEM image of lipstick sample 16 by Wet n wild. Expected chemical composition is seen.

Finally, Figures 4, 5, 6, and 7 show the images from the SEM and the chemical composition from the EDS for eyeshadow and lipstick samples. Figure 6 shows that there are some heavier more toxic chemicals in the sample compared to the other samples, but these chemicals are not toxic to humans at very low quantities. There were no distinct chemical differences between the palettes other than Sample 2, which had Technetium and/or Bismuth in several of the samples. The SEM images were quite fascinating to look at, and while each sample did look different in its own way, it would be a subjective way to look at evidence and as I said earlier, that is not the goal of trace evidence.

This image shows me preparing the eyeshadow makeup samples and preventing cross contamination where possible.

My final results for this research project indicated that the chemical analysis techniques, FTIR and EDS, can potentially differentiate between palettes, but not individual sub-samples, while the optical microscopy techniques, light microscopy, and SEM, may be useful in differentiating between sub-samples in color and morphology. However, as I mentioned above, this process is much more subjective, and it is important to have objective methods of analysis in trace evidence. This analysis is not discriminatory enough by itself to differentiate between individual sub-samples, though it may be useful for differentiating between palettes. In the end, there was ample data gathered that demonstrated elemental, morphological, and spectroscopic properties of the samples for results and future analyses.

In conclusion, I hope this is not the end of this research because there is so much potential that this type of research has to assist crime laboratories in reaching the truth faster and more objectively. The opportunity I have had with this research project has yielded great experience and understanding for me in the future. Personally, I want to be a forensic DNA analyst, which must be an objective analysis technique, because the main goal is providing the truth. Not who we think did it. DNA analysis uses databases, which are crucial to conclusions; however, DNA cannot act alone in submission of evidence. Stories and other trace evidence must align in order for the truth to be found; therefore, other forms of trace evidence are vital and necessary. I love science and the potential it holds. After all, it is prepared to provide the truth, if we handle and analyze it properly.

A Great Start to Senior Year

Hello everyone! Summer has finally ended. This year, I felt so ready to get back into classes. It’s been about six months since I’ve been able to see friends and learn in a classroom. I moved back to Prescott two weeks ago to celebrate my friend Vee’s birthday.

Our freshman year, Vee and I lived in the same dorm! We met on the “Schools App” a few months before move-in and got to know each other. Though we don’t live together anymore, she’s become one of my closest friends. The people that I met my freshman year are all so important to me. We’ve grown and faced challenges together. Our friend Grace falls into that same category. She was a part of my orientation group, and we ended up getting along really well. Grace and Vee have been my family while away from home. We all made sure to socially distance before seeing each other in person. We’ve been keeping to pretty small social circles during the summer, so it was nice to be able to hang out with friends.

To celebrate Vee’s birthday, we visited Grace’s parents in Tubac. We spent a few relaxing days there swimming, looking after newly acquired plants, and making pizza. When we got back to Prescott, Vee planned a socially distanced birthday outing with a larger group of friends. We all brought blankets and masks and shared stories from summer.

Classes are quite a bit different than last year. About half the time, I meet with my class online, and when classes are in-person, we sit at every other chair. I’d be lying if I said it wasn’t going to be an odd semester, but I’m really looking forward to my classes. So far, I’m the most excited about my Capstone. Yesterday we were assigned our groups and projects. I’ll be working on Attitude Reaction Wheels. Our group is picking up where a capstone team from last year left off.

At Embry-Riddle in Prescott, an Engineers Capstone project takes two semesters. The first is focused on Preliminary Design and the second is Detail Design. The goal is to have a prototype built by the end of our senior year. It’s still hard for me to believe that I’ve started work on the biggest project of my four years at Embry-Riddle.

Over the last week, I’ve had so many people reach out about my first blog post! I’m happy to see that so many people seem to be excited about it. I’m looking forward to sharing my experiences on campus, but I’d also love to hear from you about what you’d like to hear about. Feel free to comment on this blog post with subjects you’d like me to write about!

The Road to Senior Year

by Bria Booth

Hello! My name is Bria Booth. I am an Aerospace Engineering and Systems Engineering student at Embry-Riddle’s Prescott Campus. I’m excited to say that I will be a student blogger during my senior year! While our fall semester will be quite a bit different than usual (social distancing, hybrid classrooms, and masks), I look forward to telling you all about it while sharing some of my favorite stories from the last three years.

Next year, I’ll be Member Development Vice President of Alpha Xi Delta (one of our campus’s sororities), Editor-in-Chief of the campus newspaper, and working on my Capstone project. Three things that I’ve been hoping for and looking forward to since my first year on campus. Even though the year is shaping up to be quite a bit different than I would have expected three years ago, I’m excited for everything that I have planned.

Now that I’m entering my last undergraduate fall semester I’m ready to get back to the classroom. I won’t lie, it’s been nice to have time to slow down and de-stress over the last few months. My summer has been slower than expected, but I wouldn’t call it un-eventful. I’m working on a virtual musical, fostering kittens, and taking online classes. I’ve done my best to stay busy and connected with friends and my community while staying safe.

I may be an engineering student, but in high school and middle school, I was a committed thespian. Whenever I’m home, I volunteer at the children’s theater that I grew up participating in. I’ve assistant directed, assistant choreographed, and stage-manged for several of their productions since I’ve left the stage. Their adult company is working on a virtual performance of In The Heights, which I’ve been lucky enough to be a part of. It’s always been important to me to find a creative outlet when I’m stressed, so this show couldn’t have come at a better time.

I started fostering kittens for spcaLA a few years ago, and it’s one of the most rewarding things I’ve ever done. I take anywhere between 1 and kittens and get to teach them to play and snuggle. Honestly, there are no downsides. I got the call from spcaLA that they had a kitten for me the day that I finished my spring finals. Since then, I’ve had 4 kittens come through my house this summer. Right now, I’m looking after a little black and white ball of fluff named Chai. He’s one of the sweetest cats I’ve ever met, and the perfect foster to finish the summer on.

I’ve had a lot of fun things to do this summer, but it was important to me that I was doing something productive while stuck at home. Through Embry-Riddle Worldwide, I’m taking Chemistry, Chemistry Lab, and Probability and Statistics online. When I added a Systems Engineering Minor to my track, my schedule got a bit cramped. I chose to take classes during a few of my summers so that I would still be able to graduate in four years. Embry-Riddle has made it so easy to do because of the options for online learning. My academic advisor helped me walk through my 4-year plan and map out what could be taken over summer to best free up time during the school year.

I am looking forward to next year, whatever challenges it may bring. It is so crazy to think that I am (hopefully) just two semesters away from graduation! I still can’t believe that I’ve been able to get through the last three years. It really doesn’t feel like it has been that long.

Thank you for reading, and I hope you’ll come back to this blog as I write about my senior year as an Aerospace Engineering student at Embry-Riddle Aeronautical University’s Prescott Campus!
