Joe Ambarian is a fourth year undergraduate majoring in Chemistry & Theater. Since June 2021, Joe has worked in the Davis Group under the mentorship of graduate student Samantha Horwitz; he uses X-ray crystallography to structurally characterize health-relevant proteins.
Outside of lab, Joe served on the inaugural cohort of the Department of Chemistry’s SAFE committee, working to advance several community engagement and DEI initiatives. Joe is also an RA on Emory’s campus, an intern with The Alchemist Letters, and a member of Emory’s Pottery Club.
Joe will continue his work with protein biochemistry and chemical biology in the fall as he pursues a PhD in Chemistry.
I am completely blown away by Joe’s ability to drive research forward. While he is a quick learner and careful in the lab, he doesn’t just blindly follow directions; he thinks deeply about what he is doing. This natural curiosity and inquisitiveness have helped him garner a great feel for when he needs to ask a question versus when to try and problem solve himself. Joe is independent, but not overly confident, which has earned him the trust of the graduate students and postdocs in my group. Furthermore, he is able to synthesize lab topics and coursework to clearly communicate his science.
Joe’s natural curiosity and enthusiasm for everything not only has made it easy to mentor him, but it’s even rubbed off on me during times when my motivation has been low, and I needed it most. There’s not a doubt in my mind that whatever he ends up doing, he will not only excel, but also bring insurmountable joy and comfort to the people around him while doing it.
I can easily envision a future where Joe is wrapping up work in the lab early to make it to the Broadway premiere of his award-winning original play that deftly explores the intersection of scientific knowledge and human experience.

Wenxiao is grateful for her experience at Emory and acknowledges the invaluable guidance and support provided by Dr. Khalid Salaita, Dr. Eri Saikawa, and her mentor in the Salaita Lab, Dr. Alisina Bazrafshan, throughout her fulfilling undergraduate academic journey.
I taught Wenxiao in her first and second years at Oxford, where she had the distinction of being in the "guinea pig" class—the first class of students to take the new courses in the Chemistry Unbound curriculum. Wenxiao took on this challenge with diligence and grace. It was a joy to be able to see Wenxiao's early development of laboratory skills, as well as the growth of her passion for learning science. When I wrote graduate school recommendation letters for her, I had no doubt that she would find a fantastic university and research group to join for her doctoral studies. I am so proud of her for achieving this well-earned recognition!
I don't want to say something generic - that she was hard working. But she really was! She was so driven and quietly focused. I am glad to see her continued success.

Sarah is a 2nd year PhD student at UCSD co-advised by Dr. Mark Herzik and Dr. Akif Tezcan. She is currently studying the structure and function of nitrogenase through both biochemical techniques as well as cryoEM. In her free time, she volunteers as a ChemPal mentor advising undergraduate chemistry students. She also works closely with the San Diego AWIS chapter on the PR committee.
At Emory, she worked in Dr. Brian Dyer's lab spectroscopically studying another exciting metalloenzyme: hydrogenase. In the lab, she developed and optimized a photocatalytic system to study light-driven electron bifurcation from a bifurcating hydrogenase.
Sarah is a wonderfully talented and fearless student who loves to take on big challenges. She worked on the important problem of electron bifurcation in my lab, which required her to learn a wide range of skills in bioinorganic and biophysical chemistry. This broad background equipped her for her graduate work to study the mechanism of nitrogenase enzyme turnover using cryo-electron microscopy techniques in the Tezcan and Herzik labs at UCSD. This is a very difficult problem, but Sarah is well prepared to make a big impact.

After his original lab left Emory, Eddy joined the Raj group and began to work on my project focused on investigating macrocyclic peptide cellular penetration. It was a completely different research topic than his stated interests and required learning a bunch of new techniques that he had no experience with. He took everything in stride, learned from the occasional mistakes, and was always a fun lab mate to work with. I am incredibly proud of Eddy and his achievements this year. He deserves all the support in the world and I am glad the NSF recognized his potential. I am excited to see where his academic career takes him and can't wait to call him Dr. Pineda.
Eddy Pineda is a fourth-year Chemistry major and Lusophone Studies minor from Dallas, TX. He has been an undergraduate researcher working under Dr. Jennifer Heemstra and Dr. Monika Raj. In the Heemstra group, Eddy attempted to develop a way to do live cell imaging of mRNA using an aptamer photoaffinity tag. In the Raj group, he is investigating the impact of aldehydes and 4-imidazolidinone on peptide cell permeability.
Outside of being in the lab, Eddy is a Woodruff Scholar who has worked on DEI initiatives through the SAFE committee while mentoring fellow first-generation, low-income students matriculating into Emory through STEM Pathways. He served as a teaching assistant for multiple organic chemistry courses and labs. Eddy is attending the University of Chicago for his graduate studies in Chemistry this fall, hoping to continue working in DEI and mentorship.
