Sara completed her Ph.D at Caltech in 2024, using GC-CIMS to study the kinetics and products of bimolecular peroxy radical reactions using both chamber experiments and field measurements. At UCLA, Sara is an NSF Postdoctoral Fellow studying the mechanism and atmospheric impact of the peroxy radical self-reaction, using a combination of IR action spectroscopy and atmospheric chamber experiments. When she's not in the lab, Sara likes to play bluegrass fiddle, go on hikes in the San Gabriel mountains, and play with her cat, Remus. 

Cooper received his BS in chemistry in 2023 at Cal Poly San Luis Obispo. His research interests involve exploring the complex gas and particle phase chemistry of Earth's atmosphere. With a better kinetic understanding of previously unexplored reaction pathways, he hopes to bolster atmospheric models and support efforts in combating climate change. In his free time, Cooper loves exploring new music, thrifting with his partner, and playing competitive Mario Kart! 

Rebeka completed her undergraduate degree at the University of Vermont in 2023 with a BS in Chemistry and English. Her research interests include the characterizing and off-gassing of smoke exposed materials, building new instrumentation to study gas partitioning dynamics, and partition modeling. In her free time, she enjoys reading, and going to Costco!

Rose graduated from Emory University in 2024 with a B.A. in Biochemistry and a minor in Environmental Sciences, working under Dr. Monika Raj. Newly ensconced in UCLA, her research focuses on electrical conductivity of aerosols in a joint venture with both the Kavner and Barber labs. Some of her interests include video games, dungeons and dragons, and going to conventions with her partner 

Keenan is originally from Santa Cruz, California. He graduated from Whitman college in 2025 with a BA in chemistry and in computer science, where he researched the surface chemistry of silver nanocrystals using machine learning to do high throughput autonomous liquid handling. Keenan is excited to work on creating a set of automated high-throughput environmental chambers capable of creating large datasets for machine learning in order to discover new mechanistic pathways of atmospheric oxidation. Outside of lab Keenan loves the beach, surfing, running, swimming, and playing beach volleyball. 

Tyler graduated from the University of Arizona in 2025 with a BS in Chemistry. He conducted research on membrane protein–lipid interactions through liquid chromatography–mass spectrometry experiments and developed a strong interest in analytical chemistry. He is now studying the gas-phase chemistry of peroxy radicals and is particularly excited to perform research on aerosol formation using the analytical instrumentation common in the atmospheric chemistry field. In his free time, he likes boogie boarding, riding his bike, doing yoga/pilates, listening to music, and cooking. 

Helen graduated from UC Riverside in 2025 with B.S. in Chemistry and a minor in statistics. Her research interests include utilizing infrared action spectroscopy and computational methods to study peroxy radical reactions. When not in lab, Helen loves to play her oboe, salsa dance, sing, crochet, bake, paint, and watch tv with her friends and cat. 

Daniel is a fourth-year undergraduate with a concentration in Physical Chemistry (UCLA 2026). His research focuses on isolating and discovering new pathways in the oxidation of aromatic hydrocarbons. Currently, he is investigating toluene's H-abstraction pathway. Outside of the lab, his hobbies include making song remixes, playing chess, and thinking of a third hobby. 

Chantal is a fourth year undergraduate chemistry (class of 2026) major with a minor in mathematics. She is currently working on a smoke exposure project. Outside of the lab, her hobbies include crocheting and playing Stardew Valley. 

Linus is an undergraduate physical chemistry major (UCLA 2026). Her current research interests are in high resolution spectroscopy, atmospheric reaction kinetics and climate advocacy, though she has previously worked in colloidal photophysics and crystal growth simulation.

Arthur is an undergraduate researcher in the class of 2026 studying biochemistry. His research interests include synthesis and modeling for atmospheric chamber experiments. In his free time, he enjoys drawing, playing video games, and cooking.
