Elizabeth (Ellie) Wingen
Ellie is a fourth year undergraduate majoring in Biochemistry at UC Riverside and has developed a strong interest in organic chemistry research. Here she is running the Smith group’s Chemical Ionization Mass Spectrometer (CIMS) where she is comparing measurements of HOMs to those measured with Matrix Assisted Ionization in Vacuum (MAIV), also dubbed as Magic ionization by the Trimpin group at Wayne State University.
Katelyn Kiyoko Pacaud
Katelyn is a third-year Chemistry undergraduate at UCI specializing in Environmental Chemistry. In the lab, Katelyn is studying gas-particle interactions in the atmosphere using self-assembled monolayers on silica nanoparticles as a model for organic particles.
Cheyenne Begay
Cheyenne is in her third year majoring in Chemistry at UCI. She has been active in the Chemistry department as an undergrad learning assistant along with being a Science Olympiad test writer. In the lab, she analyzes the surface composition of organic particles using different mass spectrometry ionization techniques, such as Direct Analysis in Real Time (DART) and Matrix Assisted Ionization in Vacuum (MAIV).
Maryam Parvinian
Maryam is a third-year undergraduate Chemistry student at UCI specializing in Synthetic Chemistry. She has developed an interest in Organic and Environmental Chemistry research throughout the years. In the lab, she is currently studying the photolysis of neonicotinoids in the atmosphere and the oxidation of these atmospheric contaminants on solid substrates using attenuated total reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR).
— Post-doctoral scholar
Ryan Reynolds (not the actor!)
Ryan earned a B.S. in Chemistry from Biola University in 2019, with a minor in Mathematics. He received his Ph.D. in Physical Chemistry from UC Berkeley in 2024, where he used mass spectrometry to study reaction kinetics in organic aerosols in the Wilson Research Group at Lawrence Berkeley National Lab. He joined the Finlayson-Pitts lab as a postdoctoral scholar in 2024 and will be investigating gas-particle interactions using the Temperature Programmed Desorption (TPD)-Knudsen cell apparatus.

Mike J. Ezell
Mike received his M.A. degree in 1970 from California State University at Fullerton. From about 1980 until the present, he has worked in the Finlayson-Pitts labs on multiple projects and presently on reactive uptake of gas-phase amines on solid dicarboxylic acids.
Lisa M. Wingen, PhD
Lisa earned her B. S. in chemistry at California State University, Fullerton and her M.S. and Ph.D. in physical chemistry at UC Irvine in 1999. Her research projects have included almost everything under the sun — gas-phase chemistry of VOCs, photo-oxidation of sea salt aerosol, heterogeneous hydrolysis of nitrogen dioxide, composition and growth of laboratory-generated secondary organic aerosol, and others. She enjoys being able to take part in a variety of research projects with lots of instrumentation.
Weihong Wang, PhD
Veronique Perraud, PhD
Veronique earned a B.S. in Chemistry (with a minor in Natural Sciences) and a M.S. in Analytical Chemistry. She received her Ph.D. in Environmental Sciences from the University Aix-Marseille I in France in 2007. She has been working on many projects in the Finlayson-Pitts research group since April 2008 (link). She loves solving challenging analytical problems in the lab and blogging about how cool science can be! (Chem blog)
