After receiving a B.A. in Chemistry from Willamette University in 1993, Wilson took a research assistant position at Los Alamos National Laboratory where he studied the chemistry of polar stratospheric ice clouds using nonlinear optics. During this time, he also received a M.A. degree in Liberal Arts from St. John’s College in Santa Fe, NM. He then earned a Ph.D. in Physical Chemistry in 2003 from the University of California, Berkeley. His doctoral work focused on probing liquid surfaces using synchrotron radiation at the Advanced Light Source (ALS), Lawrence Berkeley National Laboratory (LBNL). In 2003 he received a Fredrick Reines Distinguished Postdoctoral Fellowship from Los Alamos National Laboratory, where he began developing novel instrumentation for the sensitive detection of atmospheric particles. In 2004 he returned to LBNL as a limited term scientist at the Chemical Dynamics Beamline (ALS). Currently, he is a senior scientist and the Deputy Director of the Chemical Sciences Division at LBNL. In 2012 Wilson won an Early Career Award from the Office of Science (DOE), enabling his research group to focus on understanding the fundamental reaction mechanisms of organic molecules at liquid water interfaces. Wilson’s other research interests include soot formation chemistry, low temperature gas phase reactions in planetary atmospheres and the heterogeneous atmospheric chemistry of organic aerosols.

Ryan Reynolds

Graduate Student

I am a graduate student in physical chemistry at UC Berkeley interested in the kinetics of heterogeneous oxidation, especially in sub-micron organic particles with restricted diffusion of reactants. I completed my Bachelor’s degree in Chemistry with a minor in Mathematics at Biola University, where I studied the coupled oxidation and photochemistry of thin films of pesticides using ATR-FTIR spectroscopy. In the Wilson group, my research will include both experimental study of the oxidation of organic particles with VUV aerosol mass spectrometry and computer simulation of oxidation kinetics with Kinetiscope software, to understand how the mechanisms of oxidation change under varying conditions.

Liron Cohen

Graduate Student

I am a physical chemistry graduate student at UC Berkeley interested in probing the surface of aerosols to track chemical changes and pathways in environmentally relevant conditions. I have recently completed my Bachelor’s degree in chemistry at the University of Toronto working with Jamie Donaldson on coupling acoustic levitation and UV-Vis absorbance to measure the pH in-situ of ~1mm droplets. In the Wilson group, I will continue working on single-droplet systems using different trapping methods and spectroscopic techniques. I will examine the chemical make-up of droplets as they undergo reactions to gain fundamental insight into the processes governing heterogeneous reactions.

Alex Prophet

Graduate Student

I am currently a graduate student at UC Berkeley studying physical chemistry, having recently completed a bachelor’s degree in chemistry and mathematics at St. Olaf College in 2018. My research interests include the study of chemical reactions occurring at the liquid-air interface, and the behavior, composition, and reactivity of atmospheric aerosols. I would like to address these interests by using a combination of surface and bulk sensitive techniques such as X-ray photoelectron spectroscopy and Raman spectroscopy. In addition, the use of simulation and theoretical descriptions of interfacial dynamics will be critical in describing how observations of surface phenomena can be interpreted on both molecular and macroscopic scales.

Emily Brown

Graduate Student

I am a graduate student studying physical chemistry at UC Berkeley. I am interested in investigating the importance of the liquid-air interface to the kinetics of heterogeneous reactions in aerosol and droplet systems. As part of the Wilson group I will be able to study droplet systems experimentally in a quadruple electrodynamic trap, and also perform theoretical studies using Kinetiscope. I completed my bachelor’s degree in chemistry at Centre College in Kentucky in 2020 where I studied catalysts for the decomposition of lignin in an inorganic chemistry group led by Dr. Karin Young.

Anthony Garcia

Graduate Student

I am a physical chemistry graduate student at UC Berkeley researching the kinetics and dynamics of reactions occurring in microfluidic droplets. My research will utilize chip fabrication with soft lithography to develop chips capable of implementing unique operations and parameters to systems involving microfluidic droplets to study their effects in comparison to systems in bulk. I completed my Bachelor's degree in Chemistry at the University of California, Merced in 2020 where I studied reaction mechanisms in oxidative etching photoreactions with gold and platinum nanoparticles with Dr. Son Nguyen using UV-Vis spectroscopy. I would like to apply my interests in the study of reaction mechanisms in microfluidics with implementation of nanoparticles to better understand how nanoparticles can be used in reactions on the microscale.
