Christopher M. Kenseth
Ph.D., Chemistry, Caltech
Christopher Kenseth is a NSF Atmospheric and Geospace Sciences Postdoctoral Fellow in the Department of Atmospheric Sciences at the University of Washington with Prof. Joel Thornton. He received his PhD in Chemistry from the California Institute of Technology with Profs. John Seinfeld, Paul Wennberg, and Brian Stoltz. His research uses laboratory experiments, advanced mass spectrometry, and organic synthesis to develop a molecular-level understanding of the chemical transformations that govern the formation, properties, and fate of organic aerosols in the atmosphere.
Carley Fredrickson
Ph.D., Atmospheric Sciences, University of Washington | website
I graduated with my PhD in 2024 where I studied reactive nitrogen emissions and chemistry from wildfires using both remote sensing platforms and models. Now working as an air quality consultant by day, I moonlight as a research scientist in Joel’s group evaluating HONO’s role within the Australian Black Summer wildfires using a regionally-refined global atmospheric chemistry model.
Previous Postdocs & Research Scientists
Ben H. Lee
Ph.D., Environmental Engineering and Science, Harvard University | website
Ben joined the Thornton group in the fall of 2012 as a NOAA C&GC postdoctoral fellow following his PhD work with Steve Wofsy and Bill Munger at Harvard. His research interests include oxidation mechanisms of biogenic terpenes, source and process attribution of SOA, and the impact of deforestation on the oxidative capacity of the atmosphere. He is a research scientist working with Joel Thornton and Abigail Swann.
In summer ’22 and winter ’23, Ben assisted graduate student Phil Rund in deploying an atmospheric pressure transverse IMR coupled to an iodide-adduct ionization LToF-MS to measure reactive chlorine and bromine species during the Boundary Layer Experiment on the Atmospheric Chemistry of Halogens (PI: Prof. Becky Alexander).
Olga Garmash
Ph.D., Atmospheric Sciences, University of Helsinki
Olga has joined the group as a postdoctoral researcher in 2022. In her research projects, she investigates the sources and composition of oxygenated organic compounds and the formation of secondary organic aerosol in different parts of the world: from remote oceans to urban environments. In addition, her research interests include autoxidation of aromatic compounds and chemistry of new particle formation. She has received PhD from University of Helsinki, Finland.
In summer 2022, Olga participated in AGENA field campaign and deployed high resolution mass spectrometer coupled with dual I-/Br- ionization scheme to detect oxygenated organic compounds, halogen species and other trace gases. Olga is also involved in instrument installation at the UW ASCENT site. In 2023, she will join AEROMMA campaign and conduct aerosol chemical composition measurements to understand the sources and evolution of organic aerosol within the polluted air outflow from New York City.
