Welcome to Lei Geng's Home Page.
I am a postdoctoral research associate at University of Washington, Department of Atmospheric Sciences. I am working in Prof. Becky Alexander's group. My work falls in a variety of topics related to atmospehric chemistry and climate feebacks, mainly using stable oxygen isotope tracers coupled with chemical transport models (regional or global) to understand the mechanisms of atmosphric oxidation chemistry, as a transfer of oxygen atoms involved in oxidation processes. I am also interested in using stable isotope tracers (e.g., nitrogen, sulfur) to understand the biogeochemiscal cycle of element of interest.
I have spent a lot of time working at UW IsoLab for isotopic composition analysis of environmental samples (mainly snow and ice core samples), and now I am focused on the use of chemical transport models (e.g., GEOS-Chem) for data interpretation.
