Dr. Nichols is a postdoctoral associate who specializes in organic geochemistry and data science in the Department of Geosciences at Virginia Tech, working with Dr. Benjamin Gill and Dr. Rachel Reid. His research focuses on understanding biological signatures, specifically lipid biomarkers, in hypersaline environments. He utilizes these lipid biomarkers to make inferences about potential life on Mars (past and present). Additionally, he uses these same signatures in combination with stable isotopes to make reconstructions of paleohydroclimate from hypersaline environments.
Dr. Nichols' postdoctoral work continues to investigate lipid biosignatures in diverse hypersaline systems including hypersaline lakes of British Columbia, the Mojave Desert, and the Atacama Desert in tandem with machine learning to provide agnostic insight into the influence of biosignature production and preservation. Additionally, this data serves as a springboard to provide more information about organic carbon turnover in hypersaline systems which are often neglected in climate models despite having a potential large influence on carbon flux into the atmosphere.
The GCC postdoctoral network connects our outstanding postdoctoral researchers to our broader GCC community, and provides them with a variety of professional development opportunities such as training in mentorship, grant writing, and science communication.
