My research investigates abiotic chemical processes that may have played a role in origins of life on Earth. Specifically, I am currently working to understand abiotic formation of amphiphilic compounds, which are lipids that possess both hydrophobic and lipophilic properties, and are important components of contemporary cell membranes. In collaboration with researchers from NASA Ames and NASA Goddard Space Flight Center, I am investigating the potential for amphiphilic compounds to form in interstellar molecular cloud environments characterized by low temperatures, low pressures, and impacted with irradiation. I am also considering the potential for abiotic formation of lipids in hydrothermal environments, and the effects of clays and other minerals to catalyze aqueous Fischer Tropsch Type reactions.
