Brief Bio


I am a postdoctoral researcher and organic geochemist in the Astrobiology Analytical Laboratory at NASA Goddard Space Flight Center. My research is focused on biomarker preservation and the origins of life. Specifically, I study how molecular fossils form, how they might persist through time, and the transition from natural chemical networks to modern biological systems.

Current Projects


OSIRIS-REx

Astrochemistry

A longstanding question regarding the formation and evolution of the solar system concerns the potential sources and diversity of complex organic compounds which may have contributed to the origins of life on the early Earth. One possibility is that organics synthesized within the early formation of the our solar system may fundamentally represent the most significant source of building blocks (amino acids, sugars, nucleobases). Therefore, organic-rich asteroids and/or meteorites which have persisted with minimal alteration since their formation may serve as time capsules of the primordial solar system, which we can investigate to better understand our planetary and prebiotic origins. As part of the OSIRIS-REx organics analysis team, I am interested in the chemical processes resposible for the formation of prebiotically-relevant compounds and their delivery to planetary surfaces.
