Brief Bio


I am a Research Space Scientist in the Planetary Systems Lab at the NASA Goddard Space Flight Center. I received my PhD in Earth, Environmental and Planetary Sciences from Brown University in 2018. Prior to coming to NASA, I was a postdoc on the OSIRIS-REx mission.

My scientific research involves remotely characterizing the chemistry and mineralogy of planetary surfaces. I have worked with visible – near-infrared spectral data from multiple spacecraft and am particularly interested in infrared spectroscopy of organics, connecting laboratory and spacecraft spectral data, and spectroscopy of carbonaceous asteroids and meteorites.
