David is currently a Research Space Scientist at the NASA Goddard Space Flight Center. In 2013, he received his PhD in geological sciences from Brown University, studying the formation of large impact craters on Mercury and the Moon and glacial processes on Mars.
David's research seeks to integrate a range of remote sensing datasets from multiple planetary bodies in order to understand how geological processes have operated on these bodies through space and time. His current research interests focus on interplanetary comparisons of impact cratering on Mercury, the Moon, and Mars and cryospheric processes on Mars and Earth. His research techniques and methods include geomorphic mapping, quantitative morphometric measurements, visible/near-infrared spectral analysis, radar interpretation, and gravity analysis.
David is also a member of the Planetary Data System (PDS) management team in the PDS Project Office at Goddard Space Flight Center. The PDS Project Office provides operational oversight for all of the PDS nodes and is involved in a variety of interactions with NASA's Planetary Science Division management.
