Andy is a planetary astronomer at the Johns Hopkins University Applied Physics Laboratory in Laurel, MD, with his research focusing on the composition of asteroids. In particular, he is interested in those asteroids that have evidence of water or organic materials in them, detectable in their infrared reflectance spectrum. This pursuit has led to studies of asteroids all over the inner solar system, from dwarf planets to objects that can fit inside a sports stadium.
In addition to observational work, Andy has been active in the broader near-Earth object community, serving as a team member in several efforts to understand and report the impact hazard we face and how to lessen it, including serving as Investigation Lead for the DART mission scheduled to conduct a planetary defense demonstration in 2022. Finally, Andy is the Principal Investigator of the MANTIS mission concept, which if selected by NASA will conduct an asteroid tour in the 2020s.
