I am a planetary geologist specializing in hypervelocity impact processes and dynamic failure of materials. Currently, I am a science team member on the Mini-RF radar and LAMP UV spectrometer onboard the Lunar Reconaissance Orbiter, a member of the Steering Committee and Investigation Team for the AIDA Double Asteroid Redirect Test kinetic impactor mission, and involved in studying phenomenology following hypervelocity impacts into a variety of materials. 

My main research interests include: dynamic properties and failure/fragmentation mechanisms of brittle materials, impact cratering on planetary surfaces (both rocky and icy bodies), planetary surface evolution, lunar lighting analysis for mission planning, modeling impact signature phenomenology, and planetary defense.

My research utilizes experimental facilities such as the NASA Ames Vertical Gun Range, the APL planetary impact lab, and Kolsky bar systems at the Hopkins Extreme Materials Institute, numerical models using the CTH hydrocode, and analysis of planetary spacecraft data.
