I am a planetary geologist specializing in hypervelocity impact processes and dynamic failure of materials. Currently, I am a Co-I on the Mini-RF radar and LAMP UV spectrometer onboard the Lunar Reconaissance Orbiter, a Co-I on the Dragonfly mission, a team member on the Europa Imaging System (EIS) on Europa Clipper, the lead for the Impact Modeling Working Group on the Double Asteroid Redirection Test (DART) mission, and a member of the Steering Committee and Investigation Team for the AIDA international collaboration. I am also involved in studying phenomenology following hypervelocity impacts into a variety of materials, and am a member of the NASA NEO Action Plan Modeling Working Group. My main research interests include dynamic properties and failure/fragmentation mechanisms of brittle materials, impact cratering on planetary surfaces, 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.
