Planetary impacts, asteroid dynamics
My research interests at this time fall primarily into the following areas:
1) atmospheric impacts (i.e. impacts of asteroids and comets into planetary atmospheres),
2) crater formation by impacts, especially of multiple or disrupted bodies,
3) impact-generated tsunami on the Earth, and
4) asteroid dynamics (including internal structure, spin-states, surface processes, and origin of binaries).
In addition, I am working on extending the asteroid-dynamics computations to granular-flow and landslide modeling.
I am also part of the NASA-Ames Lunar CRater Observation and Sensing Satellite (LCROSS) mission science team.
My work consists mostly of numerical modeling: I use codes developed by others (ZEUS-MP, COULWAVE) for impact and hydrodynamical modeling, and ones developed by myself (for rigid-body dynamics).
