I am an Associate Professor in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. My research is focused mainly on impact cratering, which is arguably the most pervasive geologic process in the solar system.

In my group we use numerical models called hydrocodes to study the formation of impact craters and impact processes. Currently we are simulating the formation of large basins throughout the solar system.

I was lucky enough to see the launch of the NASA’s GRAIL mission and have presented at several team meetings. One of my driving goals is to be an investigator on a successful space mission.
