Research interests include conditions of early Earth during the initiation of life; constraining the amount of continental lithosphere through time; understanding the flux and timing of asteroids impacting the Earth-Moon system and the association with major extinction events; and the evolution of the Himalaya and the Tibetan Plateau.
Current Research Projects
- Impact flux to Earth-Moon system through time
- Early Earth research
- Global effects due to impact including mass extinction events
