Years with LPL: 2017

I specialize in planet formation resulting from pairwise collisions ('giant impacts') and the physics of low-gravity bodies such as comets, small satellites and asteroids. I also dabble in the evolution of the martian and lunar surface, and the origin of chondrules. I am pursuing the development of laboratories in near-Earth space relevant to accessing and processing in situ resources, and missions to asteroids and comets.
