to the web site of Phil Armitage at JILA, where I am an Adjoint Fellow with interests in theoretical and computational astrophysics. Current
areas of interest include the dynamics of strongly magnetized disks around black holes, the formation of planetesimals, the accretion of
planetary envelopes, and the use of machine learning to study planetary system evolution. I am based jointly at Stony Brook University
, and at the
Flatiron Institute's Center for Computational Astrophysics
, where I currently lead the Planet Formation group. At JILA I collaborate closely with Mitch Begelman and his group.
I maintain separate websites for my current research, and for landscape and wildlife photography. Occasional short videos go to a YouTube hiking channel.
