I model the atmospheres of sub-Neptunes — aerosols, photochemistry, and climate — and work on planetary and galactic dynamics besides.

About

About

I'm a PhD student and NSF Graduate Research Fellow in the Department of Astronomy & Astrophysics at the University of Chicago.

I work with Diana Powell and Peter Gao on modeling sub-Neptune atmospheres, focusing on aerosols, photochemistry, and climate. My interests are fairly broad, though — I also work on problems at the intersection of planetary and galactic dynamics.
