Born in Chicago, I am currently pursuing a PhD in physics out in California. I did my undergraduate at the University of Illinois, Urbana-Champaign where I worked on black hole accretion. Currently I am a second year graduate student at University of California, Santa Barbara; however, I am currently located at University of California, Santa Cruz. Presently under the advising of Ruth Murray-Clay, I study atmospheric escape on Hot Jupiters. Flip to the next card for my contact information.

Currently I am working in the field of exoplanets theory and simulations—with my work heavily focusing on simulations. My project is performing simulations of planetary atmospheric winds interacting with their host stars. For this work I use the publically available ATHENA to investigate possible underlying physics. Working in 3D, with these simulations I seek to model the non-linear, short timescale behavior of a magnetized atmospheric wind interacting with a time variable stellar environment. Comparing these models to observations will yield the first detailed description of the structure form a quickly escaping atmosphere. In particular, modeling hot Jupiters will allow comparison to the most easily observed class of exoplanet; however, fast thermal escape is thought to be the dominating process shaping the bulk atmosphere of many planets, especially lower mass planets.
