About Me
About Me
I'm a sixth year PhD student in Applied Mathematics at University of Arizona, working on astrophysical fluid dynamics. Using both analytic and numerical approaches, I study hydrodynamic instabilities in planet-forming disks.
I also became interested in cloud formation in exoplanet atmospheres during the lovely Kavli Summer Program in Astrophysics, and I've been working with my mentors since.
Outside of research, you'll probably find me somewhere in the Sonoran Desert, drenched in sweat and wondering why I do this to myself.

I'm working with Prof. Andrew Youdin on theoretical aspects of the Rossby Wave Instability (RWI). Recently I've been taking a look at the RWI through analyzing FARGO3D simulations of planet-disk interactions.
I'm also investigating how external dust infall influences changing cloud properties of giant exoplanets from Hot Jupiters to young, directly imaged planets. I use PICASO climate models and CARMA microphysics.
