About Me
About Me
I'm a fifth year graduate student in Applied Mathematics at University of Arizona, where I research fluid dynamics in astrophysical settings, particularly planet-forming disks. My work combines theoretical modeling and numerical simulations (with a bit of machine learning) to study fluid instabilities in these environments.
Outside of research, you'll find me in the kitchen honing my culinary skills, or making very slow progress on beginner-level guitar.
Or out in the Sonoran Desert. Drenched in sweat. Questioning life choices. But somehow moving forward. (Some call it hiking)

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.
