I graduated cum laude in physics and mathematics from Cornell University in 2015 and received my Ph.D. in Astrophysical and Planetary Sciences in 2022 from the University of Colorado Boulder, advised by Prof. Juri Toomre. Since Fall 2022, I have been studying Astronomy and Astrophysics in Applied Mathematics with Prof. Nicholas Brummell, as an NSF Postdoctoral Fellow. I am studying the behavior of stellar dynamos (partially convective G-type solar-like stars and fully convective M dwarfs) as they spin down.


Stellar dynamo theory, astrophysical fluid dynamics, magnetohydrodynamics (MHD), MHD simulations. 

stellar magnetic fields; stellar convection; stellar differential rotation; instabilities, waves, and turbulence

I was a teaching assistant for Accelerated Intro to Astronomy II at the University of Colorado for two semesters and hope to continue teaching udnergraduate astrophysics at some point in the future. Under the NSF, I am funded to establish a multi-disciplinary peer mentoring program among grad students and postdocs, joint between Applied Mathematics and Astrophysics.
