About me

I’m an astrophysicist who uses theory and computational simulations to study space and astrophysical plasmas. Currently, I work as a Postdoctoral Scholar in the Astronomy and Astrophysics Department at the University of Chicago studying collisionless plasma shocks, cosmic ray streaming instabilities and relativistic asymmetric magnetic reconnection.

I received my PhD in Plasma Physics from the University of Delaware in December 2016. My graduate work focused on studying heating in heliospheric magnetic reconnection and kinetic plasma turbulence.
