About me

I’m an astrophysicist who uses theory and computational simulations to study space and astrophysical plasmas. I have recently started as an Assistant Professor at the Institute for Astronomy at the University of Hawaiʻi, Mānoa working on understanding shocks, cosmic rays, magnetic reconnection and turbulence.

I received my PhD in Plasma Physics from the University of Delaware in 2017 which focused on heliospheric magnetic reconnection and kinetic plasma turbulence. I worked as a postdoc in the Department of Astronomy and Astrophysics at the University of Chicago until 2021 studying collisionless plasma shocks.
