I am an Instructor at the University of Pennsylvania. I was also a Vice Provost Postdoctoral Fellow at the University of Pennsylvania from 2017 to 2020, my mentor was Ryan Hynd. I completed my Ph.D. at Rutgers University in May of 2016 under the supervision of Eric Carlen. My research is in functional inequalities and elliptic PDEs.

My CV is at the bottom of this page.
