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.
