About

I am a CLE Moore Instructor and an NSF Postdoc at MIT broadly interested in the interplay between harmonic analysis, geometric measure theory, the calculus of variations and PDE. At MIT my sponsoring scientist is Professor David Jerison and most of my research here has been on problems related to free boundary regularity.

I will be starting as an Assistant Professor (Tenure Track), at the University of Minnesota, Twin-Cities in the summer of 2019.

**Past Positions:** Up until June of 2016, I was a graduate student at the University of Chicago and my advisor was Professor Carlos Kenig. You can find my thesis, on free boundary problems for harmonic
and caloric measure, here (and you can see a picture of me defending said thesis to the right). While in graduate school I spent several months at the University of Washington, working with Professor Tatiana Toro I spent the Spring of 2017 at MSRI as a postdoc in the Harmonic Analysis program, where my mentor was Professor Svitlana Mayboroda.

While applying to the NSF Postdoc, I found it very helpful to read several previous proposals which other mathematicians made available on their websites. In that spirit, here is my NSF Summary and NSF Description from my sucessful NSF Postdoc Application in the Fall of 2016. I also applied unsucessfully for the NSF postdoc in the fall of 2015, but seem to have lost those materials.
