I received my Ph.D. from MIT in 2018. I am now a Hans Rademacher Instructor at the University of Pennsylvania. I'm interested in algebraic geometry and number theory. My advisor is Bjorn Poonen. I received my B.A. from UC Berkeley in 2013. Here is my CV.

- Galois covers of curves in characteristic p
- Fundamental groups of curves
- Ramification theory
- Abhyankar's conjectures

- Local-to-Global Extensions to Wildly Ramified Covers of Curves
- Constants in Titchmarsh divisor problems for elliptic curves
- Energy Measures of Harmonic Functions on the Sierpinski Gasket, with Ching-Wei Ho and Robert Strichartz, Indiana Univ. Math. J. 63 (2014), 831-868.

- I was an organizer for the STAGE seminar at MIT.
- I'm very invested in improving mental health and strengthening the community at MIT. To this end, I run the projects Free Gifts and moderate on MIT|Discussion.
