I am a postdoctoral research fellow at University of Oxford and a member of Magdalen College. My research is supported by a Glasstone Research Fellowship. My CV is available.

I am interested in analytic number theory and arithmetic combinatorics in general, and more specifically I like topics regarding character and exponential sums, sieve theory, Szemeredi's theorem in the integers and in the primes, structures in sumsets, etc.

Previously I was a PhD student at Stanford University under the supervision of Prof. K. Soundararajan.
