I am a sixth-year Ph.D. student in mathematics and ACO at Georgia Tech. I received my
B.S. in math from Caltech in 2011.

My research interests include discrete math and theoretical computer
science, including graph theory, algorithms, complexity, and
computability. I am currently working with Prasad Tetali on various extremal problems in enumerative graph theory and on Markov chain mixing. I am also interested in combinatorial aspects of machine learning theory.

## Academics

This is my CV as of August 2016.

From Spring 2014 through Spring 2015 I was a co-organizer of the ACO Student Seminar, which aims to give students and postdocs a forum to share their research results or present on a topic of general interest.

## Hobbies

I like to sing and play the cello, but I'm not very good at the
viola or violin. I am particularly fond of Renaissance madrigals and Romantic era chamber music.
