About
I am currently a postdoc at the Harvard Center of Mathematical Sciences and Applications, where I have been working with David Nelson and L. Mahadevan. As a theoretical physicist, I am interested in soft matter and biophysics, particularly active matter, liquid crystals on curved surfaces, topological defects, morphogenesis, and the interplay between geometry and topology.
I received my PhD in physics from the University of California, Santa Barbara, where I was advised by Boris Shraiman. As a graduate student, I also worked with Cenke Xu on topological aspects of hard condensed matter physics as well as Cristina Marchetti and Mark Bowick in soft matter.
Prior to that, I received an AB in physics and mathematics from Harvard College. As an undergraduate, I attended the Caltech LIGO SURF REU under Yanbei Chen.
I also co-organize with David Nelson the Harvard CMSA Active Matter Seminar. We encourage anyone interested broadly in active matter research to attend.
Here is my CV.
