I'm a graduate student at the Harvard department of Physics, where I am fortunate to work with David Nelson under the support of NSF GRFP and the Paul and Daisy Soros Fellowship. I am broadly interested in the statistical physics of condensed matter and biological systems. Before coming to Harvard, I completed my undergraduate degree in physics at Massachusetts Institute of Technology. I also enjoyed a research internship on Google's applied science team.
