## About

I am a PhD student in Computational Math at Stanford University advised by Jure Leskovec. My research focuses on network science, matrix computations, and data mining. I have interned with Google (2015, 2012, 2011), Sandia National Labs (2014), and HP Labs (2013). Before coming to Stanford, I studied EE/CS and Applied Math across the bay at Berkeley.

My research is currently supported by a Stanford Graduate Fellowship.
