Welcome! I am a PhD student at UC San Diego, working in machine learning. I am advised by Yoav Freund, and received my M.S. in Computer Science from UCSD in spring 2013. My current research interests include developing semi-supervised algorithms to combine ensembles of predictors, and studying sequential processes and learning.

Before the PhD, I was an Associate at Strand Life Sciences, where I did statistical genomics, developing tools for genomics researchers. Previously, I received a B.S. (High Honors) in Electrical Engineering and Computer Science at UC Berkeley in December 2008. On the way to that degree, I minored in (quantum) physics at Berkeley as well. Before that, I lived in various parts of India, the US, and Singapore.
I used to play the violin (and occasionally still do); before college, I happened to do a certification in it (unfortunately recordings are lost!). I also played the Carnatic classical style, which is less polyphonic but melodically far richer.
I have always enjoyed traveling and do so whenever the opportunity arises. In my free time, I sometimes write on history and philosophy tidbits I find interesting (links to come).
