About Me

I am a fourth year PhD Student at Brown. I work on developing statistical models for explaining images and text. My advisor is Erik Sudderth. Before Brown, I spent a few years in beautiful Boulder getting my master's degree from the University of Colorado. At Colorado, I was advised by Jane Mulligan. Going further back, I went to the University of Mumbai (Bombay) (KJSCE, for those who know/care) as an undergrad.
