I am a fourth year grad student advised by Professor Andrew McCallum. Before that, I was an Associate Scientist in the Speech, Language, and Multimedia Department at Raytheon BBN Technologies, where I worked on multilingual optical handwriting recognition. I received a B.A. in mathematics from Harvard University, where I worked with Eric Dunham and Jim Rice. We developed methods for numerically simulating earthquake ruptures along rough fault surfaces. Currently, my research focus is on machine learning and natural language processing. In 2014, I interned with Sham Kakade at Microsoft Research New England. I co-organize the weekly UMass Machine Learning and Friends Lunch.
