I am a PhD candidate in the Computer Science department at UT Austin. My research interests include distributional semantics, deep learning, textual inference and general natural language processing. I am supervised by Katrin Erk, and affiliated with the UTCS Machine Learning lab. I expect to graduate in mid 2017.
I'm most easily reached via my email, firstname.lastname@example.org.
