Teaching

I've been a teaching assistant for:
11-713 - Advanced NLP Seminar (CMU, Fall 2012)
15-213 - Introduction to Computer Systems (CMU, Spring 2012)
10-701 - Machine Learning (CMU, Fall 2010)
6.857 - Computer and Network Security (MIT, Spring 2009)
6.006 - Introduction to Algorithms (MIT, Fall 2008)

Research

I'm interested in natural language semantics, specifically in producing computer programs that understand natural language. The two questions I'm most interested in are:

I work on the Never-Ending Language Learner (NELL), a system which learns to read using a corpus of webpages. My research includes both work on the underlying knowledge representation and interpreting text given a knowledge representation. I recently gave a talk at the CMU Machine Learning lunch about my recent semantic parsing work.
