My research interests include topics in machine learning, algorithmic game theory, social networks, computational finance, and artificial intelligence. I often examine problems in these areas using methods and models from theoretical computer science and related disciplines. While the majority of my work is mathematical in nature, I have also participated in a variety of empirical and experimental work, including applications of machine learning in finance, spoken dialogue systems, and other areas. Most recently, I have been conducting human-subject experiments on strategic and economic interaction in social networks.
