I'm a Ph.D. candidate in the Computer Science department. My advisor is Prof. Vincent Conitzer. I am also sponsored by the J.B. Duke Fellowship.

In the summer of 2012, I was a Summer Associate at Morgan Stanley. I worked in the Systematic Trading group (formerly Equity Trading Lab) in New York.

I help coordinate the Computer Science and Economics (CS-Econ) seminar.

Research

I work in the area of Game Theory. I am currently focusing on security resource allocation games and Bayesian games. My adviser is Vincent Conitzer.

During the summer of 2011, I was a Research Intern at the IBM T.J. Watson Center in the Global Security Analysis Lab led by Reiner Sailer. I designed a game-theoretical model and an algorithm for cyber attack analysis.
