I am a Ph.D. candidate in the Department of Computer Sciences at
the University of Texas at Austin. My
advisor is Professor Vladimir
Lifschitz. I am part of Texas Action Group at
Austin, a group of researchers working on logic-based artificial
intelligence.
My Dissertation is A Modular Language for Describing Actions.
