Tutorial

Here is a tutorial on first-order probabilistic languages that I presented with Lise Getoor at IJCAI 2005.

Research

My research focuses on the design of intelligent systems that perform well in the real world. The world is a challenging place - it is large and complex, and it keeps on changing, often in unpredictable ways. I am particularly interested in systems that can deal effectively with uncertainty. Some current projects:

IBAL: A general representation language for probabilistic reasoning and decision-theoretic agents

Modeling agents' beliefs and decision making processes in games

Probabilistic models of music

Efficient hierarchical probabilistic inference in dynamic systems

Older projects:

Probabilistic Reasoning for Complex Systems

Learning Rich Probabilistic Models

Effective Algorithms for Game-Theoretic Problems
