My research interests are in the area of artificial intelligence, with an emphasis on scheduling and heuristic search. Recently I have focused on distributed scheduling for a team of collaborative agents in a dynamic environment, where the goal is to maximize the quality of the actions executed by all the agents. I have also performed research and published papers in combinatorial optimization, genetic algorithms and the empirical evaluation and analysis of algorithms.
