Dr. Valtorta's research interests are in the areas of normative reasoning under uncertainty (especially Bayesian networks, influence diagrams, causal models, identifiability issues, and applications in multiagent systems), heuristics for problem solving, and computational complexity in artificial intelligence. As a faculty member, he has conducted research funded by ARDA, SPAWAR, DARPA, the Office of Naval Research (ONR), the U.S. Department of Agriculture (DOA), CISE (an Italian laboratory controlled by ENEL, the state electricity company), and the South Carolina Law Enforcement Division. He currently leads the USC part of a multi-institution IARPA-funded project on the synergistic use of Wigmorean inference networks and Bayesian networks to support argumentation and collaborates with Dr. Linyuan Lu of the USC mathematics department in an ONR-funded project on the Markov properties of directed hypergraphs.
