I am working in Rina Dechter's group, I started my studies towards a Ph.D. in the School of Information and Computer Science at UC Irvine in the fall of 2006.

 


Research

My area of concentration is artificial intelligence, where I am trying to exploit structure in problem solving. The reasoning tasks I deal with can typically be expressed as graphical models and comprise constraint satisfaction and optimization problems as well as queries over Bayesian belief networks (e.g., P(e), MPE, belief updating).

My research circles around the two central approaches of inference (variable elimination) vs. conditioning (search). Currently I am investigating automatically generated heuristics for search. I have also been looking at different complexity measures for reasoning problems represented as graphical models and how to bound instance-based complexity in the presence of determinism. More recently our group has started applying our techniques to problems originating in human genetics.

Our research group recently launched a website where we make available implementations of the algorithms we develop: http://graphmod.ics.uci.edu/.

 


Personal

Before coming to UCI I was a student at RWTH Aachen University in Aachen, Germany and Chalmers University of Technology in Gothenburg, Sweden.
