I am an Associate Professor in the Department of Information System Engineering, at Ben-Gurion University. My main research area is Heuristic Search. I am also interested in agents operating in unknown environments. In the area of heuristic search my main focus is to find and study new algorithms as well as new heuristic functions for single agent search problems. Recently, together with some of my students and colaborators I have started to work on the in the multi-agent path finding problem which can be expressed as a single-agent search problem.
