Interests

My research focuses on the problem of planning in large scale, spatial-temporal domains where there is uncertainty and complex dynamics. A good example is forestry planning where many decisions must be made each year about which trees to cut and which parts of the forest to manage in other ways. This problem is complex already due to its scale but it becomes even more difficult when the dynamics of the system lead to high levels of uncertainty and spatial interrelation. This is occurring now in BC with the unprecedented outbreak of Mountain Pine Beetle which are killing most of the pine in BC and are beginning to spread into Alberta. Current methods used in Forestry planning do not deal well with the true uncertainty and spatial interrelation present in the world. I am attempting to apply the strengths of AI techniques in probabilistic modeling, decision theoretic planning and stochastic simulation to develop a general framework that can feasibly perform planning in complex spatial-temporal domains such as these.
