My current research orientation is the application of dynamic optimization methods to natural resource management problems. I am active both in developing plans for managing wildlife, endangered and invasive species as well as in the development of methodological approaches for solving dynamic optimization problems and for addressing structural and observational uncertainty. My published work also includes studies of commodity price behavior, commodity derivatives (futures and options) markets and computational economics. I co-authored (with Mario Miranda) a widely used textbook on computational economics; we also co-developed the associated computer package (CompEcon). I am currently working on two new textbooks on natural resource management and I’ve been developing an associated computer package (MDPSolve).
