Dr. Feldman’s research training is in theoretical physics and mathematics, and his research interests lie in the fields of statistical mechanics and nonlinear dynamics. In particular, his research has examined how one might measure "complexity" or pattern in a mathematical system, and how such complexity is related to disorder. This work can be loosely categorized as belonging to the constellation of research topics often referred to as "chaos and complex systems." In his research, he uses both analytic and computational techniques. Professor Feldman is a frequent visiting researcher at The Santa Fe Institute and is an Associate Graduate Faculty member in the Department of Physics and Astronomy, University of Maine.

BA, University of California at Santa Barbara, Aquatic Biology
PhD, University of Arizona, Tucson, 1985, Ecology and Evolutionary Biology

Dr. Peterson’s work involves a variety of questions concerning the evolution and ecology of marine organisms, emphasizing tropical reef fishes. Most of his work has focused on the reproductive biology of tropical and temperate marine fishes. Undergraduates are involved  in several research projects, and some have co-authored papers.
