Biography
Dr. Falcy is Assistant Unit Leader and Assistant Professor of Biometrics in the Department of Fish and Wildlife Sciences at the University of Idaho. Matt currently works on fish and wildlife problems that emphasize modeling. Using Bayesian statistics, math, and numerical simulations, Matt’s research seeks to project population dynamics under future conditions. This sometimes includes modeling the interactions between behavior, environment, and other species. Matt is also interested in optimizing human decision-making around management objectives and measures of scientific evidence about the state of nature. Matt teaches graduate courses on Ecological Modeling and Bayesian Analysis in Ecology. Before becoming Assistant Unit Leader in Idaho in 2021, Matt worked for the Oregon Department of Fish and Wildlife for ten years, where he developed salmonid population models and decision support tools. Prior to that, he obtained a PhD in Ecology and Evolutionary Biology with a minor is Statistics from Iowa State University.
