Biography
Joe joined the Maine Cooperative Fish and Wildlife Research Unit in 2004 as Assistant Unit Leader, coming from the USFWS Columbia River Fisheries Program Office. He is a Professor of Fisheries Science in the Department of Wildlife, Fisheries at the University of Maine, Orono. Joe's work centers on the study of fish movements and migrations. Many vital fisheries issues in the northeast United States are dependent upon a rigorous understanding of life history expression. He has effectively addressed both basic and complex management questions in innovative ways, developing a program that includes three main themes: i) Connectivity and River Restoration ii) Physiology and Behavior of Migration, and iii) Species Interactions. As a critical part of his position, Joe's work is responsive to the requests of MCFWRU cooperators (e.g., Maine Department of Inland Fisheries and Wildlife, the University of Maine's Department of Wildlife, Fisheries, and Conservation Biology and US Fish and Wildlife Service). As part of his appointment to the graduate faculty at the University of Maine through the MCFWRU, Joe provides graduate instruction in the form of formal courses (e.g. "Movements and Migration", directing independent studies of selected topics (fisheries science, migration biology), and interacting with graduate students. Joe serves on numerous committees as degree program advisor, co-advisor, or committee member.
