Research Interests

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 which includes three main themes:

  1. Connectivity and River Restoration
  2. Physiology and Behavior of Migration
  3. 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).

Teaching Interests

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" and "Quantitative Freshwater Fisheries Ecology"), 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.
