Bio Sketch

Throughout his life, Andy has been on a personal crusade to ensure that fish are around for future generations to enjoy, whether on the end of a fishing line, on a dinner plate, or simply to watch in wonder. His work spans both marine and freshwater systems. Broadly, Andy is a spokesperson for fish conservation, advocating for positively affecting change when it comes to fish and the complex social-ecological systems they are nested in. Much of Andy’s current research focuses on movement ecology, recreational fisheries, and understanding the impacts of natural and anthropogenic disturbances on teleosts and elasmobranchs. Andy is an award-winning educator, receiving a Distinguished Teaching Award at UMass Amherst (2014), and an Award of Excellence in Fisheries Education from the American Fisheries Society (2021). Andy also puts a great deal of energy towards stakeholder engagement and knowledge co-production in which has been acknowledge by receiving an award for Excellence in Public Outreach from the American Fisheries Society (2017) and the Flats Stewardship Award from Bonefish & Tarpon Trust (2020). Most recently, Andy was inducted as a Fellow of the American Fisheries Society (2024). To help broader efforts related to fish conservation, Andy is a fly fishing ambassador for Patagonia, the Science Advisor for Keep Fish Wet, a Scientific Affiliate for International Game Fish Association, Bonefish & Tarpon Trust Research Fellow, Board Member for Indifly (Foundation), and Fellow for The Explorers Club.
