Graham Sherwood


Graham's research focuses on the intersections between food web ecology, fish bioenergetics and fisheries ecology. He is particularly interested in how variations in prey availability and prey type/size can lead to variations in fish energetics, production and/or recovery capacity (e.g., growth, condition and fecundity) in a wide range of commercially exploited fishes (e.g., Atlantic cod, haddock, monkfish and Atlantic herring).

Eric Bridger


Eric has been a Senior Software Engineer at the Gulf of Maine Research Institute since November 2009. Prior to joining GMRI, Eric worked for 7 years for the Gulf of Maine Ocean Observing System (GoMOOS) which merged with GMRI in 2009. He has worked for years promoting and implementing Open Geospatial Consortium (OGC) standards for sharing of ocean observations and model data in an interoperable and open way leading to the development of an integrated ocean observing system in the United States and the world (IOOS, GEOSS).

Lisa Kerr


Lisa is a fisheries ecologist broadly interested in understanding the structure and dynamics of fish populations, with the goal of enhancing our ability to sustainably manage fisheries and ecosystems as a whole. She is particularly motivated to understand the role complex population structure and connectivity play in the productivity and stability of local and regional populations.

Andrew Pershing

Andy took over as GMRI's Chief Scientific Officer in 2014 and continues to run the Ecosystem Modeling Lab. Prior to becoming CSO, Andy had a joint appointment as a faculty member in the University of Maine School of Marine Sciences and as a research scientist at GMRI. His research focuses on the causes and consequences of changing conditions in the Gulf of Maine, and he is an expert on how climate variability and climate change impact the ecosystems in the northwest Atlantic.

Walt Golet

Walt is an Assistant Professor at the University of Maine's School of Marine Sciences and serves as a Research Scientist at the Gulf of Maine Research Institute. Walt came to UMaine and GMRI after completing his Ph.D. at the University of New Hampshire in May 2010. Since then, Walt has been studying the energetic condition, spatial distribution, foraging ecology, age and growth of bluefin tuna and broadbill swordfish in the Atlantic. A key finding from Walt's dissertation was that tuna in the Gulf of Maine were skinnier during the 1990's.
