John Farrell

Dr. John Farrell is Professor and Director of the Thousand Island Biological Station in the Department of Environmental Biology at SUNY College of Environmental Science and Forestry. He teaches Ichthyology, Aquatic Ecosystem Restoration, and Senior Synthesis courses. His research program focuses on aquatic ecology, fisheries management, and ecosystem restoration in Great Lakes ecosystems.

Research investigates fish ecology (particularly northern pike and muskellunge), coastal wetland dynamics, invasive species impacts (round goby, rudd), and habitat restoration techniques. Recent publications (2019-2025) emphasize: 1) Habitat connectivity restoration (40% of articles), 2) Invasive species ecology (25%), 3) Microbial ecology of fish (20%), and 4) Genomic approaches to conservation (15%).

He mentors graduate students in fisheries ecology and leads field research in the St. Lawrence River ecosystem. As station director, he oversees long-term monitoring of fish populations and wetland habitats.
