Barry P Baldigo
Barry Baldigo has been a Research Biologist with the U.S. Geological Survey since 1990. He leads numerous collaborative studies that aim to improve our understanding of the health of aquatic ecosystems, impacts of environmental contaminants and hydrologic modification, important interrelations, and management options that help mitigate ecological disturbance and sustain valuable natural resources.

Professional Experience
Research Biologist (RGE); U.S. Geological Survey, Troy, NY; 1990-present: Principal investigator for cooperative water programs (with NGOs, and county, regional, and state agencies) evaluating interrelations among restoration, channel stability, habitat, and fish communities; tissue contaminants and toxicity of water and sediments in Areas of Concern across the Great Lakes; basin features, impound
Senior Biologist; Adirondack Lakes Survey Corp, Raybrook, NY; 1988-1990: Field coordinator for the EPA’s Episodic Response Project assessing effects of episodic acidification on water quality, fish survival, and biologic communities in streams of the southwestern Adirondack Mountains, New York.
Senior Scientist; Lockheed Engineering and Sciences Co., Las Vegas, NV; 1984-1988: Lead investigator for several EPA technical-support projects in the Northwest and regional coordinator and instructor for EPA’s NSWS Eastern and Western Lakes-, Eastern Stream-, and Michigan Lakes Biology and Acidification Surveys.
Research Biologist; University of Nevada, Dept. of Biological Sciences, Las Vegas, NV; 1980-1984: Invertebrate taxonomist and technician; helped develop and assess new field guidelines for modifying EPA’s national site-specific water quality criteria (NPDES permitting program) and stream biological assessments.
