Biography

Joshua Lipton, Ph.D. Joshua Lipton, Ph.D.
Joshua Lipton is an environmental toxicologist with expertise in aquatic and terrestrial toxicology, applied ecology and fisheries biology, natural resource damage assessment, and the evaluation of environmental impacts and risk.

Prior to joining Abt Associates, Lipton was President, CEO, and Chairman of the Board of Stratus Consulting, an environmental research and consulting firm that was well known for high-level technical excellence and innovation in environmental sciences and natural resources, environmental economics, environmental information management, litigation support, and policy analysis. Stratus Consulting merged with Abt Associates in February 2015.

Lipton’s toxicological research activities have included investigations into the bioavailability of metals to fish and plants, sub-lethal and behavioral responses of organisms to hazardous substances, effects of acclimation and adaptation on sensitivity to metals, community/ecological responses to chronic contamination, lethal and sub-lethal effects of petroleum hydrocarbons on marine organisms and communities, and reproductive, sub-lethal, and behavioral effects of chlorinated organics.

Lipton has directed field studies on fish and wildlife populations, field studies on aquatic and terrestrial habitat and community composition, and extensive environmental sampling and monitoring programs. Lipton – an internationally known expert and leader in the field of natural resource damage assessment (NRDA) – has served as lead scientist on many of the prominent natural resource injury and damage investigations performed in the U.S., and has been involved in guidance level and has lectured widely on NRDA and environmental effects evaluation in North America, Europe, and Asia.

Lipton has published peer-reviewed articles in scientific journals such as the Canadian Journal of Fisheries and Aquatic Sciences, Environmental Toxicology and Chemistry, Ecotoxicology, Transactions of the American Fisheries Society, Environmental Management, and Aquatic Toxicology. He has been an invited speaker and lecturer at conferences and universities and for government agencies, has served on the editorial boards of Environmental Toxicology and Chemistry and Science of the Total Environment, and has served as a peer reviewer for other scientific journals. He also served as a Research (Full) Professor at the Colorado School of Mines.

He holds a B.A. in ecology from Middlebury College and a Ph.D. in natural resources/environmental toxicology and an MS in natural resources from Cornell University.

Middlebury College is a private liberal arts college located in Middlebury, Vermont, in the United States. Founded in 1800, it is one of the oldest liberal arts colleges in the United States. Drawing 2,500 undergraduates from all 50 states and over 70 countries, Middlebury offers 44 majors in the arts, humanities, literature, foreign languages, social sciences, and natural sciences. Middlebury follows a 4–1–4 academic calendar, with two four-course semesters and a one-course January term. Middlebury is the first American institution of higher education to have granted a bachelor's degree to an African-American, graduating Alexander Twilight in the class of 1823. Middlebury was also one of the first formerly all-male liberal arts colleges in New England to become a coeducational institution, following the trustees' decision in 1883 to accept women.
