Research Focus

  • Aquatic toxicological studies in both the laboratory and field involving sediments, single compounds, mixtures, effluents and storm water runoff
  • Ecological risk assessments involving the development of water quality criteria for numerous compounds
  • Continuous versus intermittent toxicity of chemicals
  • Transport/fate/ecological effects of steroids from poultry litter & evaluations of existing/novel management strategies
  • Antibiotics in Land Applied Poultry Litter and Bio solids: Potential for Induction of Microbial Antibiotic Resistance
  • Investigation of Nitrogen, Phosphorus and Sex Steroid Levels in Canada Goose Feces: Water Quality and Endocrine Effects
  • Chronic Toxicity Testing to Determine the Environmental Risks of Proposed Ballast Water Treatment Biocides
  • Development of Acute and Chronic Sediment Quality Thresholds for Lead and Zinc in Baltimore Harbor, MD
  • Laboratory and field aquatic toxicity/bioaccumulation studies involving sediments, single compounds, mixtures, effluents, receiving waters, and storm water runoff

Dr. Fisher is a Senior Research Scientist at the University of Maryland Wye Research and Education Center and the College of Agriculture and Natural Resources Department of Environmental Science and Technology. He earned his Ph.D. in Marine Science/Aquatic Toxicology in 1986 from the College of William and Mary's Virginia Institute of Marine Science. He currently teaches courses at the University of Maryland in College Park concerned with Ecosystem Health and Protection and Environmental Toxicology. He has over thirty years of experience in aquatic toxicology and the study of environmental impacts of contaminants. For 16 years Dr. Fisher directed the Maryland Department of the Environment's Bioassay Laboratory located at the Wye Research and Education Center (WREC) where he conducted acute and chronic whole effluent toxicity testing for NPDES compliance monitoring with freshwater and estuarine fish and invertebrates. In addition, he established freshwater and estuarine sediment toxicity testing capabilities at WREC that allow for sediment quality assessments. He has been the Principal Investigator or Co-PI for research grants and contracts in the following areas: aquatic toxicological studies in both the laboratory and field involving sediments, single compounds, mixtures, effluents and storm water runoff; ecological risk assessments involving the development of water quality criteria for numerous compounds; and continuous versus intermittent toxicity of chemicals. Dr. Fisher’s recent work has been in the assessment of possible endocrine disruptive effects of land applied poultry litter and the development of antibiotic resistance in Eastern Shore streams from poultry litter and biosolids application. He has written more than 100 refereed journal and technical publications on a wide variety of environmental issues.
