    Dr. Ali Ishaque is a Professor of Environmental Science at University of Maryland Eastern Shore (UMES), Princess Anne, MD. He holds a Ph.D in Ecotoxicology and a M.S. degree in Marine Ecology from the Free University of Brussels, Belgium and a B.S. in Chemistry from the University of Science and Technology, Ghana. He is also the Director of the Graduate Toxicology Program, Coordinator of UMES Salisbury University (SU) Environmental Science Dual Degree Program and Group Leader for Environmental Science at UMES. 

    Dr. Ishaque’s research interest are: identifying molecular biomarkers for contaminant exposure and the effects of mixtures of chemical stressors (non-essential metals and stable xenobiotics) on ecosystems. His focus is in environmental chemical stressors, especially contaminant of emerging concerns and trophic levels relationship. His research focuses on approaches to understand the impact of environmental stressors on environmental quality, develop innovative tools that address biological and molecular mechanisms of environmental stressors, help to assess risk factors and identify health indicators, and develop and support environmental health policy and promote individual and public health. He is also using Fatty acid markers, stomach content analysis and stable isotope ratios to understand trophic relationships and how food web change in relation to environmental factors and climate variability.

    Prior to coming to UMES in August 2001, Dr. Ishaque was a Post-Doctoral Research Associate at Free University of Brussels (VUB), Belgium and at Jackson State University (JSU), Jackson, MS. He is a Board Member of Maryland Coastal Bay Foundation, serves on Advisory Council, Center for the Study of the Health Effects of Fire. Maryland Department of Health and Mental Hygiene. He is also an Editorial Board Member of the Journal of Marine Science: Research & Development- Open Access and Active Member Society of Toxicology. He has published several scientific papers in peer review journals and presented some of his work at national and international scientific meetings.
