Haider A. Khwaja, PhD is an Associate Professor of Environmental Health Sciences and a Research Scientist at the New York State Department of Health's Wadsworth Center. After getting his PhD from University of New Brunswick, he completed a research associate project on stratospheric ozone layer depletion with Prof. F. Sherwood Rowland (Nobel Laureate, Chemistry, 1995).

Dr. Khwaja believe in French chemist/microbiologist Louis Pasteur’s principle of use-inspired basic research – a goal that is evidenced in the interweaving of research, teaching, and service that make up the fabric of his academic identity. His research and teaching interests lie in the field of Environmental Health. Active research programs include the study of multidisciplinary environmental chemistry related to air and water quality and their impact on human health, sources and fate of chemical contaminants; cloud water chemistry; and acid rain. He has published more than 50 research papers in peer-reviewed international journals including Environmental Pollution, Atmospheric Environment, and Environmental Science and Technology. He is serving as Editorial Member and Editor in refereed journals.
