Dr. SenGupta’s research interests include preparation, characterization and innovative use of novel adsorbents; ion exchangers; reactive polymers; specialty membranes in environmental separation and development of sustainable environmental processes. He is a leader in environmental technology research and education, and has guided dozens of graduate students to successful careers in engineering practice and research.
Dr. SenGupta’s award-winning research has expanded the field of ion exchange science and technology in solving critical environmental problems, and has led to the development of new classes of hybrid ion exchangers that have been incorporated into water and wastewater treatment processes globally. He heads an international, interdisciplinary effort to develop and promote a sustainable treatment system that provides drinking water free of arsenic to thousands of people all over the world. He developed and helped to commercialize the first polymer-based absorbent for arsenic in the U.S., a product that provides arsenic-safe water to well over one million people in both the developing and the developed waorld. SenGupta currently has seven US patents.
Dr. SenGupta’s innovations in environmental engineering and his collaborative work with university researchers and local engineers in developing nations have been recognized with a multiplicity of awards, including the 2001 Frontier Research Award from the Association of Environmental Engineering and Science Professors (AEESP); the International Ion Exchange Award from Cambridge University; the Grainger Silver Award from the National Academy of Engineering (NAE); the National Collegiate Inventors and Innovators Alliance (NCIIA) Sustainability Award; the Dhirubhai Ambani Award from the Institution of Chemical Engineers (UK); the Astellas USA Foundation Award from the American Chemical Society (ACS); and the Lawrence K. Cecil Award from the American Institute of Chemical Engineers (AIChE).
Dr. SenGupta teaches courses in environmental chemistry, reaction kinetics in environmental engineering, and environmental separation and control. He also teaches a hands-on engineering course for first-year students as well as an introductory environmental engineering course. In addition, he holds a joint faculty appointment in Lehigh’s department of chemical engineering and served as the department chair in civil and environmental engineering from 1998–2005. SenGupta was the lead faculty to introduce all three degree programs (BS, MS and PhD) in environmental engineering at Lehigh University.
SenGupta is a member of the American Chemical Society, the American Institute of Chemical Engineers, the American Society of Civil Engineers, the American Water Works Association, the Association of Environmental Engineering and Science Professors, and the Water Environment Federation.
