Dr. Amitava Bandyopadhyay received his BTech in 1988 from the University of Calcutta, and his MTech in chemical technology and PhD in chemical engineering in 1990 and 1996 respectively from the Indian Institute of Technology, Kharagpur. Before joining as a faculty member in the Department of Chemical Engineering at the University of Calcutta, he served for more than ten years in a senior position in the State Regulatory Agency, dealing with the implementation of various environmental rules and regulations. One of his technical reports submitted to the State Environmental Regulatory Agency has changed the National Effluent Discharge Standards of Indian Petroleum Oil Refinery Industry Sector. He was a faculty member of the World Bank concerning the development of emission standards for Indian petrochemical industries. He has worked in several organizations before joining in the State Environmental Regulatory Agency. Besides his active background in teaching, his major research areas include waste minimization, advanced separation processes, CO2 capture, and emission control. He has published more than 60 articles in peer-reviewed journals and authored two books. He is one of the topical editors of water and environmental engineering in CLEAN – Soil, Air, Water, is the editor-in-chief of the Open Journal of Air Pollution, has acted as a guest editor for Separation and Purification Technology, and is a member of the editorial board of Journal of Water Resource & Protection. He has reviewed projects funded at both international and national levels and is a member of various institutions and governmental departments in India. Dr. Bandyopadhyay has received several laurels for his excellent research works. He has organized several seminars, conferences, and workshops and chaired a number of technical events on chemical environmental engineering. Dr. Bandyopadhyay is a life member of several professional bodies and is a fellow of the Indian Water Works Association.
