Dr. Debashish Sengupta is a Professor, Higher Administrative Grade and Head of the Department of Geology and Geophysics in Indian Institute of Technology Kharagpur, West Bengal, India. Dr. Sengupta has more than 25 years of teaching and research experience. He has completed his PhD in 1987 in Applied Geophysics. His areas of interests are nuclear geophysics including petroleum logging using subsurface nuclear data, radioactive methods and geochronology, radon emanometry and its applications, applications of isotopes and radionuclides in earth and environmental geosciences, heat flow and geothermics. Dr. Sengupta has 73 research publications in international journals and more than 50 papers in Conference Proceedings apart from a large number of Invited Talks delivered both in India and abroad. The research work has been seminal and resulted in the formulation of Environmental Regulation policies in various countries both in India and countries like USA, South America and the European Union. Dr. Sengupta had also been a Visiting Professor at the University of Sao Paulo, Brazil and as Senior Visiting Professor at the University of Salamanca, Spain, earlier, while on a sabbatical leave from the institute. He has received Society of Geoscientists and Allied Technologists (SGAT’s) Award of Excellence in Earth Sciences for the year 2003. Till date, 9 students have been awarded PhD degrees under his supervision.
