Dr. Chandrashekhar Bhuiyan is a researcher in the field of Applied Geoscience. He obtained his Bachelor's in Geology from the University of Burdwan followed by his M.Tech. in Applied Geology from the University of Roorkee (presently, Indian Institute of Technology Roorkee), and his Ph.D from Indian Institute of Technology Kanpur. He is a DAAD Fellow, and carried out a part of his doctoral research at the Friedrich Schiller University, Jena, Germany through DAAD "Sandwich-model PhD" programme. He has post-PhD research experience at several national and international institutes including School of Environmental Sciences, Jawaharlal Nehru University and School of Environmental Studies, University of Delhi. Dr. Bhuiyan was a recipient of DAAD 'Reinvitation Fellowship' to visit the University of Cologne, Germany in 2009 as a Visiting Scientist. He has authored more than 25 research articles in reputed international journals and conferences, and also published several book chapters. His research interests include hydrogeology, extreme hydrology, water resources, aquifer vulnerability modelling, artificial groundwater recharge, and natural hazards. He has carried out extensive research on hydrogeological modelling, drought dynamics, water resources assessment, and water scarcity problems of Rajasthan and Gujarat. He along with his associates is also engaged in research on anthropogenic and climate change impacts on Himalayan springs, particularly in Sikkim. He has worked also in international projects (funded by World Bank) on seismic micro-zoning through trench survey and active fault mapping in Kachchh, Gujarat. Currently, Dr. Bhuiyan is affiliated to Sikkim Manipal Institute of Technology, as Professor and Head of the Civil Engineering Department.
