Prosun Bhattacharya (1962), Professor of Groundwater Chemistry and Coordinator of the KTH-International Groundwater Arsenic Research Group at the Department of Sustainable Development, Environmental Science and Engineering at KTH Royal Institute of Technology, Stockholm, Sweden. holds a PhD in Sedimentary Geochemistry from University of Delhi, India (1990). Besides KTH, he also holds an Adjunct Professor at University of Southern Queensland, Australia between 2016 and 2019. Since January 2020, he is appointed as Affiliate Scientist at the KWR Watercycle Research Institute in the Netherlands and working with the challenges with arsenic, fluoride and geogenic contaminants in drinking water treatment systems. His research interests are primarily in the field of drinking water contamination from groundwater sources in different parts of the world, especially focusing on geogenic contaminants – arsenic and fluoride. He has collaborative research engagements with several universities and research organizations across the world. He is leading the Sida funded bilateral Research Capacity Building programs between Sweden and Tanzania as well as Sweden and Bolivia, focusing on drinking water contamination from groundwater sources and treatment. He has coordinated the prestigious Swedish International Development Cooperation Agency supported action research and implementation project “Sustainable Arsenic Mitigation-SASMIT” Community driven initiatives to target arsenic safe groundwater as sustainable mitigation strategy in Bangladesh (2007-2017). He is currently leading a project on “Enhancing private sector capacity for scaling up access to safe drinking water - policy, systems strengthening and sustainable service delivery” in collaboration with UNICEF-Bangladesh.

He has authored/co-authored over 500 international publications in peer-reviewed journals and conference proceedings, cited more than 13,400 times (Google Scholar and Google h-index 55) and i10-index of 167. He has organized several international workshops on natural arsenic in groundwater and sustainable mitigation and edited 11 books on diverse aspects of natural arsenic in groundwater and groundwater for sustainable development until 2019. He is serving the Elsevier in the different editorial capacities since 2009, as Editor in Chief of Groundwater for Sustainable Development, and Associate Editor of the two reputed journals Journal of Hydrology and Environment International. He has been honored as the Fellow of the Geological Society of America in April, 2012 and the International Water Association (IWA Fellow) in September 2018. Recently he has been conferred with the “STE International Achiever Award, 2019” by the Save the Environment Foundation in recognition of his distinguished work in the field of Environmental Geochemistry and Water Quality Analysis as well as the widely acclaimed research on groundwater management has triggered path breaking research and several projects and your scientific accomplishments. Since March 2020, he is actively working with the global initiative on the wastewater based epidemiology as a global collaborative effort to maximize contributions in the fight against COVID-19 which involves the academic, government, research institutions and the Community based organizations.
