I am 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). My research interest is in the field of drinking water contamination from groundwater sources in different parts of the world, especially focusing on geogenic contaminants – arsenic and fluoride. I have collaborative research engagements with several universities and research organizations across the world. I am 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. I have 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). I am 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.
Awards and Professional distinctions:
Fellow of the Geological Society of America (April, 2012)
International Water Association (IWA) Fellow (September 2018)
“STE International Achiever Award, 2019” by the Save the Environment Foundation "in recognition of 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 scientific accomplishments" (October 2019).
TU Delft Global Drinking Water Best Paper Award 2019 (November 2019)
The winning paper " Sediment color tool for targeting arsenic-safe aquifers for the installation of shallow drinking water tubewells" (in Science of the Total Environment, 493: 615-625) was awarded the prize with the motivation that it "was regarded as very complete, scientifically relevant, original and above all, highly useful in practical terms. Furthermore, it was the only publication which made it to the top 4 of all jurors".The awarded paper originates from the Sustainable Arsenic Mitigation (SASMIT) project. Sida has published the project as one of its result examples (Sida.se: Method will reduce arsenic poisoning in Bangladesh).
Awarded the George Burke Maxey Distinguished Service Award 2021 Presented annually, the award recognizes exemplary service "to the hydrogeology profession and to the Hydrogeology Division, Geological Soceity of America".
