Anirban Basu is an environmental isotope geochemist specializing in groundwater chemistry, metal contamination, and their impacts on human health. He is currently a Research Scientist in the Department of Environmental Health Sciences at Columbia University’s Mailman School of Public Health. As Principal Investigator of Project 2 in Columbia’s Northern Plains Superfund Research Program, Dr. Basu leads water quality research to monitor metal exposure in rural and tribal communities near Superfund sites and abandoned uranium mines. Dr. Basu’s research is highly interdisciplinary, integrating geochemistry, environmental science, and public health. His current work focuses on developing metal isotopic biomarkers to quantify human exposure and understand the health effects of toxic metals. By analyzing the isotopic composition of biological samples such as blood and urine, his research provides insights into metal accumulation, metabolic disruption, and disease development—advancing non-invasive approaches to exposure assessment. Prior to joining Columbia, Dr. Basu was Associate Professor in the Department of Earth Sciences at Royal Holloway, University of London.
