  • Research Scientist in the Department of Environmental Health Sciences
Profile Headshot


Anirban Basu is an environmental isotope geochemist. His research focuses on isotopic tracers of metal cycling in the environment and in biological systems. Metal stable isotopes record the chemical changes responsible for their environmental distribution and redistribution. His research has developed novel isotopic tracers to track cycling of toxic heavy metals, nutrients, and radionuclides. His current research focuses on developing metal isotopic biomarkers to understand health effects of metals and quantify exposure. Metal isotope analysis uniquely reveals the molecular mechanisms of metal-organic reactions employed by cellular biochemistry. This metal’s eye view of metal-organic interactions from isotopic composition of biological samples (e.g., blood, urine) is a powerful tool to probe accumulation of metals in human body, disruption of metabolism and disease development, and is a key to develop reliable non-invasive biomarkers of metal exposure.
