R.V. Krishnamurthy

Dr. R.V. Krishnamurthy is professor of stable isotope geochemistry in the Department of Geological and Environmental Sciences at Western Michigan University. His research emphases are stable isotopes, paleoclimates, carbon cycling in freshwater systems and geochemical fate of contaminants. Krishnamurthy leads a research team focusing on stable isotope research, emphasizing the use of carbon, oxygen and hydrogen isotopes to investigate a variety of environmental and geochemical problems. He supervises the Stable Isotope Laboratory at the Department of Geological and Environmental Sciences. This group pioneered the application of hydrogen isotopes in sedimentary organic matter as a climate proxy and developed analytical techniques to extract dissolved organic carbon compounds in water samples for isotopic measurements as well as techniques for carbonate analysis.
