Research

"Stable Isotopes in nature and in the laboratory" sums up my research interests. I apply known stable isotope techniques to geochemical, hydrological and related environmental studies and also go hunting for new and novel applications. Presently, I am involved in the study of lake sediments to understand paleoclimate and in ground water to understand various biogeochemical and hydroclimatologic processes. I also spend time in developing techniques that will make a stable isotope geochemist's life a bit easy, and look for collaborative research. We have developed simple techniques for the extraction of dissolved inorganic carbon in water samples and for the analysis of carbon and oxygen isotopes in carbonates (see publication list). Collaboration at present involves Dr M. Baskaran (Wayne State University), Dr Navin Juyal (Physical Research Laboratory). The stable isotope laboratory under my direction is equipped with a Micromass Optima isotope ratio mass spectrometer, various vaccum extraction lines, constant temperature bath and a microwave sample digestion system.
