Research Focus I am a geologist specializing in Organic Geochemistry. The primary focus of my research is to decipher the ancient biotic forms and palaeo-ecosystems. In particular, I am interested in the organic molecular fossils (biomarkers) and stable isotopes preserved in sediments for unravelling a plethora of geochemical information spanning a diverse range of biota from microbes to complex flora and fauna and across the entire geological time scale. I trace the biotic origin and taphonomic alterations of organic matter in sediments using analytical geochemical tools and techniques. My research encompasses a combination of field work, laboratory analyses and data processing. I have been working on a wide spectrum of natural organic products such as crude oil, coal, carbonaceous mudrocks, fossilized flora and ambers sampled from different sedimentary basins in India. The various analytical techniques such as gas chromatography mass spectrometry (GC-MS), two dimensional gas chromatography time-of-flight mass spectrometry (GC×GC TOFMS), Rock-Eval Pyrolyzer, micro-Fourier Transform Infrared (FTIR) Spectroscopy, gas chromatography isotope ratio mass spectrometry (GC-IRMS) and multiple reaction monitoring (MRM) GC-MS have been employed for the acquisition of data. With the expanding database of organic compounds in soil and recent sediments, I am also using organic geochemical techniques for identifying pollutants and detrimental anthropogenic activities particularly in lacustrine ecosystems. |
