  • Name: SOURAV GANGULY
    Year of joining: 2016

    Research interest:

    Broadly I am interested in understanding earth system processes using geochemical tools, specifically stable isotopic methods for which I employ both field and laboratory based investigations. The primary aim is to look at palaeoclimatic variability using several stable isotope proxy data. I also intend to look at global carbon dynamics in Earth systems and present day climate variability using geochemical observations on several attributes. Other aspect of my research is to develop stable isotope techniques to better understand evolutionary palaeobiology. I also have a parallel interest in understanding energy policies that can lead to sustainable development.

    Year of joining: August 2012

    Research interest:

    I am a PhD Student and I am working on computational Chemistry and its application to natural samples. We are using quantum chemistry and ab-initio methods to find the different modes of vibrations of molecules. For that we mainly used ‘Gaussian09’ package. We use the frequency values to find the amount of fractionation and its variability due to different temperatures in the past.

    Another work is the effect of Catalyst allowing randomization of CO2 molecules at different temperature; also described as Savatier effect in metal–gas interaction. We proposed a study of reaction mechanisms between catalyst (Pt) and CO2 by means of DFT calculations, which represent a bridge bond between the theoretical calculations and the processes seen in the experiment.

    Year of joining: 2014

    Research interest:

    Stable isotope and clumped isotope thermometry of carbonatites and carbonate melts. The objective is to determine the temperature of crystallization of calcite within the igneous carbonates and also involves detailed mapping of the carbonate phases using micro Raman, electron microprobe and all other suitable analytical techniques.

  • studentsName: Himanshu Bhagat
    Year of joining: 2010

    Research interest:

    My research background is in ecological sciences but over time I have developed a strong interest in Multidisciplinary sciences. Stable isotopes offer an immense opportunity for probing the dynamics of natural and anthropogenic systems along with determining their origins and source. My research involves measurements of stable isotopes (18O, 13C) of river water in the Cauvery basin and its tributaries. This will assist in addressing important questions pertaining to seasonal variability including the influence of the SW and NE Monsoons on river water. GIS will be used in preparation of Isoscape maps of the entire basin. Additionally the project will investigate the influence of irrigation waters on Vitis vinifera by measuring the isotopic values of different plant components (stem, leaves, buds and berry) including the processed plant product. This will help quantifying the excursions of isotopic values of plant components as compared to irrigation water as well as ascertaining the crucial factors and reasons at play. Excluding research and if time permits, I am passionate about macrophotography and trekking. I believe in seeking out new experiences in all aspects of life.
