My research is driven by my interest in improving the current understanding of the transformation of the environment and ecosystems under the influence of increased greenhouse gas emissions and other anthropogenic stresses. As present is key to the past, I extend the knowledgebase thus generated to address past environments.

To achieve this, I employ a combination of conventional and innovative stable isotope techniques. My research has contributed to the establishment of stable isotope ratios of carbon and oxygen in rice as a proxy for relative humidity levels, and its application to archaeological rice remains for reconstruction of palaeo-hydroclimate conditions at the sites of Harappan civilization. Furthermore, I have employed the multiple isotope approach for determination of nitrate dynamics in a freshwater reservoir and investigations into the processes responsible for N2O emissions from arable soil treated with varying levels of N-fertilizers.

Currently, I am investigating biosphere-atmosphere interactions over a semi-arid Mediterranean Pine forest by combining eddy covariance with hyperspectral remote sensing.
