My research is driven by a deep interest in understanding how environments and ecosystems transform under the influence of global warming and other anthropogenic stresses. Building on the principle that the present is key to the past, I also extend these insights to reconstruct and interpret past environmental conditions.

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