I am interested in understanding biosphere-climate interactions for applications in both modern and ancient contexts. 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 to address modern day environmental questions, such as the determination of nitrate dynamics in freshwater and investigations into the processes responsible for N2O emissions from arable soil treated with varying levels of N-fertilizers.
