Areas of expertise: Climate adaptation and mitigation, Small scale agriculture, Methane and nitrous oxide emissions, Mercury pollution, Nitrogen use efficiency, environmental microbiology, isotope geochemistry, biogeochemistry and biotechnology


Kritee is a part of EDF’s international climate team that is linking farmers to the carbon market in ways that promote mitigation, support development in the rural economy, accelerate poverty alleviation, and strengthen adaptation to the effects of climate change. She is helping lay the groundwork for agricultural carbon offset protocols for small land holdings by directing a multi-partner research team at the five GHG (nitrous oxide and methane) measurements laboratories across three states in Southern India. This research team is examining the effectiveness of innovative farming practices in delivering the three-fold goal of increased crop yields, better farm economics and decreased GHG emissions. She also provides scientific input to EDF's domestic legal teams’ efforts to improve government policies related to the energy sector, with a focus on mercury pollution from electric generation units.


Kritee gained postdoctoral experience on nitrogen cycling in the environment as a Camille and Henry Dreyfus post-doctoral fellow in Environmental Chemistry at Princeton University. Kritee also served as a Governor’s Executive Fellow at Eagleton Institute of Politics.
