Research Interest:<\/h3>\n\n\n\n

I am highly interested in the biogeochemistry of freshwaterecosystems. In particular, the influence of nutrient stoichiometry on plankton communities and methane dynamics in Lake Geneva. The microorganisms of an ecosystem interact with each other in the biogeochemical cycling of carbon, nitrogen, and phosphorus (C, N, P). Thus, I focus on studying freshwater lakes to elucidate the stoichiometric balance of theseelements and dictate the structure of planktonic microbial communities, thereby controlling the greenhouse emissions infreshwater lakes. I also predict that the human-induced nutrient enrichments might impact the ecophysiology of microbial communities under the predicted climate change scenario, and subsequently may influence the environmental changeslike aerobic production of methane. Therefore, I have always found aquatic ecology exciting to identify how different microbial communities respond to such environmental challenges and to mitigate climate change as well as protect Earth’s ecosystems.<\/p>\n\n\n\n
