I am interested in detecting the community changes and ecosystem resilience of lakes in response to anthropogenic disturbances and climatic change (especially the extreme drought events) through applying limnological and paleolimnology methods (i.e. diatoms, pigments, stable isotopes and geochemical proxies). My Ph.D. research is focus on identifying the effects of climate change, especially extreme events (drought, and deluge) on prairie wetlands over the past two hundred years by using paleolimnological approach in Cottonwood Lake Study Area, North Dakota, Southern part of Prairie Pothole Region.
