I received my PhD in Atmospheric Science, focusing on understanding local-regional scale variability in climate, with an emphasis on the processes that involve deep convection and impact the hydrological cycle. My research includes study of atmospheric circulation and how it responds to or is projected to respond to anthropogenic forcings. I address these issues through numerical models, including General Circulation Models and Mesoscale Meteorological Models.

In my recent work at LLO, I am interested in surface heat fluxes on the Great Lakes, particularly evaporative fluxes and their temporal and spatial structure on Lake Superior. To that end, I use numerical model simulations and available direct measurements.

I am interested in factors that structure wetland and coastal land-margin ecosystems. My research focuses on the roles that nitrogen and phosphorus play in organizing biological communities at the base of Great Lakes coastal food webs. I use a variety of field and laboratory techniques to measure nutrient bioavailability including, bioassays, in situ nutrient amendments, and physiological indicators of nutrient limitation.

My recent work characterizes the biogeochemical transformations and measures shifts in planktonic communities along the gradient formed as the water of the St. Louis River, rich in dissolved organic matter, enter the clear water of Lake Superior. In addition to measuring algal communities and nutrient transformations, I am also beginning to investigate the interactions between CDOM and nutrient biogeochemistry along this river-to-lake gradient and developing an understanding of how these ecosystem processes may be affected by changing climate and land use patterns.

I am primarily interested in learning and sharing a basic understanding of ecosystem services and the economic values associated with these services. Conducting such research is challenging, however it is equally important to know the trade-off of losing our ecosystems in monetary values. Working on the Great Lakes ecosystem is itself a very good opportunity to expand the ecological economics paradigm of research.

I have a varied research experience ranging from community development, agricultural economics, forestry economics, and biodiversity conservation. I have around ten years of professional experience in participatory natural resource management and sustainable rural tourism development in Nepal.

Lakes respond very sensitively to regional environmental changes. Sediments accumulating on their bottom record these changes, in some cases over millions of years. By drilling into the lake bottom and recovering these natural archives we shed light onto past climate and furthermore might be able to find answers about possible linkages between climate and our evolution.

I use basic sedimentological tools to understand sediment deposition next to a suite of proxy records extracted from lake sediments to reconstruct past changes in environmental and climate conditions at annual to centennial time-scales since the Pliocene. My primary research areas are located in Turkey (ICDP project PALEOVAN) and the East African rift valley (ICDP project HSPDP). Turning lacustrine mud into information; e.g. the ability to reveal the lake´s history and it's response to climate change, fascinates me.
