My research explores biogeochemical connections between land and water at landscape to macrosystem scales. I use a combination of field/lab methods, satellite remote sensing, and GIS analyses to learn about streams, lakes, rivers, and estuaries. My CV is available here.
DISSOLVED ORGANIC MATTER IN ARCTIC RIVERS
In the Arctic, my research uses satellite remote sensing and laboratory analyses to address two questions: Where does riverine organic matter come from? And how are OM dynamics changing in response to climate?
REMOTE SENSING OF WATER QUALITY IN TEMPERATE LAKES
Using remote sensing products , I am looking for trends in lakes DOM across Minnesota, associated with climate, atmospheric chemistry, and land use. I also am examining watershed controls on lake CDOM in three ecoregions of northern MN, WI, and MI.
STORM-DRIVEN NITROGEN EXPORT TO TEXAN ESTUARIES
Nitrogen from agricultural run-off and wastewater is a major driver of estuarine ecosystems. In coastal Texas, alternating wet-dry years results in large variations in nitrogen delivery from rivers.
