Matt Bogard, PhD

Postdoctoral Fellow

I am a postdoc in the Butman lab working primarily on defining the rates, patterns, and sensitivity of aquatic carbon cycling in lakes and streams of the Yukon River Basin.  My project is directly linked to the broader NASA-ABoVE research program, and the project (PI:Rob Striegl, USGS) “Vulnerability of inland waters and the aquatic carbon cycle to changing permafrost and climate across boreal northwestern North America”.  

Working with colleagues here at the UW, the USGS, University of Regina, and Florida State University,  my work centers around 2 major themes: First,  I want to assess the sensitivity of metabolism, organic matter cycling and greenhouse gas emissions in lake in the Yukon River Basin (Alaska/Canada) to changing climatic and hydrologic conditions. Second, I want to characterize permafrost thaw effects on organic matter age and composition in aquatic networks, both spatially along a gradient of terrestrial-aquatic connectivity (from seeps to streams to lakes) and also back through time (paleolimnological reconstruction of organic matter storage in a set of hydrologically diverse lakes).  

My previous work has focused on boreal lake carbon cycling during my PhD with Paul del Giorgio (Universite du Quebec a Montreal), aquatic nitrogen biogeochemistry, pollution and water quality degradation during my MSc with Peter Leavitt (University of Regina), as well as lake phosphorus cycling and climate-driven salinization of prairie lakes during my BSc with Jeff Hudson (University of Saskatchewan).
