Professional Interests:

I am a Sedimentary Geochemist and Paleolimnologist, and I apply geological and geochemical methods to study past climate and environmental change. I am currently working with undergraduate students and collaborators at UST, the University of Minnesota, The St. Croix Watershed Research Station, and Macalester College on research projects involving the collection and analysis of lake sediment records from several different settings.  

Research Interests:

Holocene paleoclimatology and paleohydrology: My research has focused on Late Holocene records from small lakes that provide local to regional signals.  Current areas of interest are in the Great Basin region of southern Nevada and the Patagonian Andes of South America.  I apply sedimentology and geochemical methods including elemental and stable isotopic analysis of C, N, and O in lacustrine organic remains and carbonates. 

Paleoecology and carbon burial in shallow lakes:  Small shallow lakes and wetlands are now recognized for their significance in the global C cycle.  My collaborators and I are exploring past and present C dynamics using a variety of biogeochemical methods in the Prairie Pothole region of west-central MN.

Climate change education, attitudes, and misconceptions: I have an ongoing project exploring student thinking about the challenges posed by climate change through polling, direct and open-ended questioning, and interviews.
