Monday 10:30-11:30am; Thursday 8am-10am

Between classes and labs I am typically in my office, feel free to stop by.


I joined the faculty at UW-Baraboo/Sauk County in Fall 2013 after completing a post-doctoral appointment at Oak Ridge National Lab. Prior to that I was at Colorado State University working towards my MS and PhD in Ecology. My research interests focus on how soil microorganisms respond to changes in temperature and moisture. Microbes are the drivers of processes in soils and are a fascinating area of research because the organisms themselves are so small but their impact on the soils system is monumental.

Teaching philosophy: "Education is not the filling of a pail, but the lighting of a fire." ~William Butler Yeats

Outside of the lab and classroom I enjoy hiking and reading.
