As director of the University of Wisconsin Trout Lake Station, I welcome inquiries about the use of station facilities for research projects. 

My research interests include the long-term, regional ecology of lakes; metabolism and carbon dynamics of lakes; land-groundwater-surface water interactions; global patterns in lake dynamics through development of Global Lake Ecological Observatory Network (GLEON).
