Welcome!

A vibrant research and teaching program in forest entomology has been a long hallmark of the U, from Sam Graham (1921), Leslie Orr (1927), and Alex Hodson (1931) to Herb Kulman (1966), Steve Seybold (1998), and Peter Rush (2002).

Our research group (est. 2010) studies the ecology of forest insects, linking patterns across space and through time to individual- and community-level processes. We work across plant-insect and predator-prey interactions, landscape ecology, population dynamics, chemical ecology, and biometry, the application of statistical tools to novel ecological questions therein. Linking pattern and process across scales touches on a number of topics in resource management, such as insect outbreaks and disturbances, dispersal, sampling, changing climate, invasion biology, and biological control.

Our research program is based on the St. Paul campus of the University of Minnesota, where I hold a McKnight Land-Grant Professorship in the Department of Entomology.
