I am an entomologist with special interests in prairie ecology and insect behavior, and have been teaching in the Department of Biology at Luther since 1993. Besides my family, I have a variety of other interests. One area of intellectual interest involves understanding the interactions between science and the Christian faith, especially the area of creation care, looking at our relationship to the environment and responsibilities as stewards of creation. I am a member of Decorah Covenant Church. For relaxation, I enjoy gardening, playing trombone, hiking, cross-country skiing, swimming and snorkeling, fly fishing, burning prairies, and eating ice cream.  In the summer I've taught Ecology, and still teach Entomology or Field Zoology at the Wheaton College Science Station in the Black Hills of South Dakota.

Active Research Projects:

Plant and Insect Communities in the US-52 Roadside Prairie Plantings. This project is funded by research grants from the Iowa Department of Transportation Living Roadway Trust Fund (LRTF). We are studying the impact of a roadside prairie planting project in Northeastern Iowa along US-52 from Decorah north to the Minnesota state line. This project started in the summer of 2008, is using butterflies and ground beetles as indicators of impacts of native plant species establishment.

Impact of Stream and Riparian Habitat Improvement on Aquatic and Terrestrial Insect Communities. In 2004, Dr. Michael Osterholm began a major stream restoration project in Waterloo Creek northwest of Dorchester, Iowa in Allamakee County. This project also involved establishment of native prairie in the riparian areas, and restoration of oak savanna in upland forests. Since 2005 we have been monitoring benthic macroinvertebrate communities in Waterloo Creek, Duck Creek, and Brook Creek on site, and comparing those communities to South Pine Creek, a high quality stream containing the only known remnant native population of brook trout in NE Iowa. We have also been monitoring ground beetle and butterfly communities in the prairie reconstruction and oak savanna restoration. Student research on this project has been funded by the M.J. McElroy Foundation, Dr. Michael Osterholm, and the U.S. Environmental Protection Agency.

Luther Gateway Prairie Reconstruction. In 2005, Luther planted a former field in the flood plain of the Upper Iowa River to tallgrass prairie with financial support from the Iowa DOT Living Roadway Trust Fund (the major donor), the Iowa DNR, Pheasants Forever, Luther College, and several private donors. Since that time, we have been studying ground beetles and butterflies as the prairie becomes established, and are monitoring the effects of flooding and fire in this prairie on these insect and the newly planted native plant communities. Student research on this project has been funded by Luther College and the U.S. EPA.
