Research Interests

In general, I am broadly interested in animal ecology, diversity, and behavior and students have worked with a wide variety of organisms in my lab, from mice to snakes.  However, students generally focus on some aspect of spider behavior or ecology, often working with the brown recluse spider.  I am interested in the distribution and natural history of this spider in Illinois and Iowa and have set up a web page to collect data from the general public, the Brown Recluse Project.

Students have worked on foraging behavior of recluses including studies on their preference for live or dead prey and the possible use of olfaction in locating dead prey.  Also, we have investigated temperature tolerance in brown recluses.  Many other projects on the behavior and ecology of this species are waiting to be done!  Other students have worked with various orb-weaving spiders to investigate some of their behaviors such as constructing a stabilimentum or web-shaking.  Prey choice and learning in jumping spiders is also a subject for exploration. Studies of spider diversity in different habitats such as restored and virgin prairies also hold great potential for research.
