Research areas

I'm an ecologist and conservation biologist interested in species interactions, especially those involving insects and plants. So far, I have worked on basic and applied questions related to the ecology of early-instar caterpillars, the role of plant chemistry in trophic interactions, and the ecology of hemiparasitic plants.

Much of my research is designed to assist or inform on-the-ground conservation. During my PhD work, I collaborated with several conservation agencies and organizations to help inform grassland management and recovery of threatened and endangered species.

I lead two research projects in the Landis lab:

  • As part of the Great Lakes Bioenergy Research Center, we are forecasting effects of bioenergy cropping on insect communities and the ecosystem services they provide in the Midwest US. Demand for bioenergy crops is likely to change landscape composition and spatial configuration in our region; depending on the crops and practices that are adopted, this could be either beneficial or harmful to the insect communities we rely on for pollination and control of crop pests.
  • Monarch butterfly conservation. We are testing how ecological disturbance influences predation on monarch eggs and larvae, and the suitability of monarchs' milkweed host plants.


I did my PhD, and a short postdoc, at the University of Washington School of Environmental and Forest Sciences in Seattle. I completed an M.S. at the University of Michigan School of Natural Resources and Environment, and B.S. in biology at Calvin College.
