Welcome to the Conservation Biology and Avian Ecology homepage.  My research and teaching are focused on understanding how human activities influence animal and plant populations.  Most of my research involves birds in one way or another although I have worked with insects, plants, deer, bats some amphibians.  My graduate students, post-docs and undergraduates in the lab have worked in many parts of the upper Midwest as well as Hawaii, Costa Rica, Mexico, Argentina, and Brazil.
