Research interests: I am a restoration ecologist. In our laboratory,  our studies include ecology of garlic mustard (Alliaria petiolata) an invasive plant, impact of deer browsing on native vegetation, historic vegetation, prairie restoration, the effect of fire on  vegetation, and the ecology of mycorrhizae.
