Dr. Kourtev is a professor of Biology at Central Michigan University
Our lab investigates interactions between invasive species and microorganisms and how these interactions might facilitate the invasive process. We are also studying the assembly and stability of microbial communities in aquatic systems, using pitcher plants as a model. In the context of these two systems, we are particularly interested in how microbial community composition and function are related to each other.

Current Research Projects
I am interested in the the structure of microbial communities, how they are shaped by a variety of biotic and abiotic factors and how they are related to microbial community functions.
My applied research program has been in these areas:
- Microbial community in the rhizosphere of invasive plant species
- Interactions between microbial communities and toxic metals
- Microbial diversity in the gut of wild ruminants
- Microbial diversity in the pitchers of the Northern pitcher plant ( Sarracenia purpurea)
- Isolating previously uncultured bacteria
Research is currently being conducted in my lab to describe pollen grain diversity across the Brassicaceae. Trends in pollen evolution will be examined relative to recent advances in phylogenetic reconstruction and tribal classifications within the family. Pollen morphological data from scanning electron and light microscopy will be used to examine pollen evolutionary patterns and correlated floral evolution across the Brassicaceae.
