I am a fungal biologist with an interest in evolutionary genetics.
My overall interest is in the evolutionary biology of fungi with a special emphasis on fungal reproductive biology and symbiotic associations. My work to date focused on one lineage of fungi known as arbuscular mycorrhizal (AM) fungi (Glomeromycota). Glomeromycota colonize roots of the majority of land plants, including many crop species, and form a symbiosis, in which the fungi assist plants in the uptake of mineral nutrients in exchange for plant-assimilated carbon. My short-term research goals are to understand several aspects of the basic biology of these organisms:
1. The reproductive biology and evolution of arbuscular mycorrhizal fungi.
2. The role of common mycorrhizal networks in the ecology and evolution of arbuscular mycorrhiza.
3. The role of bacterial endosymbionts in the biology of Glomeromycota and in the functioning of arbuscular mycorrhizae.
Outreach and Extension Focus
Arbuscular mycorrhizal fungi (Glomeromycota) facilitate plant mineral nutrient uptake and play an important role in the functioning of plant communities, both natural and managed. Because of this role in plant mineral nutrition, Glomeromycota hold a promise of becoming a substitute for chemical fertilizers.
My undergraduate teaching efforts center around evolution and ecology of mutualisms with a particular emphasis on microbial interactions. In my graduate-level teaching, I explore evolution of reproductive modes.
