I'm interested in understanding the impact of anthropogenically-mediated environmental changes on the community dynamics of aquatic organisms. That is, how do the various aspects of global change, including eutrophication, climate change, habitat fragmentation, and invasive species, affect primary producers and grazers in aquatic ecosystems? I use a combination of long-term monitoring, lab experiments, and meta-analyses to address these questions. I have studied interactions between invasive species and ecosystems, using zebra mussels, golden algae, and the invasive water flea, Daphnia lumholtzi as models. Harmful algal blooms, of both golden algae and bluegreen algae have been and continue to be a major focus of my work. My current work focuses on the interactions between bloom-forming cyanobacteria and their associated microbiome, investigating the facilitating and antagonistic role of the microbiome with cyanobacteria.
