Research Interests:
All organisms are colonized by microbes, though only by a small subset of the microbes to which they are exposed. What determines which microbes can colonize and live within an organism? My research addresses this question from an ecological and evolutionary perspective using two host systems: 1) Squash bugs (an agricultural pest) and other, closely-related true bugs, and 2) the model social amoeba, Dictyostelium discoideum. Both of these hosts acquire beneficial bacteria from the soil and I use microcosm studies, next-generation sequencing, and fitness assays to understand how those bacteria contact and colonize hosts when other bacteria cannot.

Research Interests:
I am an ecologist interested in experimental and empirical tests of theory in community ecology, specifically theories that address the mechanisms generating community composition, coexistence, and the maintenance of plant and microbial diversity. Specifically, I conduct laboratory, field, and greenhouse experiments to evaluate the effects of fungi and bacterial communities on plant hosts, and how these interactions may build up to mediate plant communities as well as ecosystem processes at larger scales.

Research Interests:
My research interests are in the toxicology of environmental metals and their impacts on human health. Specifically, I am interested in understanding mechanisms of metal-induced toxicity to hematopoietic stem and progenitor cells, including the hematotoxicity of inorganic and organic arsenicals. My other major research interests are in elucidating mechanisms of immune dysregulation produced by metal exposures.
