Research Interests

I’m interested in the effects of chronic toxicant exposure in freshwater plankton communities. I use pollution-induced community tolerance (PICT) to evaluate shifts in community structure over time. I’m particularly motivated by the heavy use of copper sulfate (CuSO₄) as a treatment for harmful algal blooms and the potential development of resistant communities.

When I’m not in the lab, I spend my time hiking in the Auburn area with my beagle, Magnolia.
