Broadly, I am interested in the impacts of human stressors on vulnerable wildlife and human communities. The former subject is explored by my research on the effects of hydroelectric dams on freshwater biodiversity in the tropics. The latter subject is explored by my research on the linkages between industrial land use change and socio-demographic disparities in the U.S. through the lens of freshwater systems. I utilize large datasets to discern patterns across space, time, and taxa. Understanding these relationships is vital to develop applied science that can directly inform managers, stakeholders, and policymakers.
