I am a population and community ecologist primarily focusing on freshwater systems. Broadly, my work explores the effects of drought and other stressors across multiple ecological scales in streams. To address these topics, I use a mix of quantitative modeling and experimentation. My postdoc research has examined questions around stream macroinvertebrate metapopulation dynamics, estuarine food web dynamics, and climate-driven phenological change.
