 Research Interests

My research interests intersect the basic and applied fields of aquatic ecology and fisheries management. I am particularly interested in conducting research that combines empirical approaches (lab or field) with quantitative and modeling approaches to investigate processes regulating fish populations and communities. An overarching goal of my research is to generate novel ecological knowledge that can inform applied management needs. Along these lines, much of my research has focused on understanding how ecological stressors (i.e., climate change, hypoxia [aka “dead zones”], salinity exposure) affect fish populations, and subsequently, impact management of aquatic resources.
