Research Interests:

My research is broadly focused on applied ecology embedded within a framework of answering theoretical questions to better understand and manage aquatic ecosystems. My general research interests are centered on the context of describing how the environment influences fish population dynamics and how that information can be used to better manage our natural resources. My research program has varied among types of systems and species of fish, but has primarily focused in riverine environments. I am interested in determining how both native and introduced fishes use riverscapes with varying levels of connectivity or are impacted by other anthropogenic features
