Research

Marine and freshwater communities can change rapidly, with once-dominant species suddenly collapsing and previously rare or absent species exploding in abundance. My research focuses on understanding the causes (both human and natural) of these rapid shifts, detecting them as they occur, and understanding the role that spatial variation in species interactions and diversity of movement capacity plays in shaping how resilient fisheries are to these shifts. I use long-term data sets, mathematical and computer models, and modern statistical techniques to better understand these complex systems.
