Research interests
Marine and freshwater communities can change rapidly, with previously dominant species suddenly collapsing, and previously rare or absent species exploding in numbers. I'm fascinated by what drives these rapid changes, how to detect and measure them as they occur, and what roles human activity, environmental variability, and variability in how different species use space play in causing or resisting change.
Our team uses long-term ecological data and statistical, computational, and theoretical tools to understand what causes ecological change in fished communities. We also develop new statistical approaches and adapt and refine existing methods to improve how we monitor and detect long-term ecological change across scales, from small lakes to whole oceans.
