Research and Professional Interests:
We study population dynamics, with a focus on how environmental variability, trophic interactions, and management affect population viability and productivity in space and time. We partner with coastal and Indigenous communities, with the goal of using research to make fisheries and conservation more equitable, ecologically sound, and just. Research in the lab integrates field & laboratory experiments, field surveys, statistical analysis, quantitative theory, and simulation modeling.
