The overarching question of our research group is to understand 1) what shapes the variability and viability of populations and communities in highly variable environments and 2) how to use such information to build models and insights that result in a more just, equitable, and sustainable future.

To address these objectives we study how processes such as competition, food limitation, Allee effects, and metabolism interact with climatic variability and human harvest to shape spatial and temporal variability in the dynamics of marine fish, invertebrates and algae.   Our research relies on statistical and mechanistic modeling approaches to integrate theory with fieldwork, monitoring data, and laboratory experiments.   Finally, our work is focused on developing insights and quantitative frameworks that can directly affect how natural resource management and conservation can lead to more verdant ecosystems and societies.

In our work we partner with specialists in fields ranging from ecophysiology to natural resource governance and work directly with communities, First Nations, and government agencies.
