The overarching question of our research group is to understand 1) why and when populations exhibit stability versus volatility in highly variable environments and 2) how to incorporate such information into trade-off analysis that are relevant to both human and ecological communities.

To address these questions 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 field and laboratory experiments, field surveys.   Ultimately, our work is focused on integrating such understanding into quantitative frameworks that highlight trade-offs in management and conservation.

General Research Areas: 

  • Quantitative population dynamics of marine organisms
  • Fisheries management & conservation
  • Statistical & Bayesian methods in biology, ecology & fisheries
  • Marine community ecology
  • Trophic ecology, metabolic scaling and physiology
  • Reproductive biology and phenology
