    My lab focuses on quantitative fisheries ecology, population dynamics, and fisheries stock assessment and management. We investigate interactions between anthropogenic and environmental drivers and dynamics of fisheries populations and ecosystems. We develop modeling frameworks to assess invertebrate and finfish stocks of commercial and recreational importance to aid management. We evaluate the importance of data quality and quantity in fisheries assessment and management, design and optimize fisheries-dependent and fisheries-independent monitoring programs, and develop management strategy evaluation frameworks. We evaluate impacts of climate change on dynamics of fisheries (e.g., habitat, fish distribution and life history, and fishing fleet dynamics) and ecosystems. We promote science-based management and international collaborations to improve fisheries management. Much of our work has been interdisciplinary. Our goal is to develop sustainable fisheries and ecosystem-based management, using an interdisciplinary approach of fisheries ecology, management policy, decision-making theory, mathematical and statistical modeling, and computer simulations.
