We investigate the causes and consequences of biodiversity change in marine ecosystems, with the goal of developing science-based tools to inform conservation and restoration under global change. Our lab uses a range of methods including field experiments, theoretical and statistical models, studies along environmental disturbance gradients, and stakeholder surveys to understand how drivers like biological invasion, climate change, and harvesting are altering the structure and function of aquatic ecosystems and the goods and services they provide to people. We also pair ecological and social science approaches to understand the consequences of conservation and restoration interventions for coupled human-natural systems. Our projects feature strong partnerships with practitioners and local community members to ensure that the co-developed research addresses practical information needs as well as intriguing scientific questions.
Unprecedented rates of global climate change are now pushing species’ ranges and densities far outside historical variation. How will ecosystems and the resources we derive from them respond? Our research is tackling this issue by investigating the organismal role traits (behaviour, morphology, physiology, and life history) play in determining the strength of interactions within marine food webs. Our ultimate goal is to predict ecosystem structure and function under future global change scenarios that account for the important influence of species interactions on ecological outcomes. A core project in this theme focuses on the effects of climate change on the distribution of predatory Albacore tuna in the California Current Large Marine Ecosystem and the consequences for cross-boundary fisheries in collaboration with scientists at NOAA Southwest and Northwest Fisheries Science Center, Stanford University, and Scripps Institute of Oceanography.

Precipitous declines in coral reef and mangrove habitat worldwide threatens the food security, livelihoods and infrastructure of tropical coastal communities. Is it possible to restore the functionality of damaged habitats? What ecological and socioeconomic factors mediate the success of restoration efforts? Our research is tackling these questions through research in collaboration with coral restoration organizations and coastal managers in the Caribbean Sea where restoration is occurring amidst a range of other conservation interventions. By applying a range of ecological concepts including resilience, functional connectivity, and metacommunity theory to field and modeling studies from local to seascape scales we are investigating the context in which restoration interventions are likely to lead to ecological recovery and socioeconomic benefits.

Predicting the effects of biological invasions on ecosystems and the natural resources they provide is a top challenge for conservation. In aquatic ecosystems, restricted access to many habitats and high population connectivity mean that invaders spread at a pace and scale that often precludes complete eradication. To tackle this issue, we are building tools that help managers forecast the consequences of invasion intensification and spread, and decide how to best use resources to prevent and reverse the impacts of invasion in aquatic ecosystems. Pertinent questions that our work asks are:
Current research in our lab addresses these questions through collaborative research on three broadly distributed invasions of management concern: Indo-Pacific lionfish in the tropical Western Atlantic, European green crab in the eastern Pacific, and Prussian carp in central Canada.

We seek to understand the feedbacks between social and ecological processes that fuel sustainable systems, forming partnerships beyond ecological science to understand how interventions such as market development, volunteer engagement, and media communication play a role in durable solutions to pressing conservation problems. We also seek opportunities to generate reflective insights into the ways that societal sectors can effectively engage in co-developing research that generates relevant knowledge for management and conservation.
