Research Interests
I study food web ecology through the lens of trophic dynamics and movement ecology, which establish links among humans, animals, plants, microbes, and the environment. I am interested in building a quantitative, mechanistic understanding of how consumer-resource relationships build the food web architecture that supports ecosystem function. I am particularly interested in how how natural and anthropogenic interactions affect resource utilization, carbon flow pathways, and trophic structure in coastal ecosystems. My research uses a multidisciplinary approach that draws upon expertise in ecology, oceanography, biochemistry, and geochemistry.  Much of my research is based on the development and application of cutting-edge analytical tools, such as compound-specific stable isotope analysis (CSIA) combined with advanced statistical modeling. Through controlled feeding experiments I develop a quantitative understanding of the biochemical and physiological mechanisms that support resource acquisition and allocation. I apply this knowledge in large scale field studies to examine a wide range of questions from individual nutritional ecology, to population connectivity, all the way up to entire ecosystem food web dynamics. My research is highly collaborative, engaging partnerships across academia, local/regional governance, and invested stakeholders to enhance both our research capacity, and the effectiveness of coastal management. My research program is firmly rooted in fundamental ecological theory, but extends beyond the ecological questions to the applied management and practical decision-making needed to resolve current and emerging coastal ocean challenges.
