Current Research

My research focuses on the influence of habitat complexity, potential prey quality, and predator avoidance on resource selection in animals. I am particularly interested in marine invertebrate and fish utilization distributions in association with structurally complex and temporally heterogeneous marine systems, including Arctic under-ice environments, subarctic kelp forests, and tropical coral reef communities.
