Overview

  • My research is motivated by the rapid warming of our oceans. Broadly, we characterize the changes occurring in benthic (seafloor, including foundation and non-native species, and demersal fishes) communities using a combination of remote sensing (e.g., active acoustics (echosounders), unmanned aerial imagery, ground-truth, photogrammetry) and in-situ observations (diver surveys) and experiments. We study communities that span the deep sea to kelp forests and warm water coral reefs.

    This includes the study of changes in community composition, biogenic structure of reefs (temperate and coral), and relationships between bathymetry and species composition.
