My research focuses on the diversity and spatial structure of the epibenthic megafauna in the deep waters of the Gulf of Maine (northwest Atlantic). Megafaunal communities in this region are comprised of deep-water corals, anemones, sponges and echinoderms.
I am interested in the influence of habitat complexity on diversity patterns at various spatial scales: from the micro-scale of recruits to 10s of kilometers covering the Gulf of Maine.
