Research Activities

• Determining the trophic and energetic strategies of deep-sea fishes using a variety of methods ranging from classic food habits analysis, to the development of high pressure vessels to work on these animals alive in the laboratory
• Examining the distributions and behaviors of deep-sea fishes using remotely operated vehicles (ROVs), submersibles, and autonomous camera systems
• Exploring the impact of mesoscale oceanographic features on the distribution, abundance and trophodynamics of the mesopelagic community
• Examining the use of marine protected areas to conserve deep water fish stocks and habitats

• OCN 627 - Ecology of Pelagic Marine Animals
• OCN 490,621 - guest lecturer
