Danielle Haulsee is the Chief Science Officer at Hubbs-Seaworld Research Institute, specializing in fisheries oceanography and the spatial and behavioral ecology of marine animals. She obtained her Ph.D. in 2017 from the University of Delaware’s College of Earth, Ocean, and Environment, focusing her doctoral work on characterizing the movement ecology and social dynamics of a coastal top predator found along the East Coast of the U.S., the sand tiger shark. A key feature of her research is integrating advanced bio-logging (using tags carried by animals to record information), remote sensing and underwater robots to study the impact of a dynamic ocean on the occurrence and distribution of marine fish and sharks. Using these technologies, Danielle focuses her research on tackling applied research questions, contributing to bycatch reduction strategies, impact assessments of offshore wind development, and working towards more effective dynamic ocean management strategies. Her work spans multiple oceans, from studying the movement ecology of sharks and sturgeon in the Atlantic, to the fisheries ecology of billfish in the Eastern Tropical Pacific, to the oceanography of the White Shark Cafe in the Central Pacific and off of the Nansen Ice Shelf in Antarctica.

Danielle oversees the science program at HSWRI in our main location in Mission Bay, CA, our hatchery in Carlsbad, CA and our Florida office in Melbourne Beach. She is a member of the American Fisheries Society (AFS) and The Oceanography Society (TOS), as well as a contributing member of the Diversifying and Integrating Marine Education at Stations (DIMES) and Ecosystem Services Observation Network (ESON) initiatives on the West Coast. In addition to her research, Danielle is passionate about mentorship and promoting STEM education to underrepresented groups through her participation in organizations like the Society for Women in Marine Science (SWMS), the Gill’s Club, the Skype-a-Scientist program, UD’s Mentor Collective Program, as well as serving as a mentor for many other high school and undergraduate student internship opportunities.
