Ryan-SharkLab-Staff

Dr. Ryan Logan

Master's Degree: California State University Long Beach (2017)

Doctorate Degree: Nova Southeastern University (2023)

Research Interests: Dr. Logan is interested in the movements, behavior and ecology of coastal and pelagic sharks and gamefishes to better implement species management and ecosystem conservation measures. Using a variety of technologies and techniques, his PhD research investigated the post-release recovery behavior, fine-scale hunting patterns, and ecological niche partitioning of a large pelagic predator guild in the eastern tropical Pacific, including blue marlin, black marlin and sailfish. His current research seeks to identify how drivers of movement vary across ontogeny within the southern California white shark nursery.

Dr. Thomas Farrugia

Dr. Thomas Farrugia

Master's Degree: California State University Long Beach (2010)

Doctorate Degree: University of Alaska Fairbanks (2017)

Research Interests: Dr. Farrugia is interested in the ecology, behavior and life history of elasmobranch and teleost fishes, and in their implications on fisheries management. His PhD research was an interdisciplinary analysis of the skate fishery in the Gulf of Alaska which integrated movement patterns, population dynamics, bioeconomics and nutritional analysis of big and longnose skates. He started his current research on the Northeast Pacific population of white sharks in 2019 with both CSULB and the Monterey Bay Aquarium.

Dr. James Anderson

Master's Degree: University of Hawai'i at Mānoa (2017)

Doctorate Degree: University of Hawai'i at Mānoa (2018)

Research Interests: Dr. Anderson is interested in the sensory biology, ecology and behavioral ecology of elasmobranchs and other fishes. His Ph.D. research focused on the perception and use of magnetic fields in elasmobranch navigation behaviors. His current research focuses on understanding the drivers of movement behaviors and habitat use of juvenile white sharks along the California coast.

Dr. Kady Lyons

Master's Degree: California State University, Long Beach (2013)

Doctorate Degree: University of Calgary (2018)

Research Interests: Dr. Lyons is interested in studying maternal contaminant offloading in elasmobranch fishes and the implications that has for health and fitness. She also is interested in understanding factors that affect contaminant accumulation and thus species exposure to anthropogenic chemicals and how that changes over ontogeny.
