Joshua Stewart

Joshua Stewart is Assistant Professor and Principal Investigator of the Ocean Ecology Lab at Oregon State University's Marine Mammal Institute. His quantitative ecology research focuses on threatened marine species, integrating movement tracking, population modeling, and conservation applications.

Research domains:

• Elasmobranch (manta ray, shark) ecology
• Marine megafauna conservation
• Fisheries interactions and bycatch mitigation
• Population dynamics modeling
• Climate change impacts on marine predators

Publications emphasize Bayesian statistics for spatial ecology and population assessments. Recent work demonstrates strong focus on human impacts (fisheries, vessel traffic, climate) on threatened species like gray whales, manta rays, and pelagic sharks.

Leads the Ocean Ecology Lab team developing conservation technologies including drone surveys, animal-borne cameras, and stable isotope analysis. Collaborates with fisheries managers and international conservation organizations.
