John P. Tyminski

Title: Affiliate Researcher

John joined the Center for Shark Research as a Staff Biologist in 1995 and was promoted to Senior Biologist in 2002. John has worked on a diverse range of projects involving a broad array of shark and ray species, including field and analytical work that has focused on shark nursery areas, relative abundance, sexual dimorphism, movement and migration and the characterization of the artisanal elasmobranch fishery in the Gulf of California. Most recently, John has been active in studying the behavioral ecology of whale sharks off Mexico's Yucatan Peninsula. In the lab, John continues to extend the work from his graduate studies that examined the role of steroid receptors in the reproductive tissues of male bonnethead sharks.
