Cody Quinn Miller is a Marine Biologist and Conservationist specialising in the protection of vulnerable shark species and the preservation of global marine ecosystems. His career bridges field research, species policy, and scientific diving operations across more than 100 countries.
His professional background spans serving as a fisheries biologist for California State Fish and Wildlife, research at the Scripps Institution of Oceanography in Dr. Sandin's lab, and self-directed thesis fieldwork on the elusive Megamouth shark in Okinawa, Japan. His work is shaped by a personal ethos of rewilding and minimalism — intentionally stepping away from the digital world to invest directly in the natural environment.
He holds a Master of Resource Management in Coastal and Marine Management from the University Centre of the Westfjords / University of Akureyri in Iceland, and a Bachelor of Science in Marine Biology from the University of Hawaii at Manoa.
Cody's work is oriented around a single goal: advancing the science and policy frameworks needed to protect sharks and the ecosystems that depend on them. His field research and diving operations directly inform his approach to species protection at an international scale.
Cody's primary focus is developing and advancing policy frameworks that protect vulnerable shark species. Drawing on field data and international research experience, he works at the intersection of marine science and conservation law.
From the Scripps Institution of Oceanography to self-directed thesis fieldwork on the Megamouth shark in Okinawa, Cody collects primary data in conditions few researchers can access — bringing scientific rigour to some of the ocean's least-studied species.
Trained as a fisheries biologist with California State Fish & Wildlife and holding an MRM in Coastal and Marine Management, Cody approaches ecosystem health through both applied field science and evidence-based resource management.
A career built in the water, validated by the most rigorous diving and marine science programmes in the world.
Documented encounters across five species and four oceans — from the shallows of the Bahamas to the deep blue channel of the Maldives.
