Ralph Turingan, Ph.D.

Professor | Ocean Engineering and Marine Sciences | Florida Tech


Dr. Turingan's research is on the ecology and evolution of organismal design in vertebrates.

Areas of Expertise (5)


Fish Biology


Physiological Ecology

Marine Biology


Dr. Ralph Turingan earned a bachelor’s degree from the University of the Philippines, a master’s degree from the University of Rhode Island and a doctoral degree from the University of Puerto Rico. He had post-doctoral training at Florida State University. He has been on the Florida Tech faculty since 1995.

His research on the ecology and evolution of organismal design in vertebrates uses the fish-feeding system as a model with the goal of elucidating the roles of ecological and evolutionary processes in explaining organismal diversity.

Dr. Turingan is a two-time recipient of the prestigious Fulbright Scholar award. Under his first Fulbright grant, he led a marine fish biology course in the Philippines at the University of the Philippines in Visayas, Iloilo City. His second Fulbright award was in recognition of his continuing collaboration with international scientists working in the Philippines.

He has conducted ecophysiological research on coral-reef fishes in the lesser known but critical waters between the Philippines and Taiwan.

Dr. Turingan is also director of the Aquaculture Laboratories at Florida Tech.

No fish story! Research finds marine reserves sustain broader fishing efforts

ScienceDaily  radio


In their examination of marine reserves, also known as marine protected areas or MPAs, around coral reefs in the Philippines, Robert Fidler, a Fulbright scholar who recently received his Ph.D. from Florida Institute of Technology, and his major professor, Fulbright faculty scholar Ralph Turingan, found evidence that MPAs in fact helped to produce and maintain the more desirable large-bodied and older fish within populations that have been fished by local fishermen for centuries.
