Awards & Honors

In 2004, Mark was honored by ISI Citation Index as the most cited scientific author in the Northern and Western Hemispheres regarding coral reef ecology during the past decade. A Fulbright Senior Scholar and Aldo Leopold Leadership Program Fellow, Mark was honored in 2016 as a Fellow of the International Coral Reef Society, and in 2023 received the Lifetime Achievement Award from the Western Society of Naturalists (the oldest biological society in the western USA).

Service

Mark has served on the editorial boards of 5 scientific journals — Coastal Management, Coral Reefs, Ecology, Ecological Monographs, and PeerJ — as well as an ad hoc editor for the Proceedings of the National Academy of Sciences.  He was an executive appointee of both the Clinton and Bush administrations to the Marine Protected Areas Federal Advisory Committee, which he chaired for 3 years.  He has also served on the National Science Foundation Geosciences Advisory Committee as chair of the ocean science subcommittee, and presently serves on the Papahānaumokuākea Marine National Monument advisory council.  In 2016, Mark co-organized a joint exhibit by artists and scientists “Art-Sci: Where Art and Science Meet,” now on permanent display in the Pacific Ocean Science and Technology building at UH Mānoa. Regularly involved in scientific outreach, Mark has on-line TEDx talks and has appeared on the PBS TV show Saving the Ocean.

Research History

Having studied kelp forest ecology in California as a graduate student, Mark originally began his research on the ecology of coral reefs as a National Science Foundation Postdoctoral Fellow at the University of Hawai`i from 1979 to 1981.  After another postdoc at U.C. Irvine (including studies of hummingbird ecology), he was a professor of marine ecology and conservation biology at Oregon State University from 1984 through 2012.  Mark’s research spans the behavioral, population, and community ecology of coastal marine fishes, increasingly in the context of conservation biology, and occasionally fisheries ecology.  More recently, he has focused on helping to conserve and restore the coral reefs themselves. His projects emphasize undersea research, especially involving controlled field experiments.  Mark has published numerous peer-reviewed research papers on field projects in California, Oregon, Hawai`i, the U.S. Virgin Islands, the Bahamas, the Great Barrier Reef, and French Polynesia, including top ranked journals such as Science and the Proceedings of the National Academy of Sciences.  His research has helped to clarify mechanisms that naturally regulate populations and sustain biodiversity in the sea, topics of vital importance to managing fisheries and conserving species. 

Research Projects at UH

Mark started his position as the Sidney and Erica Hsiao Endowed Chair in Marine Biology in January 2013.  His first project in that position, collaborating with a group of UH colleagues, focused on tracing the life cycle of reef fishes from spawning to larval dispersal to life on the reef to capture by fisheries to distribution and consumption on land (the Fish Flow Project). His second project, conducted with his graduate students, explored the interactions among physical shelter for fishes and large invertebrates, the local abundance of these animals, and the recruitment, survival, and growth of corals (the Coral Resilience Module Experiment or CReME).  His current project, in collaboration with marine engineers, focuses on constructing permanent coral nurseries off Waikiki Beach that will serve as sites for caching and growing coral colonies until they are transplanted to the broader region to restore the coral reef (the REEFrame Project). These 3D-printed concrete structures will eventually become coral reefs in their own right.
