Awards & Honors

In 2004, Mark was honored by ISI Citation Index as the most cited American scientific author on coral reefs in the past decade.  A Fulbright Senior Scholar and Aldo Leopold Leadership Program Fellow, he serves as a subject-matter editor for the scientific journals Ecology and Ecological Monographs, as a member of the editorial board of Coastal Management, and as an ad hoc editor for the Proceedings of the National Academy of Sciences.  Mark 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 also served on the National Science Foundation Geosciences Advisory Committee as chair of the ocean science subcommittee.  Regularly involved in scientific outreach, Mark has on-line TEDx talks on coral reef conservation and the lionfish invasion.

Research Interests

Mark started his position as the Sidney and Erica Hsiao Endowed Chair in Marine Biology in January 2013.  He 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, 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.  His projects emphasize undersea research, especially involving controlled field experiments.  Mark has published over 100 peer-reviewed papers on field projects in California, Oregon, Hawai`i, the U.S. Virgin Islands, the Bahamas, the Great Barrier Reef, and French Polynesia.  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.  Projects in Hawai'i include linking local ecology to larval dispersal of reef fishes (marine metacommunity ecology), as well as documenting the interactions among structural shelter for fishes, reef fish abundances, and the structure of reef benthic communities (coral reef ecological resilience).
