Biography

Ron has conducted research in coastal and estuarine ecosystems since 1971. His research includes coastal ecosystem restoration; adaptive management of restored systems; benthic primary production; climate change and adaptation; carbon storage in restored coastal systems, and ecology of fisheries resources. Over his 45-year professional career, Ron has directed approximately 200 multidisciplinary ecological studies. He has worked on systems in California, Washington, Oregon, Alaska, Massachusetts, New York, Nebraska, and Alabama. He has published five book chapters, about 100 peer reviewed papers, hundreds of reports, made hundreds of professional presentations, and served on numerous professional committees. From 1985-1989 he chaired the Technical Advisory Committee of the EPA’s Puget Sound Estuary Program. Between 1991 and 2013, Ron managed the Coastal Ecosystem technical group at PNNL. During the mid-1990s to early 2000s, Ron (while working for PNNL) also taught courses in Coastal Zone Management, Wetland Restoration, and Oceanography at the four-year program in Environmental Studies at Western Washington University (Port Angeles campus). Because of the growing international reputation of his group, Ron was invited to South Korea in 2009 to present a keynote address on Coastal Ecosystem Restoration. He was invited to China in 2010 where he signed an agreement for joint cooperative research in coastal restoration between PNNL and East China Normal University, State Key Laboratory of Estuarine & Coastal Research in Shanghai, China. Since 2009, Ron has served on the Expert Regional Technical Group (ETRG) that evaluates restoration project proposals aimed as restoring ecosystem health and salmon in the Columbia River Estuary Ecosystem Restoration Program (CEERP) funded by Bonneville Power Administration and the Corps of Engineers. In 2011, Ron served as a member of US EPA Science Advisory Board panel reviewing the Great Lakes Restoration Program. In 2013, Ron served on a panel to advise the State of Louisiana on an adaptive management program for restoring their coastline. In 2015, the Governor of Washington appointed him to the Northwest Straits Commission. In 2014-16, Ron served on a National Research Council panel to develop recommendations for monitoring the effectiveness recovery actions in the Gulf of Mexico coastal ecosystem following the 2010 oil spill. Ron co-chaired the 2015 conference of the Coastal and Estuarine Research Federation (CERF), and co-chaired the 2016 Salish Sea Ecosystem Conference – a joint conference between the US and Canada. In 2014-2016, and again beginning in 2017, he has served part time as the Senior Science Advisor to the Puget Sound Partnership, which is the EPA National Estuary Program in Puget Sound. In 2010, Ron was elected to the Washington State Academy of Sciences based on career accomplishments. In 2011, he was elected to the Board of Directors, and in 2016 was elected president-elect of the Academy. Ron will serve as President in 2018-2020. The Academy advises the Governor on science, engineering and health issues affecting the State.

Ron retired from PNNL in June 2013, served in a part time retire-rehire capacity for three years, and was given Staff Scientist Emeritus status in June 2016.
