Member Biographies


Robert M. Hughes, Ph.D., Senior Research Scientist, Aminis Opes Institute (Bend, Oregon) and Courtesy Associative Professior, Department of Fisheries and Wildlife, Oregon State University, Corvallis joined the IMST in February 2004. Dr. Hughes received a B.A. in Psychology/Biology and an M.S. in Resource Planning and Conservation from the University of Michigan. In 1979, he received his Ph.D. in Fisheries and Wildlife from Oregon State University. Dr Hughes has over 25 years of experience in sampling and analyzing data for fish assemblages in various parts of the US, including previously serving as the indicator coordinator for the Environmental Monitoring and Assessment Program (EMAP) - - Surface Waters. He developed monitoring techniques and indicators for bird, fish, macrobenthos, and algae assemblages in northeastern US lakes, Appalachian streams and rivers, and western US streams and rivers. He has also developed fish assemblage indicators for Indian, French, and Brazilian rivers. Dr. Hughes has published 104 peer-reviewed manuscripts, co-edited three books, served as associate editor for two professional journals, and given over 100 invited presentations. He was president of the Western Division of the American Fisheries Society (AFS) in 2006-2007, the AFS Water Quality Section in 1999-2001, and the AFS Oregon Chapter in 1994-1995. Recent professional awards include the 2007 Best Paper Award in Transactions of the American Fisheries Society, a 2007 Fulbright Senior Scholar Award to Brazil, and the 2006 Environmental Stewardship Award by the North American Benthological Society. Dr. Hughes' initial appointment ended June 30, 2008 and he is now serving his second term.

Nancy Molina, M.S. has worked at the interface of science and natural resource management since 1972. After completing an undergraduate degree in Geography at Portland State University in the early 1970's, she joined one of the USDA Forest Service's first multidiscipline land use planning teams, located on the Mt. Hood National Forest. Subsequently Ms. Molina earned a graduate degree in Botany/Ecology from Washington State University, then returned to the Forest Service where she spent 20 years working as a field ecologist in NW Oregon/SW Washington. During that time she conducted ecological studies for four National Forests, and authored and co-authored a variety of ecological guides and other publications, including "Forest Landscape Analysis and Design", a widely-used guide to landscape-scale ecological planning. She has presented numerous talks and workshops on topics related to ecosystem management and landscape ecology, and has assisted with landscape planning projects in Taiwan, Great Britain, and Canada.

Beginning in 1998, Ms. Molina managed a research program for the PNW Research Station that provided science support to public agencies within the Northwest Forest Plan area. In 2002 she became Chief of the Physical Sciences Branch of the USDI Oregon/Washington Bureau of Land Management, and in 2005 accepted a special assignment to coordinate the initial efforts of the NWFP agencies to respond to the 10-Year Monitoring Reports and Science Synthesis. Ms. Molina retired from federal service in 2005, and currently co-chairs the IMST.

Carl Schreck, Ph.D., Leader, Oregon Cooperative Fish and Wildlife Research Unit, Biological Resources Division, U.S. Geological Survey, Corvallis, Oregon. Dr. Schreck has been researching the biology of fishes for nearly 30 years. He has an A.B. in Zoology from the University of California, Berkeley, a M.S. in Fisheries Science and a Ph.D. in Physiology and Biophysics and Fisheries Science from Colorado State University. He currently serves as Leader of the Oregon Cooperative Fish and Wildlife Research Unit and is senior scientist in the Biological Resources Division, U.S. Geological Survey and as a Professor in the Department of Fisheries and Wildlife at OSU. His research has focused primarily on salmonids. He applies environmental physiology to address environmentally relevant questions; this research has lead to over 200 published papers. Dr. Schreck is a member of several scientific and management teams, organizations and committees. He is currently serving a four-year term as President of the International Federation of Fish Endocrinologists. He has won numerous national teaching, research, and publication awards.

J. Alan Yeakley, Ph.D. is Professor of Environmental Science at Portland State University, Portland, Oregon. He joined the IMST in February 2009. He holds a Bachelors degree in mathematics from Texas A&M-Commerce and a Masters in environmental science from the University of Texas, Dallas. He received his Ph.D. in environmental science in 1993 from the Unirversity of Virginia, and held a post-doctoral appointment with the School of Ecology at the University of Georgia before joining the Portland State faculty in 1994. Dr. Yeakley is certified as a professional hydrologist (P.H.) in the area of water quality by the American Institute of Hydrology. He has served on numerous scientific advisory committees and review panels, is an associate editor with the international journal Écoscience, and is a founding member of the Urban Ecosystem Research Consortium (UERC) of Portland/Vancouver. In addition to watershed hydrology, Dr. Yeakley and his graduate students conduct research in the areas of forest ecology, riparian ecology, urban ecology and urban environmental management.
