About the Presenter and the Panelists

Tim Palmer is the author of 20 books about rivers, conservation, and the environment, including Rivers of America and Trees and Forests of America. His books, articles, slide shows to public audiences, and lectures to college classes have reached tens of thousands of people over the past 30 years with an inspiring message about being engaged in the future and fate of natural places.

As journalist Ted Williams wrote, “Tim’s tireless, eloquent advocacy for rivers and forests has made a huge difference….I have long depended on Tim for information and inspiration.” And Rebecca Wodder of American Rivers said, “Tim is among the most gifted communicators I have had the pleasure of knowing.”

Tim’s willingness and ability to go beyond what’s expected is evident to anyone who meets or works with him. His books, photos, and motivating talks all show his ability to reach out to diverse audiences, to present complex issues accurately and understandably, and most of all, to motivate people to care about the earth. 

Tim has been involved in river conservation since 1970 and has received the Lifetime Achievement Award from American Rivers, the River Conservationist of the Year Award, and other honors. Paddler magazine named him one of the “10 greatest river conservationists of our time” and one of the “100 great paddlers of the past century.

For his writing he has received the National Outdoor Book Award, the Independent Publishers Book Award, and the Director’s Award for the best book about a national park.

Tim speaks frequently to audiences and college classes nationwide and lives in Port Orford, Oregon.

Christopher J. Duffy is a Professor in the Civil and Environmental Engineering Department at Penn State. He has held visiting appointments with Los Alamos National Lab, Cornell University, and Ecole Polytechnic Lausanne. He was a Senior Fellow at the Smithsonian Environmental Research Center in 2007.

Duffy's research has dealt with the application of time series analysis and modeling applied to the hydrology and hydrochemistry of groundwater and surface water systems, natural geochemical tracers, environmental isotopes, and existing contamination histories to study the response of hydrologic systems to stochastic variability in climate/weather forcing.  These studies have taken place in the Alps, Rhine River, Rio Grande River, Idaho National Engineering Laboratory, Los Alamos National Laboratory, Colorado River, Utah/Nevada, and, of course, Pennsylvania.

Since 2004, Duffy and his team have focused on developing the spatially-distributed, physics-based modeling code PIHM (Penn State Integrated Hydrologic Model) for multi-scale, multi-process applications. This research was funded by NSF, EPA and NOAA. The model itself is "tightly-coupled" with PIHMgis, an open-source GIS. Current work involves the addition of parameter estimation tools, a new direct method for simulating the “age” and residence time in watersheds. Duffy is the PI on the NSF funded Critical Zone Observatory at Shale Hills.

Heejun Chang is a Professor of Geography at Portland State University. His teaching and research focus on water sustainability in a changing environment using geospatial analysis. Specifically, he recently investigated the impacts of climate variability and change on water resources, land cover change and water quality, urban flooding and infrastructure management, and combined effects of climate change and urban development on ecosystem services shift. Chang has served as the lead author of the freshwater section of the First Oregon Climate Change Assessment Report and a representative for the Willamette River Basin in UNESCO’s HELP (Hydrology, Environment, Land and Policy) program. He obtained his Ph.D. at Penn State with Dr. C. Gregory Knight as his major advisor.

Lisa Wainger is a Research Associate Professor of Environmental and Spatial Economics at the University of Maryland Center for Environmental Science. Her primary research interest is developing integrated ecological and economic analysis tools to communicate changes in ecological conditions in terms of socio-economic impacts. Her work emphasizes the spatial variability of ecosystem service benefits and applies that understanding to create decision support tools for prioritizing restoration and preservation.These tools, which analyze risk and economic efficiency, have been applied nationally and internationally to issues of agro-ecosystem management, invasive species, wetland mitigation, preserving habitat for rare species, and water quality. Wainger currently serves as a special economics advisor to the US EPA Ecosystem Services Research Program and serves on the Executive Committee of the Scientific and Technical Advisory Committee to the Chesapeake Bay Program.

Andy Warner has more than twenty years of experience on environmental and conservation projects and policy relating to water, water quality, and floodplain management, including twelve years with The Nature Conservancy

Warner has held an affiliate faculty position at The Pennsylvania State University since 2000.
working on rivers in the United States, Asia, Latin America, and Africa. Warner is currently a Senior Advisor for Water Management with the Conservancy's North America and Global Freshwater Programs, where he works with government agencies and other managers to implement innovative water management strategies that meet human demands while maintaining healthy ecosystems. One of Warner’s roles is as the Conservancy’s National Coordinator of the Sustainable Rivers Project, a river restoration program run jointly with the U.S. Army Corps of Engineers. Sustainable Rivers focuses on defining and implementing environmental flows through adaptive reservoir management, and currently involves thirty-six Corps dams in eight river basins across the United States. The program also involves joint Corps-Conservancy training and software development, staff exchanges, and publications.
