Cooperative Forest Ecosystem Research
CFER Staff Biographies

The Cooperative Forest Ecosystem Research (CFER) staff consists of principal investigators, research assistants, information exchange personnel and graduate students.


Principal Investigators (P.I.s)


David E. Hibbs

David Hibbs
David Hibbs is program coordinator and a forest ecologist for the CFER program. He is a professor in the Department of Forest Science at Oregon State University where he teaches forest community ecology and directs the Hardwood Silviculture Cooperative. He has his BS in Plant Ecology from Carleton College, his MS in Forestry from the University of Massachusetts, and his Ph.D. in Forest Ecology from the University of Massachusetts. His research interests broadly include stand development and succession in temperate and tropical forest. Much of his current research is focused on disturbance, development, and pattern in riparian forests


Jason Dunham

W. Daniel Edge
Jason Dunham joined the CFER Research team in June of 2005 as an aquatic ecologist with the USGS Forest and Rangeland Ecosystem Science Center. Jason's research has focused on the ecology and conservation biology of native fishes and their habitats. His most recent work has addressed the influence of natural disturbance on fish populations and habitats in streams, population monitoring for stream fishes, modeling fish-habitat relationships, and nonnative fish invasions. Jason has degrees in Zoology from Oregon State University (B.S., 1987) and Arizona State University (M.S., 1995), and a degree in Ecology, Evolution, and Conservation Biology from the University of Nevada-Reno (Ph.D., 1996). He also holds a courtesy appointment in the Department of Fisheries and Wildlife at Oregon State University and adjunct affiliations with the Departments of Biology at Boise State University and University of Nevada-Reno.


W. Daniel Edge

Dan Edge
W. Daniel Edge is the Department Head in the Department of Fisheries and Wildlife at Oregon State University and one of the wildlife ecologists on the CFER science team. Dan received a BS in Wildlife Biology, a BS in Forestry, a M.S. in Wildlife Biology, and a Ph.D. in Forestry, all from the University of Montana. Dan's primary research interests are the impacts of forestry and agricultural practices on watchable wildlife communities. Dan is the Northwest Section Representative of The Wildlife Society and a Certified Wildlife Biologist.


Robert E. Gresswell

Robert E. Gresswell
Robert E. Gresswell received degrees from the University of New Mexico (BS), Utah State University (MS), and Oregon State University (Ph.D.). Since 1997, Bob has been working as an aquatic ecologist for the USGS Forest and Rangeland Ecosystem Science Center and the CFER Program. In 2004, he accepted a position with the USGS Northern Rocky Mountain Science Center in Bozeman, Montana, but will continue to play an important leadership role with CFER, especially in the areas of aquatic ecology and fish biology.


Judith Li

Judy Li
Judith Li is an Assistant Professor in the Department of Fisheries and Wildlife (OSU) where she has been a member of the faculty for 11 years. She is a stream ecologist with particular interest in freshwater invertebrates and food webs. Her studies have ranged from forested systems of the Oregon coast and the Cascades, to arid eastern Oregon. Her research is most often multidisciplinary in which she, her students, and colleagues have examined stream invertebrate distributions to understand responses to physical and chemical gradients, to fish and avian predation, and as tools in bioassessment. Her current research focuses on riparian/stream interactions among vertebrates and invertebrates in mesic, arid, and urban settings.

Klaus Puettmann

Klaus Peuttmann
Klaus Puettmann is an associate professor in the Department of Forest Science at Oregon State University. Klaus received his diploma from Albert-Ludwig University, Freiburg, Germany and his Ph.D. from Oregon State University. His research interests include silviculture of temperate forests, regeneration dynamics in diverse structured forests, plant interaction, and density management. He recently joined the CFER research team as the lead investigator of BLM’s Density Management Study.


Steven Perakis

Steve Perakis
Steven Perakis is a research ecologist with the USGS Forest and Rangeland Ecosystem Science Center. Steve's research centers on understanding biogeochemical cycles in terrestrial ecosystems, and he has particular interest in discerning how processes and activities within forests shape nutrient losses, whole-system nutrient balances, and linkages between terrestrial and aquatic ecosystems. He has worked extensively in temperate forests of Chile and Argentina, and more recently in blue oak savannah-grassland of Sequoia-King's Canyon National Park. Steve has degrees in Ecology and Ecosystem Science from the University of Pennsylvania (BS, 1990), the University of Washington (MS, 1994) and Cornell University (Ph.D., 2000), with a year of post-doctoral experience from Stanford University. He also holds a courtesy appointment in the Department of Forest Science at Oregon State University.


Christian Torgersen

Christian Torgersen
Christian Torgersen is a research landscape ecologist with the USGS Forest and Rangeland Ecosystem Science Center and a fish ecologist with the CFER program. He works in Seattle, Washington at the FRESC Cascadia Field Station at the University of Washington and colloborates with CFER scientists in landscape modeling and stream fish ecology projects. A graduate of Oregon State University (Ph.D., 2002), Christian has an interdisciplinary background in fisheries science and geography and is interested in the influences of landscape pattern and habitat fragmentation on the distribution of stream fishes. His research involves the use of geospatial applications, such as remote sensing and GIS, and statistical modeling to predict the occurrence and abundance of coastal cutthroat trout in western Oregon.
 
 


Research Assistants


Doug Bateman

Doug Bateman
Doug Bateman is a research assistant for the CFER program. He has worked for the College of Forestry at Oregon State University since 1989. Doug received his MS in Fisheries Science from Oregon State University in 1998. He is interested in disturbance ecology and the natural history of aquatic organisms.


David Hockman-Wert

Tom Manning
David Hockman-Wert is a research technician for the CFER program studying landscape pattern and fish distribution using geospatial techniques. He received his B.A. in Biology from Eastern Mennonite University and his M.A. in Environmental Studies from the University of Oregon. His multi-disciplinary interests include GIS, landscape ecology, cultural geography, and the human dimensions of natural resources.


Tom Manning

Tom Manning
Tom Manning is a research assistant currently working with CFER on the Timbered Rock project, investigating the effects of salvage logging on wildlife populations. He received his MS in Environmental Biology from the University of Minnesota, Duluth in 1989 and has worked in OSU's Department of Forest Science since 1995. His work since then has centered on effects of forest management practices on small mammal populations.

 
 

Information Exchange


Irene Schoppy

Nancy Creel
Irene Schoppy is the administrative assistant for the CFER program. She provides financial, administrative, and clerical support for researchers and outreach specialists participating in the CFER program. Irene manages mailing lists and the CFER website, prepares the CFER research proposals and annual reports, and provides monthly financial statements. She works closely with all members of the program's staff, in support of the research and information exchange goals of the CFER program.


 
 

Graduate Students

Michelle Donaghy Cannon is a Ph.D. student in the Department of Forest Science and the Department of Fisheries and Wildlife. She is studying how birds are distributed in large, severely burned patches relative to remnant, unburned forest.

Joselin Matkins is a Master's student in the Department of Forest Science. She is investigating how nitrogen and other factors influence the decay of Douglas-fir and red alder leaf litter in both terrestrial and aquatic habitats of riparian zones.

Bill Rehe is a Master's student from the Department of Fisheries and Wildlife. He is examining the influences of landscape variables on age and growth of coastal cutthroat trout

Aaron Thiel is a Master's student in the Department of Forest Science. He is conducting research on the patterns of nitrogen dynamics across gaps in thinned forests of western Oregon.
