Department of Forest Sciences
Faculty List
 John
Yarie
- Department Head - Professor of Silviculture; West Virginia University
'71, B.S.; University of Maine '74, M.S.; University of British Columbia
'78, Ph.D. Dr. Yarie's research background is in forest nutrient cycling
and plant-soil relationships. He is also interested in applying site
specific knowledge to landscape level problems through the use of modeling
and Geographic Information Systems. He teaches forest ecology, theorectical
ecology, and research methods. He is director of the Forest Soils Laboratory.

 John
Fox - Associate Professor of Land Resources; Trinity College
'68, B.S.; University of Washington '70, M.S., '76, Ph.D. Dr. Fox's
research interests include modeling hydrologic effects of land-use changes;
the intertie between microclimate, mesoclimate and global climate change;
the spatial dimension of the concepts of sustained-yield and sustainability;
He teaches courses in watershed management, forest management, resource
measurements & inventory, environmental ethics, simulation and modeling,
and biometeorology. E-Mail: ffjdf@uaf.edu
 Glen
Juday - Associate Professor of Forest Ecology; Purdue University
'72 B.S.; Oregon State University '76 Ph.D. Dr. Juday's research investigates
community ecology, especially old-growth forests, natural area protection
and management, and long-term environmental monitoring. He teaches classes
in conservation biology and natural areas protection. E-Mail: ffgpj@uaf.edu
 Jingjing Lang - Assistant Professor of Forest Management, Beijing University 2001, B. S.; University of Wisconsin-Madison 2005, Ph.D. Dr. Liang is the Principle Investigator of the Forest Growth and Yield Program at UAF. His research focuses on the spatial and temporal analysis of boreal forests and climate change. He studies forest dynamics, including forest growth and yield, and carbon sequestration, with empirical models. He also investigates the effects of various factors on boreal forests, including bio diversity, human activities, and various catastrophic events, such as wild land fires, insects and disease. Dr. Liang studies the trade-off between economic and ecological objectives, and seeks the best boreal forest management regimes. A change of structure and species composition in Alaska's boreal forests may result from the global climate change. He looks into this issue with tree and stand records collected from the permanent forest plots established throughout the Interior Alaska since 1994. Dr. Liang's teaching is focused on natural resources management methods. Email: j.liang@uaf.edu
 Scott
Rupp - Assistant Professor of Forest Measurements; Pennsylvania
State University '93, B.S.; University of Alaska Fairbanks, '98, Ph.D.
My interests are in ecosystem and landscape ecology emphasizing secondary
succession, regeneration, and disturbance dynamics in subarctic and
boreal forests. Much of my enthusiam and exceitment for science is directed
toward the application of scientific knowledge to resource management
issues. My research is directed toward documenting productivity and
its controls at the level of individual trees and forest stands, and
studying the processes that make it possible to extrapolate these results
to the landscape level. I have applied computer simulation models to
address these issues for treeline ecosystems in northwestern Alaska.
I am currently applying similar modeling contructs to boreal forest
dynamics in interior Alaska as part of the Bonanza Creek Long Term Ecological
Research (LTER) Program. I teach our natural resource inventory and
measurements course and amworking to enhance field experiences for our
undergraduates. E-Mail: scott.rupp@uaf.edu
 David
Valentine - Assistant Professor of Forest Soils; Wittenberg
'81, B.A.; Duke University '84, M. S. and '90, Ph.D. Dr. Valentine's
broad research interest is in ecosystem ecology, biogeochemistry, and
element cycling in northern ecosystems. His past research focused on
the role of soils in forests, grasslands, and wetlands in generating
or consuming trace gasses, especially methane, that control Earth's
climate. His recent research has focused on the effects of wildfire
on soil respiration and carbon balance. He teaches courses in soils,
nutrient cycling, and integrating the major foundations of natural resource
management: natural sciences, economics, values/ethics, and policy.

 Dave
Verbyla - Associate Professor of Geographic Information
Systems (GIS) in Natural Resources; Rutgers University '79, B.S.; Michigan
State University '82, M.S.; Utah Sate University '88, Ph.D. Dr. Verbyla's
research interests include use of GIS technology for resource inventory
and climate change studies; integrating remote sensing and GIS for regional
analysis, and support for spatial analysis using GIS. He teaches courses
in geographic information systems, GIS analysis, and ARC Macro language
programming. E-Mail: ffdlv1@uaf.edu
 Trish
Wurtz - Affiliate Research Professor of Forest Sciences;
Brown University '82, B.S.; University of Oregon '88, Ph.D. Dr. Wurtz's
research interests include boreal forest plant population ecology, with
an emphasis on boreal management options. Other interests include ecology
and economics of non-timber forest products. E-Mail: fftlw@uaf.edu
