Dr. Susy ZieglerDr. Chris Crawford (Ph.D. , 2013)
Dr. Susy Ziegler was the first tree-ring scientist hired on faculty at the University of Minnesota and founded the research group that would later become the Center for Dendrochronology. We owe Susy an enormous debt for her work putting UMN on the map in dendrochronology and dendroecology. In 2010, she left Minnesota to join the faculty of Northern Michigan University, where she is continuing her work studying the northern forests of eastern North America.
Assessing historical trends in snowpack variability across the Northern Rocky Mountains using remote sensing and dendrochronology approaches
Chris's dissertation focused on remote sensing of snowpack in the interior of western North America, dendroclimatology of the Northern Rockies and Southern Appalachian Mountains, and low-frequency climate variability. He is a post-doctoral fellow at NASA's Goddard Space Science Center, working in the Cryospheric Sciences Laboratory.

Tree ring reconstruction of island and mainland fire events along a historic canoe travel corridor in Minnesota's Boundary Waters Wilderness
Lane is a native Minnesotan who conducted fire history research in the near-boreal forests of the Boundary Waters Canoe Area Wilderness.
Erika Wertz (B.Sc., 2012)
Testing whether vessel characteristics in bur oak can serve as proxies for severe Red River floods within the United States
Erika is employed by the Colorado State Forest Service in Canyon City, Colorado.
Danny Margoles (M.A., 2010)
Mountain pine beetle - whitebark pine dynamics in a subalpine ecosystem of the Pioneer Mountains, southwest Montana
As part of his thesis research, Danny focused on a historic outbreak of mountain pine beetle in the high-elevation whitebark pine forests of Montana.
Dr. Grant Elliot (Ph.D., 2009)
Multi-scale influences of climate on upper treeline dynamics along a latitudinal gradient in the Rocky Mountains, USA
Grant's dissertation dealt with the impacts of climatic variability and disturbance regimes on vegetation patterns in Rocky Mountain and Minnesota forests. He is an Assistant Professor in Geography at the University of Missouri.
Dr. Evan Larson (Ph.D., 2009)
Status and dynamics of Whitebark pine (Pinus albicaulis Engelm.) forests in southwest Montana, central Idaho, and Oregon, U.S.A.
Evan's dissertation research examined the variability of fire regimes and stand dynamics in whitebark pine forests across the central distribution of the species, and its causes. Evan is an Assistant Professor of Geography and Geology at the University of Wisconsin-Platteville.
Sarah Margoles (M.A., 2009)
Perspectives on oak savanna restoration in Minnesota: a dendroecological approach
Sarah's thesis work used fire scars to reconstruct fire history in oak savannas in central and southern Minnesota.
Dr. Julia Rauchfuss (Ph.D., 2009)
Dynamics of old-growth forests of Minnesota
Julia studied the dynamics of old growth forests in the 'Lost 40' in northern Minnesota, Itasca State Park, and the Big Woods in south-central Minnesota. Julia is currently a post-doctoral researcher at Mid Sweden University.
