I received my Ph.D. from the University of Wisconsin-Madison and began a postdoctoral fellowship in 1983 at the Marine Biological Laboratory’s (MBL) Ecosystems Center in Woods Hole, MA. In 1996-97, I was awarded a Fulbright Research Fellowship to work at the Norwegian Institute of Water Research (Oslo). After moving through the ranks to Senior Research Scientist, I the MBL left in 2002 to serve as co-Director of the National Science Foundation's (NSF) Ecosystem Studies Program. In 2003, I joined the University of Michigan as Director of the Biological Station and Professor in EEB.
I am interested in ecological and biogeochemical processes that determine ecosystem dynamics and functioning at local, regional and global levels. I conduct field studies in temperate forests and arctic tundra to improve understanding of how ecosystems respond to climate change, air pollution and physical disturbance. I am particularly interested in how interactions among soil biota, plants and climate interact to determine ecosystem structure and stability.
