Career Summary:

Since 1972, I have worked as a Plant Physiologist at the USDA Forest Service Northeastern Research Station and have been located at the Forestry Sciences Laboratory in Warren, PA, since 1973.

During my career, I have worked extensively on problems of forest regeneration, including plant-plant and herbivore-plant interference relationships, and methods of vegetation management. Recently I have been a member of a collaborative team that studies the factors contributing to sugar maple decline in Pennsylvania.

I serve as an Associate Editor of the Canadian Journal of Forest Research and previously was an Associate Editor of Forest Science. I have also served as national chairman of the Society of American Foresters Physiology Working Group and chairman of Division 2.08 of the International Union of Forestry Research Organizations. I currently hold Adjunct Professor positions at the School of Forest Resources at the Pennsylvania State University and at the State University of New York, College of Environmental Science and Forestry.
