  • Research Associate
  • Forest Community and Disturbance Ecology
I am usually out of the office, but when on campus I'm at:
316 Forest Resources Building

University Park, PA 16802

Education

  • Ph.D. 2007 Forest and Disturbance Ecology, University of Minnesota
  • M.S. 1996 Nonvascular Community Ecology, Oregon State University
  • B.S. 1992 Environmental Economics, Linfield College

My background is in plant community ecology in forested ecosystems and in the multivariate analyses used on such data, but I'm a synergistic thinker interested in the application of logic to study design and communication.  At the moment, I provide trainings to ecologists in the art of multivariate community data analysis and collaborate with the Silviculture & Applied Forest Ecology Lab here at Penn State.

Interests

I teach short-courses on the appropriate use of multivariate data analysis in community ecology, specifically using the PC-ORD software.  These trainings are intended to introduce multivariate statistical concepts,  describe the classification, ordination, and other available tools, and train users in a defensible data analysis approach and process.  The 2016 second edition of my book Multivariate Analysis for Ecologists:  Step-by-Step is meant to supplement these trainings or serve as a stand-alone tool for self-guidance.

I also collaborate with the Silviculture & Applied Forest Ecology Lab here at Penn State and consult on data analysis and scientific manuscript preparation and editing.

Between 1990 and 2010, I was immersed in field research on all aspects of commercial moss harvest.  This included assessing species composition, biomass distribution, cover and biomass growth rates, post-harvest recovery dynamics, and alternative management approaches, mostly in western Oregon.  Oregon State University now maintains the website on this topic.
