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.
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 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.
