One of my strongest interests is the use of statistical tools to facilitate the conservation and reclamation of native plant communities. My research in this area has resulted in new approaches for both finding the correct number of plant communities in a landscape, and modeling optimal environments of native plant communities to aid in reclamation.
I am currently the principal investigator of a study to determine the effect of exotic mountain goats on native alpine vegetation in Yellowstone National Park. This study, essentially an extension of my doctoral work, will continue through 2011. A video describing this work can be found here.
I have created an R package asbio (applied statistics for biologists) which contains hundered of functions for statistical pedagogy and biological research. Asbio serves as a software companion to a biostatistical textbook I am completing : "Statistical Foundations for Biologists, a Textbook Using R (under contract; CRC Press; release date SP 2012)".
