Research Interests
My research interests include more traditional biometry topics, such as volume, taper, and weight equations derived for various species and regions; statistical sampling and inventory issues; and the impacts of various silvicultural treatments on stand development. Further, I have more wide ranging research interests, e.g., quantitative issues relating to the growth and yield of forest stands with an emphasis on the spatial relationships between individual trees in a stand; using Bayesian statistical methods to look at spatial matrix correlation structures (with respect to a forest stand); evaluating the differences between different levels of genetic homogeneity at the individual tree and stand-level; and modeling diameter distributions for a range forest stand conditions. I try to be very flexible on the research theses my graduate students work on and I strive to make sure that their research thesis helps to achieve their professional goals.
