Much of my work is consulting, where I give statistical advice (on design of studies and experiments, analysis and reporting). Favorite areas include wildlife biology, nutrition research, biochemistry, and fisheries. Most of my research is in spatial statistics, where geolocated data is used to create maps or test spatial models. I both write papers in this area and write software, in the form of R functions and packages. Recent work includes diffusion-based density and nonparametric regression estimators that work with maps that include boundaries and holes. I鈥檓 also working on software to implement nonparametric co-kriging (mapping multiple variables at the same time, using correlations between variables to improve the accuracy of the maps). I鈥檝e also done laboratory work on NMR of chemical mixtures and I鈥檓 working on models for identifying chemicals based on spectroscopy of mixtures of unknown chemicals. Finally, I鈥檓 also starting work on the causes of failure in sentinel node biopsy in melanoma, which will involve analysis of the SEER cancer data.
