Rochester, Minnesota


As a statistician engaged in clinical research programs, my interests reflect both medical and statistical areas. The former has been focused for the last several years on liver disease, liver transplant, hematology with particular emphasis on plasma cell malignancy, and physical medicine. Statistically, the major impetus of my work has been in survival analysis. Currently research includes: 1) correlated random effects models, applied to large family based genetics studies; 2) the analysis and understanding of microarray and proteomics data ; 3) expected survival computation and competing risks; and, 4) the application of tree based methods to survival data.
