Biostatistics

Since 1997, I have been principally employed developing statistical methods for defining and distinguishing groups of biological test samples based on biochemical analysis. The problem has always been to answer the question "how are these samples different from those?" In my specific sub-field, the answers come in the form of biomarkers. To elucidate a biomarker, I've developed custom implementations of unsupervised hierarchical cluster analysis, principle component analysis, ANOVA, ANCOVA, linear discriminant analysis, SIMCA, and other techniques of used widely in biostatistics, chemometrics, and general data science. I use both frequentist and Bayesian methods.
