I teach and do research in analytical chemistry and in the application of statitics to chemical problems. Recent research has involved spectroscopy, liquid chromatography, and mass spectrometry for forensic fiber analysis and analytical toxicology, thermal reflectance imaging for biological stains at crime scenes, and noninvasive methods for detection of degraded audio tapes using mutlivariate statistical analysis for decision making on the basis of infrared spectroscopic patterns. These projects are guided by experimental design, optimization, and multivariate pattern recognition and machine learning approaches. I teach courses on statistics and experimental design for the American Chemical Society and do teaching in consulting work with industrial companies. ©
