EducationB.S. Chemistry, University of New Hampshire, Durham, NH, May 1982 Ph.D. Chemistry, Indiana University, Bloomington, IN, September 1989 Major: Analytical Chemistry Minor: Physical Chemistry Bachelors ThesisThe Statistical Analysis and Use of Analytical Calibration Curves A comprehensive statistical background to the calibration problem is presented, emphasizing the practical use of statistics to extract useful chemical information from experimental data. Doctoral ThesisAnalytical Applications of Supersonic Jet Spectroscopy and the Application of Correlation Analysis Techniques in Mass Spectrometry Experiments focused upon efforts made to improve the selectivity of both fluorescence and ionization detection (using a time-of-flight mass spectrometer) through the use of supersonic beam sampling techniques. A dramatic increase in mass resolution due to the geometric cooling effect was demonstrated. The excited state spectroscopy and dynamics of internally cold sample molecules and weakly bound van der Waals clusters produced in expansions of both rare gases and supercritical fluids was studied. In order to perform these experiments a supercritical fluid chromatograph time-of-flight mass spectrometer system utilizing a supersonic jet interface was designed and constructed. Simplex optimization techniques were applied for the improvement of instrument resolution. The application of correlation analysis techniques (from information theory) was examined as both a means of increasing the trace analysis sensitivity of the mass spectrometer and as an alternative tool in the automated identification of compounds from their mass spectra.

Research & Teaching SeminarsThe following is a list of seminars that describe the work being done in my research group or in my classes. The presentations can be geared to different levels (general public, undergraduate, graduate, etc.) depending on the make-up of the audience. As our research work covers both biological and synthetic polymer systems, in many cases the examples covered can be customized to the audience as well. Please call or e-mail to set up a mutually agreeable day and time. Research Seminars"Quantitative Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry: Fact or Fantasy?" (or "The 'Black-Art' of MALDI Sample Preparation") "New Adventures in the MALDI TOFMS Analysis of Biological and Synthetic Polymers" (the emphasis of the seminar can be shifted between biological or synthetic polymer systems) "Quantitation of Polymers using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry" "Informatics and Mass Spectrometry: Applying Correlation Analysis Techniques to Extract New Information from Mass Spectral Data" "The Importance of Sample Preparation for Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry" Teaching Seminars"Analytical Calibration: What is the Best-Fit Line Through the Data (and What Do I Do Once I Have It)?"
