SPDS ERP CVs - DEC 2017

ChromaDex Analytics , Boulder, Colorado 2004 to 2009 Developed analytical methods to assess the safety and quality of botanical dietary supplements while leading analytical support for the isolation division. Samples ranged from raw plant material, to extracts, to finished products. Coordinated R&D projects in isolation services. • Serve as a reviewer for scientific journals (Planta Medica, JAOAC, Journal of Separation Science, Journal of Chromatography, Chromatographia). National Center for Natural Products Research , University, Mississippi 2001 to 2003 Developed analytical methods to assess the safety and quality of botanical dietary supplements. Areas of focus were Ephedra (species fingerprinting and ephedrine alkaloid analysis), Aristolochia and Asarum (species and population studies of aristolochic acid content), St. John’s Wort (SLV for AOAC official methods), Senecio and Symphytum (pyrrolizidine alkaloid analysis with ELSD), Viagra (independent analysis of herbal products illegally adulterated), Coleus forskohlii (quality analysis of market products), Ginkgo (batch to batch consistency studies), Centella asiatica (quality analysis of market products), lemon grass (method developed for analysis of volatiles), Echinacea (plant propagation analysis), Goldenseal (plant propagation analysis), purity studies of isolated compounds for standardization purposes and analysis of catfish pond water for the USDA. • Prepared summary reports for funding agencies, proofed manuscripts and grants, aided in grant writing. Served as a reviewer for scientific journals (Planta Medica, JAOAC, and J of Chrom B). Virginia Commonwealth University , Richmond, Virginia 1995-2000 Graduate Research Assistant Developed synthetic methods including the modification of the diene moiety of maytansine and its homologues to improve their water solubility and decrease their toxicity for better drug delivery as well as the structural activity requirement of the diene moiety. Research also involved the isolation and elucidation of bioactive dihydroagarofuran sesquiterpene alkaloids from Maytenus putterlickoides by chromatographic and spectroscopic techniques. This research relied heavily on NMR. • Published two journal articles and thirteen presentations of research results at international, national, regional, and local meetings. • Advised undergraduates doing independent studies in the laboratory. 1995-1998 Nuclear Magnetic Resonance Spectrometer Technician – Main troubleshooter and technician for departmental 300 MHz GE Nuclear Magnetic Resonance Spectrometer. Teaching Assistant - Instructor of Qualitative Organic Chemistry and Organic Chemistry Labs, and instructor of General Chemistry Recitation. Responsible for lectures, quizzes, and final grades for the students. Served as a substitute lecturer for General Chemistry. Summer 1994 Research Assistant Intern - Isolation and structural elucidation of natural products (acetogenins) by chromatographic and spectroscopic techniques. • Resulted in the publication of one journal article. 1995-1998
