He has years of hands-on, professional experience in project management, laboratory operations, quality assurance and experimental design for the characterization and quantitation of ionic and nonionic organic compounds in cGMP and Good Laboratory Practices (GLP) regulated environments.  Mr. Ogburn is an expert in analytical method development and validation in accordance with International Conference on Harmonization (ICH) and United States Pharmacopeia (USP) guidelines for HPLC-MS, HPLC-MS/MS, CAD, IC and other analytical techniques. He has performed and supervised these methodologies on a variety of projects, throughout all phases of the Investigational New Drug (IND), New Drug Application (NDA), and post-market evaluation phases (i.e. Phase 0 – Phase 4).  These studies included chemical and physical property determination, long and short term stability, kinetic solubility, pharmacokinetics and pharmacodynamics testing at advanced performance levels in the development and characterization of active pharmaceutical ingredients, drug products, drug delivery systems, process impurities and degradation products.
