Manager of the Gas Chromatography Skills Center, Union CarbidePerformed gas chromatography method development. Developed methods to measure trace level impurities (PPM and PPB) in polymers and monomers including the following:• Headspace SPME method to measure PPB levels of trimethylamine in ethoxylated methylglucoside• method to measure PPM levels of alkanolamines in polyethylene oxide• method to measure PPB level chlorinated impurities in EPDM• method to identify and quantify botanical oils added to polyethylene oxide• method to quantify cyclopentadiene in ethylidene norborneneNMR spectroscopy of polymers and catalysts using Varian 400 MHz NMRSolved problems using X-ray photoelectron spectroscopy including• the surface migration of additives in polymers• the surface contamination of polymers by stress cracking agents• the surface fluorination and oxidation of polyethylene• the adhesion and bonding of polymers• polyelectrolyte deposition• the characterization of polypropylene catalystsUsed atomic force microscopy to• characterize polymer blend morphology• characterize the surface structure of adsorbed polyelectrolytes

• Performed chromatographic software testing of HPLC software. Software was tested using a USP method that applied reverse phase HPLC for the analysis of steroids.• Performed HPLC system comparisons with competitor’s systems.

• Developed, built and tested pilot scale photocatalytic air cleaners for the gas phase photooxidation of formaldehyde and other VOC's. Developed and tested novel photocatalysts for VOC oxidation.• Performed analyses of low concentration (PPBV) VOC's to evaluate air cleaner performance by GC and GCMS methods.• Wrote reports to funding agencies including NIST and EPRI

• Explained and predicted photooxidation kinetics for a variety of chlorinated hydrocarbons.• Helped develop a hydrothermal treatment process for chloroacetic acids. Designed, built and tested a pilot scale high pressure hydrothermal reactor.• Wrote final report to EPA

Researched intramolecular hole transfer rates in organic radical ions using picosecond time resolved pulse radiolysis.
