Lead technician in the quality control laboratory. Evans produces divalent sulfur chemistry used as precursor for many different applications. The lead chromatographer and in charge of methods development, overseeing the standard chromatography workflow and mentoring HPLC technican. Maintain and repair the QC laboratory's HPLC's, GC and ion chromatograph. Develop and utilize non routine spectrophotometric methodology. When needed perform routine testing in the Evans Chemetics wet lab.

PROFESSIONAL EXPERIENCE• Polymer characterizations – contributed to the mechanistic understanding of polymer degradation processes, hydrolysis of polyesters, the photo-degradation of polyethylene coated on paper, laser ablation of polymers, and long-term stability of polyurethanes and vinyl polymers in aqueous solution.• Preparative High Performance Liquid Chromatography – significant contributions to imaging chemistry teams in Optical Medical Imaging (OMI) Agents, Organic… Show more PROFESSIONAL EXPERIENCE• Polymer characterizations – contributed to the mechanistic understanding of polymer degradation processes, hydrolysis of polyesters, the photo-degradation of polyethylene coated on paper, laser ablation of polymers, and long-term stability of polyurethanes and vinyl polymers in aqueous solution.• Preparative High Performance Liquid Chromatography – significant contributions to imaging chemistry teams in Optical Medical Imaging (OMI) Agents, Organic Light Emitting Diode (OLED), Inkjet technologies and other imaging materials with preparative purifications in over 100 projects with the isolation of trace impurities, product purifications, combinatorial separations, chiral separations, preparation of standards, and the final purification of marketed (OMI) agents.• Automation - involved in designing and implementing automated high throughput micro-scale screening techniques for color photographic chemistry. I developed expertise in dispersion technology using robotic systems, including micro-scale delivery systems for automated coating technology, automated spectroscopic analysis, data collection and analysis.• Kinetics – using various analytical techniques performed kinetic and mechanistic studies for color film chemistry and processing chemistry. During this time in the imaging mechanisms lab I measured kinetic and physical chemical properties (rate constants, pKa's, and logP values) from more than 75 compounds; this work resulted in the development of novel, timed-release chemistry that was used in Kodak films. I discovered a new chemistry, subsequently incorporated into many photographic films that increased the yield by 60%. Show less
