Roger Pearson Email & Phone Number

Dr. Pearson began working for Aspen Research in 1996. Immediately prior he held a post doctoral position with the University of Minnesota’s School of Public Health studying the cycling of bio-accumulative organic chemicals in the Great Lakes. He has a dozen peer reviewed articles pertaining to that subject.Roger co-owned and managed a restaurant in the Twin cities for six years. Prior to his restaurant endeavors, he worked as a research chemist and then as a production superintendent for Celanese Chemical Corporation (1977 – 1983). As a chemist with Celanese, he had responsibilities for optimizing numerous chemical processing operations and developing new process techniques. As a production superintendent he was in charge of 700 million pounds per year of chemical production (acetyls and esters) with an operating budget of $150 million per year.Roger has extensive experience in gas chromatography analysis of volatile and semi-volatile compounds and is an expert at coupling analytical results back into process chemistry. He is an industry recognized expert in Extractables and Leachables techniques and has coordinated many studies of off gassing phenomena at elevated process temperatures. His studies have been instrumental in assisting risk professionals in providing guidance for companies navigating in various regulatory arenas.In addition to Roger’s chemical analysis expertise, he also guides Aspen’s materials research and development efforts. His efforts here have been key in aligning Aspen’s internal expertise with market and material opportunities and streamlining the process of characterizing newly designed materials by taking advantage of Aspen’s unique R&D model, “materials R&D and complete analytical services, all under one roof”.Roger holds both an M.S. and Ph.D. in environmental chemistry from the University of Minnesota and a B.S. in chemistry from Montana State University.Specialties: Matererials R&D InvestigationsExtractables & Leachables StudiesOff Odor StudiesElevated Temperature Off Gassing Studies
