Concordia College

Majors in Chemistry and French.  I taught English at a French school and lived with families for several months during my senior year at Concordia College.

Work experience

Jan 1996Present


LNS Consulting Services

Providing guidance in the selection of materials for medical devices, electron beam and gamma radiation sterilization and processing, manufacturing problem solving, project management, and market research.  Areas of expertise:  Product and process development, polymer structure/function properties, radiation chemistry and processing, polymer and organics characterization and analysis, thin film coatings, adhesion-promoting surface treatments, and patents. 

My most recent projects involved researching a new food additive and investigating a new program for a local university. 

Examples of projects include:  Provided business development services to a Canadian company for electron beam sterilization and processing services.  Involved in customer visits and presentations about the technology and steps for product qualification and process validation.  Responsible for advertising and trade shows in the U.S.; Conducted several market research projects to analyze the medical device market in Minnesota; Invited to give a presentation entitled "Designing Medical Products for Electron Beam Sterilization" at several Minnesota-based medical device companies; Developed a set of tutorials about electron beam processing and radiation effects on materials for a large medical device company.

Additional projects include:  Designed and managed a set of experiments to determine the dose and product temperature needed to electron beam sterilize a collagen-containing medical device.  This work involved the pre-cooling of product cases and the real-time measurement of product temperature duing processing; Worked with several start-up medical device companies to determine the optimum radiation sterilization conditions for their protein or tissue products.
