Taught Chemistry in the Community and Chemistry at Southfield High School.
Fall ‘04 to Present
Short-term science and math in high schools. Long-term math and language arts at Clara B Ford School on the campus of Vista Maria since November '04. Two classes are taught as team with another teacher. This school attends to the educational needs of court-supervised girls suffering from various forms of abuse and neglect. Many are learning disabled, emotionally impaired.
1998 to May 2005
Volunteer Tutor, BOARD HOST, Ask-A-Teacher Homework Help Service As a sanctioned volunteer, explain concepts behind chemistry questions posted on boards. Remove inappropriate posts as board manager.
March 1996 to May 2000
Manager, Nutrition and Cosmetics R&D. Developed high capacity spray-dried vitamin powders. Found ways to formulate gluten as a possible inexpensive carry for fat-soluble vitamins.
March 1992 to February 1996
Senior Manager, Process Development and Scale Up, a 13-person department comprised of process engineers, chemists, non-degreed professionals, and operator/technicians. (Three more operators to be added in '96 to meet small-production demands.) While maintaining a three-shift, 24-hour lab and pilot-plant operation, responsible for scale up of new processes, optimization of present ones, small-scale production, and certain sample functions. Process emphasis is in synthesis (particularly so-called natural type) and fractional distillation although responsibilities run the gamut of food processing: fermentation, emulsion, extraction (solid and liquid), filtration, pressure cooking, extrusion, coating, spray drying, and blending. Process equipment is identified, procured, setup, and run until released as regular production. Requires creativity in dealing with multi-project juggling while quickly evaluating process needs in an industry where new product success is less than five percent and product lifetimes can be short or competitive price pressure can arise in short order; need to be up and running in as short as time as possible, working out process details while producing.
Key accomplishments: Increased lab/pilot-plant output without increasing operator head count. Clearly defined the role of the group within the site operations and, in so doing, improved interaction with the rest of site. Increased capabilities through key technical personnel acquisitions. This expertise has diffused through the entire group and raised the recognition level of the group throughout the IFF technical organizations. Raised level of expertise and increased equipment capabilities in gas chromatography. Have taken a number of difficult, impractical, nightmarish processes and made them work. Some were deemed near impossible. Some work so well that IFF can effectively compete in the natural chemicals arena while enabling desirable profitability levels in spite of the heavy overhead of the organization. Active in Total Quality Management.
August 1989 to March 1992
Director, Process Development, a two-site, seven-person department in this flavor and fragrance company. Responsible for pilot-scale development of processes, synthetic and natural, from research procedures, transfer of those processes to manufacturing, production of market-introduction quantities of new products, meeting small-production needs and optimization of present processes. Increased capabilities through equipment procurement (filtration/drying) and new process approaches (molecular distillation). Provided technical guidance in spray drying. Introduced concept of statistical experimental design in optimization. Developed process/product definition procedure for clearly defining the properties and process for every product. Assumed leadership role in bringing today's concept of quality and quality management to FDO. Co- facilitator in total quality management program.
October 1987 to August 1989
Research Manager, Vitamins R&D, a five-person (three Ph.D.s) department responsible for development of vitamin formulations for function and stability along with plant support for vitamin E synthesis and vitamin E-and A-powder production. Developed crosslinked vitamin A powders for stability testing in premixes, pelletting, and extrusion. Developed HPLC methods. Designed, built, and procured testing equipment. Developed all-gelatin spray-dried 50%-vitamin E powder for tabletting. Process required development of a procedure for inexpensively modifying and controlling the molecular weight of gelatin enzymatically with monitoring via gel permeation chromatography. Used statistical experimental design in optimization.
June 1984 to October 1987
Section Head, Vitamins R&D, a five-person department responsible for vitamin formulation development for pharma, food, and feed applications along with technical-service support in animal nutrition. Developed several spray-dried formulations for Water-Soluble vitamins. Developed special spray-dried formulations for truly directly compressible products that require no excipients for direct tabletting. Assisted management of toll production of many spray-dried products. Provided plant support for vitamin E synthesis and vitamin A- and E-powder production. Assisted in customer presentations and testing at customer facilities from Saskatoon to San Juan. Developed statistical evaluation of particle numbers in products and in their applications.
October 1982 to June 1984
Research Staff Member I, Vitamins R&D. Developed heat-stabilized carotenoid formulations for cooking oil. Developed spray-dried, Water-Soluble vitamin formulations. Provided support for vitamin E-synthesis plant. Developed statistical experimental design for optimizing vitamin A-powder stability. Provided technical service support for 13-cis-retinoic acid.
Dec. 1979 to Oct. 1982
Research Staff Member II, Vitamins R&D. Provided support to new vitamin E-synthesis plant. Optimized yield providing $100,000 annual savings. Developed HPLC methods for monitoring vitamin E synthesis.
