I am currently teaching chemistry courses at the Tamaqua, PA Campus. In the Fall of 2013 I will be teaching Organic Chem I and the Lab

At Air Products I was been involved in development programs for cast elastomers, water-based release agents, catalysis for flexible PUR and rigid PIR foams, catalysts, internal mold release and chain extenders for RIM, raw materials for waterborne polyurethane and epoxy coatings and most recently, a non-polyurethane project, monomers for 157 nm photoresists.

At Mobay I was a member of the Analytical/Environmental, Isocyanate and RIM Elastomer Groups. where I participated in the development of RIM systems for the Pontiac Fiero body and the introduction of internal mold release technology for automotive and non-automotive RIM systems.

A Research Specialist in the Isocyanate Group with the Polyurethane Research Department, functioning as liaison to the RIM Applications and Development Group from Polyurethane Research and responsible for new developments in Mobay’s RIM technology as the specialist in charge of the laboratory-scale RIM machine. Also responsible for coordinating and developing internal mold release technology for non-automotive RIM, shoe soles and semi-rigid foam. Advanced RIM Technology• Employed Statistical Design Experiments and Regression Analysis to formulate the Bayflex 110-80 RIM system which was commercialized for fenders and door skins on the Pontiac Fiero;• Co-inventor of the internal mold release agent commercialized for Bayflex 110 polyurethaneurea RIM systems used in automotive fascia;• Invented and patented a completely different internal mold release agent for Baydur structural RIM systems which could not use the system developed for elastomeric RIM; This new release agent was also commercialized;• Conducted an extensive program on isocyanate prepolymer structure as it affected freeze stability, reactivity and ultimate RIM physical properties; This expanded Mobay’s patent estate at a time when patents on staple products were about to expire; • Invented a new and novel polyol for polyurethaneurea RIM which did not require the use of tin catalysts, thus improving thermal stability;  Served as Technical Recruiter for the Polyurethane Division, assigned to Cornell and the University of Rochester;  Taught a one-semester internal course in Organic Chemistry for Chemical Technicians at Mobay; Book used: “Organic Chemistry, a Brief Course”, W.W. Linstromberg and H.E. Baumgarten, 5th Ed., D.C. Heath and Company;
