    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

    Lehigh Carbon Community College

    Adjunct Instructor

    Northampton Community College

    Research Associate

    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.

    Mobay Corporation (now Bayer MaterialScience)

    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.\n\n\tAdvanced RIM Technology\n•\tEmployed 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;\n•\tCo-inventor of the internal mold release agent commercialized for Bayflex 110 polyurethaneurea RIM systems used in automotive fascia;\n•\tInvented 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;\n•\t 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; \n•\tInvented a new and novel polyol for polyurethaneurea RIM which did not require the use of tin catalysts

    thus improving thermal stability; \n\tServed as Technical Recruiter for the Polyurethane Division

    assigned to Cornell and the University of Rochester; \n\tTaught a one-semester internal course in Organic Chemistry for Chemical Technicians at Mobay; Book used: “Organic Chemistry

    a Brief Course”
