EDUCATION/INTERESTS:

(1996) B.S., Western Kentucky University, Bowling Green, KY, M.S.E. and Ph.D., Macromolecular Science, Case Western Reserve University, Cleveland, OH; Industrial experience with Empire Berol Corp., GE Plastics, Dow Chemical Co, Allied Chemical Co. and Story Chemical Co. Dr. Patterson has taught: Topics in Physical Science (PSCI 1030), Chemistry for Consumers (CHEM 1030), Introductory General Chemistry I (CHEM1011), General Chemistry I (CHEM 1110), Polymers, an Introduction (CHEM 4700/5700), Polymer and Materials Laboratory (CHEM 4780/6780), and Introduction to Commercial Engineering Resins (CHEM 6110), Advance Topics in Organic Chemistry (Chem 7110).

Dr. Patterson's research interest covers the following areas: conducting polymers, development of non-halogenated FR compounds, bio-synthesis of polymers, synthesis and characterization of high performance polymers, structure-property characterization of engineering resins, and the effect of processing conditions on polymer physical properties, polymer blends, polymer composites and polymer design via computer modeling. Some of the tools that we use to characterize these polymeric systems are Atomic Force Microscopy, FT-IR, FT-NMR, thermal analysis techniques, dynamic mechanical analysis, viscosity measurements (solution/melt rheology), molecular weight determination, and mechanical properties testing.

With the assistance of faculty members from the Chemistry and Physics departments, a NSF-MRI Grant was awarded for the acquisition of a Differential Scanning Calorimeter, Atomic Force Microscope with micro-Thermal Analysis capabilities and a Dynamic Rheometer with solids capabilities ($192,000). The university has provided funds from the acquisition of a tensile tester and a stereo microscope ($53,000) and replacement of our Thermal Gravimetric Analysis instrument (~$55K). Through the departments instrument budget a Fluorescence Spectrometer was purchased (~$25K)
