Expert has worked in the coatings industry for 3 years prior to working at a large petrochemical company for 6 years. After that he spent another year and 3 months working for a large polyolefin company in Austria. During this time the expert has published significantly on areas that involved controlled free radical polymerization as well as novel polyolefin synthesis, notably LLDPE. He has applied controlled free radical polymerization successfully in all three companies. The author has extensive knowledge on polyolefin characterization (PP and PE) as well as ways to process these materials. In the coatings industry the author has extensive knowledge in the area of decorative paints. The author has a lot of experience in experimental design and optimization, statistical data analysis and mathematical modelling of polymerization kinetics. In addition to commercial polymers such as PP and PE the author is well acqainted with the application of controlled free radical polymerization in pharmaceutical and medical fields such as drug delivery and the author has modelled the physics of slow release polymer systems with great success. With regard to polymer characterization the expert has hands-on experience with tensile testing, impact testing, GC and HPLC, DSC, TGA, DMA NMR and FTIR in both polymer characterization as well as general chemistry. With regard to general chemistry he is expert in organic, physical, inorganic and analytical chemistry. In terms of CO2 chemistry he is well aware of all the major chemistries including solvent selection and the type of bases required. He has has also ventured into the use of nano technology for the development of early detection of pathogens and new catalyst development especially in the area of Fischer-Tropsch catalysis.
