Summary of Expertise: Listed with other top experts in: 
Expert has significant experience in the development of photoresists and ancillary products (such as developers and strippers) for applications such as semiconductor fabrication, lithographic printing plates, silk screen printing, and photofabrication, including color cathode ray tubes. His research led to a number of commercial positive and negative photoresists. He has worked in the areas of diazo-oxide chemistry, diazo resins, photopolymers, and photosensitive polyimide precursors.

Expert has developed light-sensitive compositions for negative and positive tone lithographic and letterpress printing plates including CTP. His research in diazo-oxides, diazo resins, and photopolymers for the lithographic plate application resulted in commercial products of improved properties.

Expert has been active in the development of non-silver halide imaging systems. He is knowledgeable in the area of stable colorless dye precursors, particularly leuco triphenylmethanes, their conversion to dyes with photo-oxidants, and methods to prevent dye formation of dye precursors and photo-oxidants.

Expert has developed methods of imaging by ink jet lithographic printing plates that contain diazo resins and naphthoquinone diazides. Based on this development commercal CTP systems have been developed. In addition he has investigated methods of producing lithographic plate images that eliminate development or can be water/on-press developed.
