ID: 727835
Pennsylvania, USA
He has served as an expert witness (>200 hrs) in patent litigation cases.He has developed unique applications for custom instrumentation (food applications for dielectric spectrometry).He designed a completely automated instrument for solution characterization of polymers.
Expert has extensive experience in chromatography, characterization of materials, and instrumentation.. He has invented a few measurement devices and developed instrumentation for lab, clinical and chemical process applications. The most recent project is a complete programmable controller (hardware and software for real time instrumentation and process applications (see "DAQ2GO" on youtube.com). He has several patents (viscometers, HPLC detectors, Clinical analyses, Rheometery) and many publications in chromatography (GPC/SEC, GC, HPLC), organic chemistry, particle size and molecular weight distribution analysis. He has experience in marketing, technology assessment, R&D, product applications and development, and process control. He has worked independently, as a member of, and as a leader of interdisciplinary teams (usually a mixture of chemical and electrical engineers, software applications personnel, physicists, and technical support people.
