Expert has extensive experience in characterization of materials and property measurements, especially those related to molecular weight, molecular architecture, and material composition. He has several patents in related areas (viscometers, HPLC detectors, Clinical analysis of Blood and vital fluids) and many publications in chromatography (GPC/SEC, GC, HPLC), dielectric spectrometry, particle size and distribution analysis. In addition to inventing a few measurement devices, he has developed many instruments and applications for them. He has also supported marketing activities in the area of laboratory and process instrumentation. He has work experience in marketing, technology assessment and development, product applications and development, and process control. He has worked independently and as a member of many interdisciplinary teams (usually chemical and electrical engineers, software applications personnel, physicists, and technical support people.

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.
