Andrei S. Dukhin is CEO and Co-Founder of Dispersion Technology, Inc., USA. He has been a leader in the development of a new technology for characterizing complex liquids that employs ultrasound for characterizing interfacial chemistry, particle size, and rheological properties of said systems. He has authored three books published by Elsevier, most recently Characterization of Liquids, Nano- and Microparticulates, and Porous Bodies using Ultrasound with Philip J. Goetz back in 2010. He holds 7 USA patents on electroacoustic methods of measuring zeta potential and has published more than 120 scientific papers. He established Dispersion Technology Inc, which installs more than 850 instruments for measuring zeta potential in 30 countries.Philip J. Goetz has an Electrical Engineering bachelor degree (MIT) and an MS in Computer Science (New York University). Between 1960–1970, he was an Engineering Group leader developing doppler radar technology for military airborne navigation and image recognition hardware for airborne terrain guidance. He has been President, chief scientist and founder of a new venture for developing electro-optical instrumentation for characterizing the zeta potential of dilute colloids. From 1996 – 2010 he was Chairman and co-founder of Dispersion Technology for the development of ultrasound instrumentation for complex characterization of concentrated colloids.
