This Ph.D has over 35 years of experience in telecommunications and signal processing.  He has published one hundred and thirty papers and 5 books, and is the author of thirty-five patents.  He has also testified at trial and depositions for patent infringement matters.  His personal research has been in the field of digital coding and transmission of information signals.  This work has led to pioneering techniques for adaptive quantization and ADPCM coding, which have been incorporated in international CCITT standards for low bit rate voice and digital audio. His research has also defined techniques for speech encryption, packet voice, signal enhancement, robust vector quantization and image coding.  He was the first editor-in-chief of the ASSP Magazine, a publication of the Acoustics, Speech and Signal Processing Society of IEEE. 

The businesses created by his research and leadership, span several segments in audiovisual and data communications.  These businesses include low bit rate speech CODECS for digital transmission, multiplexing, cellular telephony and AUDIX voice storage; high-quality audio coding for teleconferencing and advanced DAT; video coding for advanced television, internet video and voice band video telephony; and high-density magnetic disks for computer data. Other emerging businesses include natural language call centers, systems for message translation and filtering, set-top boxes, solid-state multimedia players and recorders, DVD systems, CD-quality broadcast receivers and Internet Multimedia.
