At Bell Telephone Laboratories, did research on ambient underwater noise and modeling of acoustic properties of multi-layer strata. At MIT, developed speech synthesis-by-rule systems and developed algorithms for generation of segment durations for speech synthesis. At Georgia Tech, has been heavily involved in research, curriculum development, teaching, and laboratory development. In research, has done internationally recognized work in speech coding, objective measures for speech quality testing, multiprocessor architectures for digital signal processing, and digital signal processing algorithms. In curriculum development, has introduced five new courses in digital systems, speech theory, and multiprocessor architectures for digital signal processing. In laboratory development, founded the Digital Signal Processing Laboratory (now the Center for Signal and Image Processing) and procured over five million dollars in equipment over a twenty-seven year period. In research administration, has procured and managed about thirty research and equipment grants, and has directly supervised the activities of the three engineers and two technicians associated with the Digital Signal Processing Laboratory. In telecommunications standards, won the 1996 competition for the 2400 BPS Federal speech coding standard.

 As an entrepreneur, was a co-founder of Atlanta Signal Processors, Incorporated (ASPI), and has been involved in the development of all aspects of the business. As president, had primary responsibility for the operation of the company, including new product development, manufacturing, sales, marketing, office functions, and customer support. ASPI has been a pioneer in the area of digital signal processing technology, and ASPI's products include hardware and software tools for DSP algorithm development and multimedia on high-speed DSP microprocessors.
