Current areas of specialization include research, development, analysis and understanding of digital signal processing algorithms. Ongoing research efforts are directed toward improving understanding and performance of algorithms used in speech recognition, pattern detection and recognition, noise removal and enhancement of speech and image data using human hearing and visual models.
March 1978 to August 31, 1978 -- Chief Scientist, Eyring Research Institute.
October 1, 1976 to March 1978 -- Director of the Applied Sciences Division of the Eyring Research Institute. Responsible for the technical and administrative management of all projects in the division. Some of these projects include low frequency antenna studies, High Energy Plasma Phenomena Study, Hyperspace/Predictive Techniques Research, Radiation Hardened Semiconductor Development Project, etc.
September 1974 to October 1976 -- Research Associate Staff member, Electrical Engineering Department, University of Utah. Responsible for conducting a two-year research effort in automatic word recognition in continuous speech using digital computer analysis. Techniques used included communication theory principles, nearest neighbor pattern matching, nonlinear time warping, linear prediction analysis of speech, Wiener filtering to extract speech signal from speech plus noise, and spectral analysis using Fast Fourier Transform and Linear Predictive Coded smoothed frequency spectrum. During this time, also worked on a contract with Hill Air Force Base as a consultant to propose changes and provide evaluations of the program to maintain the Electromagnetic Pulse hardness of the Minuteman Weapon System. This effort used the experience gained previously at EG & G. Supervised an experiment to produce laser x-rays using a high energy neodymium glass laser.
September 1, 1972 to September 1974 -- Software Sciences Corporation, Manager, Salt Lake City Operations. Responsible for all technical and administrative activities at the Salt Lake City operations. Program Manager on all major technical programs at Salt Lake City, including hardware and software.
January 1, 1969 to September 1, 1972 -- Employed by EG&G, Albuquerque Division, as Scientific Specialist. During this time, had the following responsibilities:
Digital signal processing, communication theory, information theory, neural network models applied to pattern recognition and analysis.
Ongoing research has been directed toward:
Author or Co-author of over 40 technical publications some of which are listed below.
