Research Concentrations

Image Processing; Neural Signal Processing

Research Accomplishments and Activities

Super resolution of images using sequences of images; Neural signal processing - Spike sorting; Low bit rate speech coding

Research Philosophy

Research has as an objective not only to uncover entirely new domains, but also to improve on current solutions. A researcher should always ask "How can I do it better?" about his and others' work. In the processes of doing incremental improvements, truly new creations emerge too.

Courses Taught

EE 2370: Design and Analysis of Signals and Systems; EE 3372: Introduction to Digital Signal Processing; EE 5374/7374: Digital Image Processing; EE 8373: Digital Speech Processing

Panos Papamichalis has been a Professor of the Electrical Engineering Department at SMU since August 2003. Before that, he spent 23 year with Texas Instruments (TI), between 1980 and 2003, where he became a TI Fellow.

While at TI, Dr. Papamichalis served as the Director of Texas Instruments’ Imaging & Audio Lab within the DSP R&D Center in Dallas, and as the Director of TI’s Tsukuba R&D Center, in Tsukuba, Japan. From 1984 to 1990, he was a Senior Member of Technical Staff at the Texas Instruments DSP Applications group in Houston, Texas. He was responsible for developing applications of DSP algorithms on programmable DSP processors. He has also served as an adjunct professor at the University of Texas at Dallas, and at Rice University in Houston.

Dr. Papamichalis is an IEEE Fellow. He served as the 2000-2001 President of the IEEE Signal Processing Society. He was the General Chairman of the 1987 International Conference on Acoustics, Speech, and Signal Processing in Dallas, and was selected as a distinguished lecturer of the IEEE ASSP Society of 1989. Between 1990-96 he served as Vice President-Conferences of the IEEE Signal Processing Society. In 1996, he received Signal Processing Society’s Meritorious Service Award, and in 2000 he received the IEEE Third Millennium Medal.

He is the author of the book “Practical Approaches to Speech Coding”, (Prentice-Hall, 1987) and the editor of volumes 2 and 3 of “Digital Signal Processing Applications with the TMS320 Family” (Prentice-Hall, 1990). Dr. Papamichalis holds four patents in the area of speech coding, and has published many papers on speech processing and digital signal processing. He is a member of Sigma Xi, HKN, and the Technical Chamber of Greece.
