Career Experience

Following my graduation with the B.S.E.E. degree, I went to work for Texas Instruments, Inc., (TI) in Dallas. Two years of that time were spent as a field engineer in Germany attached to 7th Army forces there running a maintenance facility for a classified high-resolution Ka-band side-looking airborne reconnaissance radar system (APQ-86 in RU-8D Beechcraft aircraft). Upon returning from Germany, I became a Member of the Technical Staff at TI when I joined the Simulation and Analysis Group that used digital computer simulations and analysis methods to do technical audits on design projects and to assist in the design and performance analysis of new radar systems. My experience at TI  included electronic countermeasures (ECM) projects and project leadership.

In 1972 upon completion of my Ph.D. degree in biomedical engineering, I joined the Radiology Department of the University of Texas Southwestern Medical School. I, together with my colleagues in the department, established the Radiology Imaging Center. In the late 1960s and early 70s minicomputers were coming into their own. Digital Equipment, Data General, and Prime, and others provided minicomputers for medical applications. These systems began to pervade clinical medical imaging. Our group in the Radiology Imaging Center was primarily involved in software development for interfacing  and imaging applications of minicomputers in nuclear medicine. Nuclear medicine saw the first applications of computers in medical imaging long before CAT scanners or MRI appeared. Our imaging lab developed software using bit level, assembly level, and higher level language coding. We wrote software for drivers for new equipment, and we wrote our own graphics software packages when none were available. Later in the mid-80s we progressed to post-processing methods involving image understanding techniques used as diagnostic aids, semi-automatic segmentation and display methods, and parameter extraction methods for quantifying diagnostic information in clinical imaging studies.

In the mid-80s I taught courses at the University of Texas at Arlington in the Computer Science Engineering Department. I moved my primary appointment from UT Southwestern Medical Center to UT Arlington in Computer Science Engineering in the late 80s where I was promoted to full professor in 1989. 

In 1990 I moved to the University of Alabama at Birmingham (UAB) as Chair of the Department of Biomedical Engineering where I served as chair for six years. In the mid-90s I moved to Associate Dean for Research in the School of Engineering at UAB where I retired in 2002. During this last appointment I served as Interim Chair of Mechanical Engineering.

From the mid-1990s until around 2011 I served on a number of review committees/panels for the National Science Foundation and the National Institutes of Health reviewing research and scholarship program proposals. During that time, for a number of years I also served on the Whitaker Foundation Scholarship Board where I reviewed both research proposals and also scholarship proposals for Ph.D. programs in biomedical engineering. After my retirement I provided conflict of interest site visits and reviews for a major research university and I also continued to serve on a National Science Foundation review panel.
