Biography

I was born and raised in Wichita Falls, Texas, and went to college at Midwestern State University in the same town. I graduated in 1966, got married (Stella Lang), and we both started graduate school at Purdue University. I received my Ph.D. in Physics at Purdue in 1970 concentrating in low energy experimental nuclear physics. That was followed by a two year post-doctoral fellowship at Florida State University. I went from there to Rhode Island spending approximately eleven years in the Rhode Island Hospital Department of Radiation Oncology and Brown University. My primary focus there was on the development of computer support applications for radiation therapy. I was an early contributor to the ideas of interactive three-dimensional treatment planning graphics including beam’s eye view and the use of bit-mapped color display for visualization of anatomy and radiation beam placement.

In 1984, I joined the Department of Radiation Oncology and continued work on computer applications in radiation therapy. Along with Dick Fraass, we developed the first complete interactive three-dimensional treatment planning system (called UMPlan) for photon, electron, and brachy (implant) therapies. Over the years since, I have worked on continual improvements to that system (still in clinical use in 2012). Also, time was spent developing a system for interfacing with one of the first treatment machines (Scanditronix Racetrack) with computer controlled multi-leaf collimator and motion control. That control system was also adapted to work with other treatment machines in the department. I have worked on integrating radiation dose calculation algorithms (convolution superposition and Monte-Carlo calculations) and on intensity modulated optimization system
