"I decided to move to University of Arkansas, Fayetteville from OSU (Oklahoma State University, Still Water) after I visited the campus and met with Dr. Kraig Olejniczak. He was part of the faculty at the Electrical Engineering Department working alongside Dr Juan Balda. I also got the opportunity to meet Dr. Balda. The two of them were involved in cutting edge research and I thought I would have the opportunity to learn a lot from their guidance and Dr. O's tutelage. The most significant event in my life that instilled confidence in me was the constant encouragement, trust and the opportunities that I was provided by my professors and the school of engineering. I was provided all the equipment and the tools needed for my research, the teaching went far beyond focusing on the professional aspects of being an engineer, but also prepared me for my personal life. Humility, communication (I still remember my mentor and my professor Dr. Olejniczak correcting my thesis and documentation and providing feedback on my written skills, as he was a stickler for grammar), ability to scale, thinking beyond the norm, encouragement and not accepting "no" for an answer and teaching me to dream big were some of the few things that this great institution, the faculty and especially my professor taught me. I am indebted to the University and the School of Engineering for what I have learnt during those years. I admire the Engineering leadership for being able to hand select and pick some of the best engineering minds in the Country to encourage and create the next generation of engineers.


The education and the experience were extremely valuable and gave me the confidence and the courage to start embedUR. We have a come a long way in the last 10 years and we have a lot more to do and to give back to the community and back to UofA."  -Rajesh




Walter Keller

John Walter Keller Jr.
Helped to Design the First Heart Pacemaker.
BS Electrical Engineering in 1946, M.S. Math in 1948, & M.S. Physics in 1950


John Walter Keller Jr.'s professional life throughout the second half of the 20th entury in many ways tracks the progress of American engineering technology durng that time. When he retired in 1985 from his longstanding position as adjunct Professor at the University of Miami, he concluded a career spanning almost 50 years of engineering innovation.

Graduating from the University of Arkansas in 1948, Walter took a job as Electronic Engineer at the U.S. Naval Research Laboratory in Washington, D.C. He was quickly singled out for assignment in the South Pacific, where he participated in research related to Operation Sandstone and Operation Greenhouse, key components of the American nuclear test series being conducted at that time.

Following several years with the Naval Research Laboratory, Walter joined what was then known as the Harry Diamond Laboratories at the U.S. National Bureau of Standards as an Electronic Physicist. Today known as the Army Research Laboratory, this facility housed research on proximity fuses for guided missiles, including nuclear-capable rockets. Entrusted with some of the most technically sensitive research of his time, Walter Keller spent five years at U.S. NBS before leaving government service to work in industry.

In 1959 he took a position with Cordis Corporation, where his career took a decidedly different turn. There, as Staff Physicist, he helped to develop a pacemaking program that would eventually yield the world's first implantable remotely programmable digital pacemaker. While the concept for such technology was widely known and discussed, Walter's contributions to Cordis' "Atricor" device helped enable the first prosthetic device to automatically control a physiologic parameter. This innovation dramatically altered life for the hundreds of thousands of patients who would ultimately benefit from this implantable device and its technological descendants.

From 1969 to 1985, Walter built on his early breakthroughs in medical engineering to create a successful career in biomedical engineering that included organizing a Biomedical Engineering Depatment at the Miami Heart Institute, serving as Vice President for ESB-Medcor (a pacer systems company), and working as an independent consultant to numerous biomedical firms in the cardiac space.

Walter holds a bachelor's degree in electrical engineering and two master's degrees - in physics and math - from the University of Arkansas. From 1958 to 1985 he served as an Adjunct Professor at the University of Miami in Florida. He has been recognized as a Distinguished Alumnus by the University of Arkansas Alumni Association (1991), the University of Arkansas at Little Rock (formerly Little Rock Junior College) (2001) and by Little Rock Catholic High School. He lives with his wife of 56 years, Jinny, in Tequesta, Florida. Together, they have 12 children, 7 grandchildren and 4 great-grandchildren.

Neil B. Ingels
BS in Electrical Engineering in 1959, MS in Electrical Engineering in 1963, PhD in 1967
Head, Laboratory of Cardiovascular Physiology and Biophysics Research Institute
Palo Alto Medical Foundation
Palo Alto, California

In 1959, Dr. Neil Ingels received his bachelor's degree in electrical engineering from the University of Arkansas. After graduation, Neil moved to Utah, and then California, where he worked designing guidance and control systems for space vehicles.

In 1962 Neil accepted a position at the Palo Alto Medical Research Foundation in Palo Alto, California. He completed his master's degree in electrical engineering at Santa Clara University and received his PhD in electrical engineering at Stanford University in 1967 while working in heart research, the field he continues to pursue today. At this time he developed an x-ray method to measure the dynamics of the heart which proved to be the most accurate method for such measurements and continues to be used in his laboratory at Stanford University to the present day. He became Chairman of the Department of Cardiovascular Physiology and Biophysics at the Palo Alto Medical Research Foundation and Associate Professor of Electrical Engineering and Professor of Cardiovascular Surgery at Stanford University.

Neil has authored more than 400 publications and presentations and four books. His work has helped the world to understand the complex workings of the heart and its valves and has influenced the way heart operations are performed. He was elected to membership in the Arkansas Academy of Electrical Engineering in 1981, became an Adjunct Professor of Biological and Agricultural Engineering at the University of Arkansas in 2003, is a Charter Fellow of the American Heart Association and the Biomedical Engineering Society and was recently awarded an honorary Doctorate from Linkoping University in Sweden.
