Nominee: Nicholas Stergiou Sponsors: Thomas A. Stoffregen, Jane Clark, Beverly Ulrich

Dr. Nick Stergiou is an outstanding candidate for consideration as a Fellow in the American Academy of Kinesiology and Physical Education. In the space of 10 years, he was promoted through the academic ranks at University of Nebraska at Omaha (UNO) to a position of Full Professor in the School of Health, Physical Education, and Recreation. He has been consistently active as a teacher, a mentor, a scholar, and a contributor to the local community and to professional organizations within Kinesiology. Dr. Stergiou has published over 100 peer-reviewed papers, presented over 300 talks and posters at national and international conferences, and secured more than $8,000,000 in external grants. He currently holds the Isaacson Professorship at UNO and in 2008 received the UNO award for Distinguished Research.

Dr. Stergiou’s research ably straddles the boundary between basic and applied. He is the most important researcher working to introduce techniques of nonlinear dynamics and dynamic systems to clinical movement science. He has an extraordinary grasp of the theoretical and mathematical underpinnings of nonlinear dynamics and, more than anyone else, he has demonstrated (again and again) how these techniques can (and should) be applied to posture and gait in a wide variety of clinical populations. Put simply, Dr. Stergiou has shown the clinical movement community how and why nonlinear dynamics are important in the diagnosis and treatment of clinical conditions. Examples include “A nonlinear dynamic approach for evaluating postural control: new directions for the management of sport-related cerebral concussion” (2005), with Dr. Stergiou as senior author, and “Optimal movement variability: a new theoretical perspective for neurologic physical therapy”, by Stergiou et al. (2006). Each of these papers has been cited more than 25 times. He is one of the few non physical therapists on the Editorial Board of the Journal of Physical Therapy.

His work is not limited to clinical settings, as exemplified by his 2003 paper with Regina Harbourne (a previous graduate student), “Nonlinear analysis of the development of sitting postural control”, which has been cited more than 30 times. Harbourne and Stergiou applied several types of nonlinear analysis to the spontaneous postural activity of infants as they learned to sit. This study was instrumental in demonstrating that these sophisticated analytic techniques could successfully and rigorously (and usefully) be applied to the fine details of posture in a population for which the collection of quantitative postural data is notoriously challenging. The significance of his contributions to infancy research is the more remarkable given that Nick is not primarily a developmentalist.

Dr. Stergiou’s work is highly collaborative, as shown by the fact that he currently is involved in more than 20 collaborative relationships with colleagues in the US and internationally. His research interests include the biomechanics of running shoes, the consequences of ACL surgical reconstruction, the development of robotic laparoscopic surgical techniques, and even the biomechanics of throwing techniques in judo. His principal interest is in gait, focusing on gait dynamics and variability. He has developed and demonstrated analytic and assessment techniques for gait in athletes, clinical populations (e.g., peripheral arterial disease), and the elderly. His application of nonlinear dynamics to these populations provides novel insights into clinical disorders and assessment, but also increases our insight into stability and instability as general phenomena in movement science. There is ongoing debate about the nature and definition of stability and instability in human movement, and Dr. Stergiou’s research provides essential breadth and “real world” grounding to this debate. He is truly in the forefront of new developments in kinesiology and his research generates a multitude of new ideas and debates around the world.

Dr. Stergiou’s mentoring bears special mention. He has chaired more than 30 MA and PhD committees and currently is mentoring four post-docs and ten doctoral students. One of these, Dr. Leslie Decker, has received a K99/R00 award from the NIH, with Dr. Stergiou as sponsor/mentor; this is the first K99/R00 ever awarded in the state of Nebraska. One of his doctoral students, Sara Myers was the first at UNO that received an F31 award from the NIH. In 2008, Dr. Stergiou was named a UNO outstanding graduate mentor, a rare honor that is granted to only one person at UNO each year. He is also a mentor to junior faculty, and has recently accepted an appointment as Coordinator of Research in the UNO College of Education, where his focus is on mentoring junior faculty in the development of research programs and grant proposals. He has seen his laboratory grow from one small room into the Nebraska Biomechanics Core Facility which last year received the Chancellor’s medal for Academic Excellence.

If inducted, Professor Stergiou would bring to the Academy his reputation as an outstanding scientist, scholar, and an individual who is a leader and innovator. His contributions to Kinesiology as a field are exceptional, and his ability to interact with members of the Academy would be enormously beneficial as we move into the 21st Century. Professor Stergiou will be a willing participant in Academy meetings and we are convinced that he will work to further the goals of the Academy. We therefore recommend to the Active Fellows that they vote to induct into the Academy Professor Nick Stergiou.

small room with one graduate assistant to the facility it is now. Currently, the facility occupies a large space measuring 110 feet by 50 feet with 20 foot high ceilings. Within the laboratory are 12 graduate student offices, one post-doctoral associate (3 more such associates have offices within 50 meters from NBCF), a lab technician office, 4 undergraduate offices, and private changing room. The facility contains three motion capture systems, several force platforms, an instrumented with force platforms treadmill, an instrumented with force platforms stairway, wireless 16-lead EMG, custom virtual reality environment, and several other large pieces of equipment.
