Richard (Rick) L. Lieber (born December 14, 1956) is an American scientist in the field of muscle physiology who is an internationally recognized expert in skeletal muscle structure and function. His research focuses on skeletal muscle properties in individuals with neurological disorders such as spinal cord injury or cerebral palsy to identify targets for therapeutic interventions.




Early life and education


Dr. Lieber was born in Walnut Creek, California, the son of a big band musician and hospital administrator. He completed a B.S. in physiology in 1978 at University of California, Davis. In 1983, he earned his Ph.D. in biophysics from University of California, Davis, applied a theory of light diffraction to study mechanical properties of muscle cells and was one of the first to use the Intel 8080 microprocessor to control a biological system in real-time. He received his M.B.A. in 2013 from Rady School of Management, University of California, San Diego.




Career


Lieber started his career as a Biomedical Engineer at the Veterans Administration Medical Center (1983) and then started in academia at UC San Diego (1985). Notably, he holds the position of Chief Scientific Officer at Shirley Ryan AbilityLab (formerly the Rehabilitation Institute of Chicago), a nationally recognized translational rehabilitation research hospital.




Research


Lieber has published over 350 articles in peer-reviewed scientific journals ranging from basic science such as The Journal of Cell Biology to clinical research such as The Journal of Hand Surgery. He is an established expert in using biological approaches to understand muscle contractures in neurological conditions such as cerebral palsy, stroke and spinal cord injury. Lieber's work includes the development of pharmacological and surgical interventions to improve muscle function in individuals with neurological conditions. He has made significant contributions to the field of muscle physiology in the area of in vivo muscle measurements, and he is highly referenced in scientific journals. His most often cited paper is "Functional and clinical significance of skeletal muscle architecture" in the peer-reviewed journal Muscle & Nerve with 1447 citations. His work has over 34,000 citations in the scientific community and his h-index is 91. In addition to his publications in peer-reviewed journals, he authored the textbook, "Skeletal Muscle Structure, Function, and Plasticity," which explores basic and applied physiological properties of skeletal muscle.




Distinctions


Lieber's career is marked by significant professional collaborations with international colleagues and organizations, including Jan Fridén, M.D., Ph.D. at Gothenburg University, Eva Pontén at the Karolinska Institute, and Allistair Rothwell at Christ Church, New Zealand.
Lieber also serves as a member of the scientific advisory board of the NFL and has six patents on surgical techniques, methods to measure muscle fibers, and methods to administer stimulation to skeletal muscles
