Tyler Barker, PhD, graduated from the University of Utah prior to receiving his MS and PhD degrees from Kansas State University and Oregon State University. During his dissertation work at OSU and The Linus Pauling Institute, he studied the influence of vitamins E and C on oxidative/nitrative stress, inflammatory cytokines, and skeletal muscle dysfunction (size and strength) in patients undergoing anterior cruciate ligament surgery. From this experience, he developed a passion for the application of basic research findings in redox and inflammatory biology to the clinical and physiological settings. He has applied this passion to our long-term research objective of identifying the medical implications of reactive oxygen/nitrogen species and inflammatory cytokines on clinical- and research-based outcomes. He is currently conducting several studies examining the influence of vitamin D on inflammation, redox biology, and clinical outcomes on diverse conditions in elderly and young adults.   
Bill McDermott, PhDBill McDermott, PhD, received his undergraduate degree in Biology from Ramapo College of New Jersey and his MS (Motor Control) and PhD (Motor Control/Biomechanics) from the University of Massachusetts. His specific areas of research focus on the etiology, prevention, and recovery of lower extremity injuries; the interplay between movement mechanics, economy, and overuse injuries; and the adaptations that are made to movement control in response to various factors that include pain or weakness following surgery, total joint replacements, or using a prosthetic device.​
