Personal Summary
I grew up near Dahlonega, Georgia, which is a small town nestled in the foothills of the Appalachian Mountains. My love for the outdoors has always kept me active, and I remain fascinated by our adaptive ability to respond to physiological stress. After the completion of my PhD in Exercise Science from the University of Mississippi, I sought out the best research training opportunities to study metabolism. I found that opportunity in the laboratory of the late David Wasserman, PhD at the Vanderbilt University School of Medicine. Utilizing isotopic tracers to literally trace carbohyrate metabolism during exercise, we worked in conjunction with Michael Kjaer, MD at Bispebjerg Hospital in Copenhagen, Denmark and characterized the hormonal regulation of glucose metabolism during exercise under conditions of metabolic stress. Those years of intense training provided an exceptional foundation for my career as an independent scientist.
I secured my first "real" job as an Assistant Professor of Geriatrics at the University of Arkansas for Medical Sciences (UAMS), where my research team was the first group to demonstrate the influence of exercise-induced weight loss on the reduction of visceral fat and enhanced hepatic insulin sensitivity. Soon thereafter, Robert Wolfe, PhD became the Director of the Center for Translational Research in Aging and Longevity at UAMS, He and I were the first to describe the rapid loss of skeletal muscle and physical function due to bed rest in older adults.
Motivated by my desire to establish a clinical research in Alaska, I accepted a faculty position in the Institute of Arctic Biology at the University of Alaska Fairbanks (UAF). I co-founded Essential Blends, LLC that led the state of Alaska in Small Business Innovation in Research grants from the National Institutes of Health. Utilizing these resources, we discovered that bed rest-induced perturbations were mitigated by the precise delivery of essential amino acids (EAAs). We patented these amino acid formulations and launched The Amino Company () to provide these clinically proven products around the world.
While in Alaska, I also established experimental models to study the mechanisms responsible for physiological resilience. These efforts include projects with the Alaska Mountain Wilderness Ski Classic, Yukon Arctic Ultra and Alaska Backcountry Expeditionary Hunting. Working with Mathias Steinach, MD at the Center for Space Medicine, Berlin; Dale Schoeller, PhD at the University of Wisconsin Madison and Brent Ruby, PhD at the Ñý¼§Ö±²¥ (UM) we described the preservation of skeletal muscle despite sustained negative energy balance. When my wife Sheri Coker completed her PhD in Natural Resources and Sustainability from UAF, we joined forces with Brent Ruby, PhD to examine sex-specific alterations in muscle protein metabolism during physiological stress.
I am laser focused on the pragmatic application of my research endeavors. Papers and presentations are great and fun, but impactful only when directed specifically towards improved health outcomes. We are excited to be in the great state of Montana and we cannot wait to see what the future holds for innovations in translational biomedicine!
