Dr. Ryan’s research focuses on examining the influence of various acute and chronic stressors on neuromuscular function. Most recently, our team has specifically worked to mitigate injuries and improve occupational health and performance in first responders. Dr. Ryan has published over 120 peer-reviewed original research manuscripts and has lectured nationally on the research conducted with his team. An example of his current work can be found here.

Hayden Giuliani, MA
M.A., The University of North Carolina at Chapel Hill
B.S., Waynesburg University
Hayden Giuliani completed her MA in Exercise Physiology at the University of North Carolina at Chapel Hill and her BS in Athletic Training and Exercise Science at Waynesburg University in Pennsylvania. Under the direction of Dr. Eric Ryan, Hayden examines neuromuscular function, specifically the influence of muscle quality on measures of strength and function. Additionally, she is interested in investigating workload within tactical populations in relation to injury risk and job performance. In her free time, she enjoys hiking, lifting, and trying new coffee shops.
Evangeline Soucie, BS
B.S., University of Kentucky
Evangeline graduated from the University of Kentucky where she gained experience in the Exercise Physiology Lab and became interested in neuromuscular physiology. More specifically, she is interested in the neuromuscular responses to resistance exercise and different fatiguing protocols. She is currently pursuing her Masters degree under the mentorship of Dr. Eric Ryan and hopes to pursue a PhD in Exercise and Sports Science upon graduation. Some of her hobbies include rock climbing, long boarding, and playing card games.
James Merritt, BS
B.S., East Carolina University
James is originally from Chapel Hill and completed his Bachelors of Science in Exercise Physiology at East Carolina University. He is interested in studying muscle recovery and regeneration in sports, and his future research goal is to be able to study the effects of neurodegenerative diseases on muscle performance.
Adam Coleman, BA
BA, University of North Carolina at Chapel Hill
Adam Coleman is from Wilmington, North Carolina and graduated from UNC Chapel Hill with a degree in Exercise and Sport Science. Here at UNC he will be working under the guidance of Dr. Eric Ryan in the Neuromuscular Assessment Lab to conduct research in tactical populations. Outside of school, Adam has worked as a Firefighter and Ocean Rescue at Wrightsville Beach, North Carolina for the past four years. In his free time, he enjoys swimming, resistance training and hiking.
