Cody Haun

Cody Haun completed his Bachelor's and Master's Degrees at East Tennessee State University where he studied Exercise and Sport Physiology alongside his work as a strength and conditioning coach. During this time, Cody developed a keen interest in physiology and nutrition. Cody went on to complete his PhD from Auburn University with a concentration in Exercise Physiology where his research focused on the physiology of muscle growth and nutrition in the Molecular and Applied Sciences Laboratory under the mentorship of Dr. Michael Roberts. After completing his PhD, Cody continued his scientific research and served as an Assistant Professor where he taught undergraduate and graduate courses in Exercise Science and Nutrition. In 2019, Cody founded Fitomics—a company dedicated to using the latest scientific research to help individuals improve their health, performance, and physique. Cody currently serves as the Chief Executive and Science Officer of Fitomics where he works with a diverse and talented team of Medical Doctors and PhDs that share a passion for helping people apply scientific research findings to practice. Cody holds the Certified Strength and Conditioning Specialist (CSCS) credential through the National Strength and Conditioning Association and is an Accredited Sports Nutritionist through the Sports Nutrition Association. Over the past decade, Cody has published in several prestigious academic journals and successfully worked with 100s of clients both online and in-person to improve their health and performance. Cody is passionate about helping people appropriately apply science to practice and is excited to continue these efforts through his contributions to REPS with the mission of explaining research via practical summaries.
