Dr. Lorna Doyle is a lecturer in Nutrition in the Dept. of Health Sport and Exercise Science at Waterford Institute of Technology. Dr. Doyle completed her BSc Ed at University of Limerick and continued to further her education by completing her MSc and PhD in the area of Clinical Nutrition at UCC. She is a registered nutritionist with nutrition specialism in Sport and Exercise. She has been a lecturer at WIT for 20 years and supervised several research students investigating aspects relating to: low carbohydrate diets and their effect on health and sports performance, relative energy deficiency in sport in male athletes and polyphenol supplementation in relation to recovery from exercise and reduction of inflammation. Dr. Doyle is interested in any type of research which affects the health of individuals and/or their performance in sport.

Dr. Doyle has investigated the effects of a low carbohydrate versus high carbohydrate diet on endurance athlete performance and health. Aspects measured in this research include time trial performance, power output, fuel utilization, bone density, lean body mass, bone formation and resorption, blood cholesterol and inflammatory markers. Dr. Doyle has also supervising research examining energy balance in athletes. in relation to relative energy deficiency in Sport (REDs). I addition Dr. Doyle has supervised the design of a functional food aimed to assist recovery from intense exercise. This was a high protein polyphenol based supplement examined in a sport nutrition context.
Dr. Doyle is external examiner for the MSc in Sport and Exercise Nutrition at Atlantic Technological University. Dr. Doyle is also external examiner for the BSc in Nutrition at St. Marys University, Twickenham. Dr. has been internal examiner for several PhD viva's. She is a member of the Nutrition Research Center at WIT. She is also a member of the Nutrition Society.
