Rosemary Hamsley is a graduate research assistant in the Healthy Eating and Activity Laboratory. She received her master’s in exercise science from Tennessee Technological University. Throughout her studies and work experience, she has been amazed at the impact that physical activity and proper nutrition could have on the body. Rosemary decided to pivot slightly from exercise and continue her studies in nutrition science as a PhD student. Her research interests include how life experiences influence eating behaviors and how interventions can be designed with this idea as a guide.
