Our Fellows

Andrea Krenek
Andrea Krenek, RDN, LDN
Registered Dietitian and Doctoral Fellow

Andrea Krenek is a registered dietitian and NIDDK predoctoral fellow in the Chung Group lab. Prior to pursuing a doctoral degree in Nutritional Sciences at University of Florida, Andrea Krenek received her Bachelor of Science in Nutrition and Bachelor of Science in Kinesiology degrees at Texas A&M University. To support her interests in integrating dietetics, clinical research, and culinary nutrition, Andrea completed her professional culinary training through Rouxbe Cooking School, followed by her dietetic internship through The Ohio State University. Her doctoral research focused on the effects of dietary and culinary nutrition interventions on cardiometabolic, psychological, and dietary outcomes. She hopes to expand these approaches to a range of populations and health conditions, addressing disparities in youth and young adults, and investigate underlying metabolic and behavioral mechanisms. Outside of the lab and kitchen, she loves all kinds of exercise, outdoor activities, food photography, music, podcasts, and exploring new places.
