Overview

  • Obesity is one of the most serious and complex public health challenges our society has faced. Past research has shown tremendous inter-individual variability in weight loss in response to physical activity and dietary interventions, which is driven by a complex set of biological, behavioral, environmental, and psychosocial influences on adherence and energy balance. My education and training in exercise nutrition, and translational science have fostered a strong desire to understand this complexity and contribute to the development and implementation of evidence-based and tailored strategies to reduce obesity.

    Research Overview

  • My past research has centered on the effects of the quantity and quality of dietary protein on energy balance, obesity, and cardiometabolic health. My predoctoral research was focused primarily on studying the role of dietary protein on appetite, energy balance, and neural reward responses to visual food stimuli. I also have experience with conducting randomized clinical trials to investigate the impact of dietary protein on cardiometabolic health and weight loss in adults with obesity and type 2 diabetes. My current research at UAB is focused on studying the factors that contribute to the variability in behavioral weight loss interventions and conducting adaptive clinical trials (e.g., Sequential Multiple Assignment Randomized Trials or SMARTs) to develop, rigorously evaluate, and implement effective interventions to treat obesity.
