My personal and professional experiences have led to an increased interest in non-pharmacologic interventions to improve health and chronic disease related outcomes.  My academic training, research experience and clinical practice have provided me with a strong background in nutrition and exercise science.  I have experience managing large projects and clinical research trials using non-pharmacologic interventions. During graduate school I coordinated two clinical trials. The first was my main dissertation project which tested the efficacy of increased water consumption as a weight loss strategy among older overweight and obese adults consuming a hypocaloric diet for 12 weeks, as compared to a hypocaloric diet alone. Following completion of my dissertation project, I was a study coordinator for a pilot nutrition and exercise intervention in college freshmen. During my postdoctoral fellowship at Georgetown/Lombardi Comprehensive Cancer Center in the Office of Minority Health and Health Disparities, I was involved in numerous exercise interventions, such as an intervention to improve dietary intake and exercise habits of breast cancer survivors.My professional experiences have led to an increased interest in non-pharmacologic interventions as a means to improve health and overall wellbeing.
