Research Goal

My long-term goal is to disentangle the interplay between psychosocial, ecological, and physiological factors on metabolic functioning and energy intake/expenditure to identify and target individuals most in need of intervention.

Current Research

I am a staff scientist at the Obesity and Diabetes Clinical Research Section of the Phoenix Epidemiology and Clinical Research Branch at the National Institute of Diabetes and Digestion and Kidney Disease (NIDDK). Given that context and early experiences play a unique role in development and health, an individual’s ability to function in unpredictable and uncontrollable environments may help explain how current life stressors modify energy allocation and functioning of the metabolic system. As such, my clinical research at the NIDDK incorporates contextual and psychosocial factors in the examination of energy intake, energy expenditure, and metabolic functioning. I am PI on a study protocol that examines the impact of both caloric intake and macronutrient content on energy expenditure. Current projects include delineating the underlying metabolic and hormonal profiles of individuals with food insecurity, compared to food secure individuals. I am also involved in two systematic reviews and meta-analyses: (1) determines the impact of Respiratory Quotient on subsequent weight gain and (2) examines the relationship between perceptions of unpredictability on disordered eating.

Research in Plain Language

Obesity and its underlying cardiometabolic complications afflict approximately 20 million individuals residing in the United States. The quality of life, health care costs and loss of economic productivity add an unduly burden at the individual- and population-level. As such, the work in our unit seeks to understand the impact of psychosocial and physiological factors on food intake, energy expenditure, and weight gain. By understanding the interplay of these important factors, we ultimately hope to inform interventions that will target populations most at risk.
