My research interest focuses on reducing health disparities in social and environmental determinants of health among vulnerable populations using a mixed methodology. Specifically, my research focuses on examining how individual socioeconomic status, psycho-social factors, behavioral, neighborhood environmental factors, and access to health services influence the physical and mental health in underserved populations and communities (e.g., maternal women, children, racial/ethnic minorities). In addition, I am also interested in developing innovative health behavioral interventions (e.g., smoking cessation) using smart phone and ecological momentary assessment (EMA) method.
