Examining Social, Cultural and Economic Factors as They Relate to Health
Our lab focuses on examining social, cultural and economic factors as they relate to health. Our current research program focuses on creating and validating neighborhood indicators constructed from nontraditional Big Data sources, such as social media data and Google Street View images. Most recently, we have started building a chatbot for racial/ethnic minority mothers to deliver personalized and automated health information during the first year of life to address disparities in maternal and infant outcomes. We have been funded by the National Library of Medicine and National Institute on Minority Health and Health Disparities (K01ES025433; R01LM012849; R01MD016037).
