The Department of Epidemiology welcomes new Research Assistant Scientist Dr. Hui Hu. Dr. Hu received his PhD in Epidemiology at the University of Florida in 2016, and his research interests focus on health effects of environmental exposures, substance use, and racial disparities in health outcomes. He has been involved in several NIH-funded research projects, where he managed and analyzed multiple large datasets such as the Epidemiologic Catchment Area Study, Afghanistan National Urban Drug Use Study, SEER registries, NHANES data, and Florida Vital Statistics Birth Records. He was also a fellow of the Insight Health Data Science program, where he developed a web application with interactive maps to help people with disabilities in Massachusetts to find the best neighborhood to live using machine learning models, integrating data from different sources. We are pleased to have this epidemiologist on board, specializing in spatial analyses and health data science.
