Dr. Ozonoff's research focuses on the development and application of methods for surveillance of health and disease. This includes public health surveillance, especially infectious disease surveillance, as well as hospital-based surveillance, with emphasis on patient safety and healthcare quality. He leverages his training in mathematics, statistics, epidemiology, and data science to achieve population-based improvement in the health of children and adults.
Research Background
Dr. Ozonoff is Associate Professor of Pediatrics at Harvard Medical School, faculty scientist at Boston Children's Hospital, and Adjunct Associate Professor of Biostatistics at the Boston University School of Public Health. His scientific research is focused on development and application of surveillance methods in the fields of public health, healthcare quality, and patient safety. He is Principal Investigator of a 5-year project funded by the Agency for Healthcare Research and Quality (AHRQ), "Patient safety surveillance using machine learning and free text clinical notes" (R01 HS026246-01A1) and leads the Data Management Core for the Precision Vaccines Program at BCH. He holds advisory and consulting roles with state agencies including the Massachusetts Cancer Registry, the Massachusetts Office of Population Health, and the Massachusetts Bureau of Environmental Health.
