Justin Rousseau, M.D.

Justin Rousseau, MD, MMSc, is an Associate Professor in the Department of Neurology and the Peter O’Donnell Jr. Brain Institute at UT Southwestern. He is a member of the Clinical Informatics Center, serves as Deputy Chief Medical Informatics Officer for Neurosciences, and is a member of the Informatics Core of the UT Southwestern Clinical Translational Science Award (CTSA) Program. He is board certified in neurology and clinical informatics. Built on foundational education in systems engineering, Dr. Rousseau obtained his medical degree from the University of Oklahoma Health Sciences Center. He completed his neurology residency at UC San Diego, where he was chief resident. He then completed a NIH National Library of Medicine fellowship and Master of Medical Sciences in Biomedical Informatics at Harvard Medical School and Brigham and Women’s Hospital with the Center for Evidence-based Imaging. He joined UT Southwestern in 2023 after seven years with the Departments of Population Health and Neurology at Dell Medical School at UT Austin.

Dr. Rousseau seeks to advance brain health research and care through secondary use of electronic health record (EHR) data. His research and development interests to achieve this include developing and applying biomedical informatics methods including natural language processing (NLP), information extraction, standard ontologies and terminologies, computable phenotyping, and data warehousing to identify, harvest, and make accessible pertinent biomedical and health care data to support evidence-based clinical decisions, information sharing through transitions of care, and health research.

Dr. Rousseau leads clinical research informatics efforts to collect, manage, analyze and warehouse health data to support development of learning health systems and clinical research networks. Example projects include: (1) Early Psychosis Intervention Network of Texas (EPINET-TX); (2) Texas Childhood Trauma Research Network (TX-CTRN), and (3) Immunophenotyping Assessment in a COVID-19 Cohort (IMPACC) study. During his time at Dell Medical School at UT Austin, Dr. Rousseau co-founded and co-directed the Data Core, which was adopted as part of Dell Medical School Enterprise Data Intelligence, a central resource for investigators accessing, managing, and analyzing clinical and non-clinical health-related data serving research and quality improvement activities through development of computable phenotypes to define patient cohorts, extraction of clinical data, and integration with other sources of data.
