Hadi Kharrazi MD, PhD


Dr. Kharrazi is the co-director of the Johns Hopkins Center for Population Health IT (CPHIT). He is also an Associate Professor of health policy and management at the Johns Hopkins School of Public Health, with a joint appointment at the Johns Hopkins School of Medicine. His research focuses on population health IT solutions that provide direct population‐based decision support to providers, payers, and patients. His expertise includes assessing the needs and impact of health IT on care delivery, designing interoperable platforms for population health, and developing and evaluating advanced predictive models for risk stratification
Dr. Kharrazi has served as the PI of several federal grants and contracts (e.g., ONC, AHRQ, CMS, VHA) with a special focus on population health informatics. Within the context of population health IT, his research focuses on the application of informatics solutions to advance the science of population health analytics such as: evaluating the added-value of new sources of data (e.g., EHRs, social determinants of health) in population health analytics; assessing challenges of data quality on population health studies; and, utilizing health information exchange infrastructure to develop population health analytic platforms. He also serves on the editorial boards of JAMIA Open and Population Health Management journals.

Dr. Kharrazi has an extensive record on education. He has been the Co-PI of a DHHS-ONC award to develop a national curriculum for population health informatics, and train more than 9000 healthcare professionals nationally. He is also the director of the DrPH Informatics track at the School of Public Health, and the director of Health Sciences Informatics PhD and MSc Research programs at the School of Medicine.

Peter S. Greene, MD
