As the CHIO, Dr. Hsiao leads the medical informatics and data and analytics teams for the School and System, including an experienced group of physician informaticians and the Joint Data and Analytics Team. He and team provide leadership of the EHR and technology to provide the functionality, clinical decision support, and innovation needed to deliver the best healthcare possible. His Joint Data and Analytics Team includes the database administrators, data architects, and a team of over 60 analysts that provide the reporting and analytics for the System and the School, supporting operational, clinical, and research reporting and data needs and is led by a talented Chief Data & Analytics Officer.
