Co-Chair, Center for Integrated Healthcare Data Research, is a Professor of Neurology at Harvard Medical School and Director of Partners HealthCare Research Information Systems. Dr. Murphy developed the Research Patient Data Registry (RPDR) for Mass General Brigham, which serves over 5,000 investigators performing research using the hospital medical record. This application served as the test bed in developing the open-source Informatics for Integrating Biology and the Bedside (i2b2) software platform now operating at over 120 hospitals worldwide. He was Co-PI of the Accessible Research Commons for Health (ARCH), a clinical data research network of the Patient-Centered Clinical Research Network (PCORnet). He is the Co-chair of the Center for Integrated Healthcare Data Research and oversees the integration of the long-term outcome data sources into the Mass General Brigham research query tools via the “Big Data Commons” data integration strategy.

Joshua K. Lin, MD, ScD, MPH

Executive Director, Center for Integrated Healthcare Data Research, is a practicing general internist, a pharmacoepidemiologist in the Division of Pharmacoepidemiology and Pharmacoeconomics at Brigham and Women’s Hospital (BWH), and an Assistant Professor in Medicine at Harvard Medical School. He is the PI of multiple NIH-funded large-scale studies aiming to improve validity of comparative effectiveness research (CER) using EHR linked with insurance claims data. He led an initiative to link the Medicare and Medicaid insurance claims data with electronic health records (EHR) of the Accessible Research Commons for Health (ARCH), a clinical data research network of the Patient-Centered Clinical Research Network (PCORnet). He has published extensively about drug safety and effectiveness using EHR and claims data in vulnerable populations in high impact medical journals. His pioneer work has resulted in validated algorithms substantially reducing the information bias due to care received outside of study provider system, a pervasive bias in the US EHR system. As the Executive Director of the Center for Integrated Healthcare Data Research, Dr. Lin will lead a team of research scientists and administrators to manage the day-to-day operations of the Center, including writing and executing data use agreements, requesting data and conducting linkage, developing and executing data curating measures, and reviewing Mass General Brigham research requests for usage of the linked LTO data assets.
