Griffin Weber is co-faculty lead of Biomedical Informatics at Harvard Catalyst. He is an associate professor of medicine at Beth Israel Deaconess Medical Center (BIDMC), a faculty member in the Department of Biomedical Informatics (DBMI) in the Blavatnik Institute at Harvard Medical School, and an elected fellow of the American College of Medical Informatics (FACMI). His research involves developing methods for analyzing electronic health record (EHR) and medical claims databases, including characterizing the completeness of the data, identifying biases, matching patient records across federated data networks, and building scalable software tools to query data on millions of patients. He helped create several widely used open source, ontology-based, software platforms including Informatics for Integrating Biology and the Bedside (i2b2), which enables investigators to analyze large clinical databases, and the Shared Health Research Information Network (SHRINE), a federated query tool for distributed clinical data networks. Weber is additionally the creator of Harvard Catalyst Profiles, an open source social networking website for scientists, used at dozens of universities across the country.
