Dr. Jonathan M. Green, M.D., MBA, has been named chief executive officer of the National Institutes of Health Clinical Center, the world’s largest hospital devoted exclusively to clinical research. He will assume the role on May 17, 2026.
According to NIH Director Jay Bhattacharya, M.D., Ph.D., Dr. Green’s expertise in enhancing NIH’s human research protection program, along with his background in pulmonary and critical care, positions him to lead the Clinical Center in advancing patient care and biomedical discovery through clinical trials.
As CEO, Dr. Green will oversee the Clinical Center’s nearly $700 million annual operating budget and manage operations of its 200-bed, 870,000-square-foot research hospital on NIH’s Bethesda campus. The center reported over 3,000 inpatient admissions and nearly 72,000 outpatient visits last year. All patients participate in research protocols.
The Clinical Center is undergoing a major expansion expected to add more than 570,000 square feet, modernizing facilities to support top-tier patient care and research. Construction is projected to finish by 2029.
Dr. Green joined NIH in 2018 as director of the NIH Office of Human Subjects Research Protections, leading a consolidation of 12 separate NIH Institutional Review Boards into a centralized board serving the intramural research program. Institutional Review Boards evaluate research involving human participants for ethical and regulatory compliance; approval is required for research to begin.
Before joining NIH, Dr. Green was a professor of medicine, pathology, and immunology at Washington University School of Medicine in St. Louis and served as Associate Dean for Human Studies and Executive Chair of the IRB. His research focused on molecular mechanisms of T cell activation, particularly the CD28 costimulatory receptor family.
