For nearly forty years, Stanford’s Division of Biomedical Informatics Research (BMIR) has quietly shaped the way medicine understands data. Its faculty have built the frameworks that let clinicians ask sharper questions, the algorithms that make sense of millions of medical records, and the systems that help translate discovery into practice. But as their work has expanded — from building databases to designing AI models that guide clinical care, the name Biomedical Informatics Research no longer feels large enough to hold it.

That evolution has now been captured in a new name: Computational Medicine, with a mission embodied in its tagline: Constructing the Future of Health with Data-Driven Tools.

We’re proud to share that Mark A. Musen, MD, PhD, FACMI has been elected as a Distinguished Fellow of the American College of Medical Informatics (ACMI) in the 2025 class of Fellows. The ACMI Distinguished Fellow designation is one of the highest honors in biomedical and health informatics, recognizing individuals whose sustained leadership and scholarly contributions have significantly advanced the field. Dr. Musen has been formally inducted alongside his colleagues at the 2025 AMIA Annual Symposium in November.

When a patient shows signs of sepsis, minutes matter. But treating every case the same can lead to overtreatment or deadly delays. Division faculty Purvesh Khatri, PhD, and his team have developed a rapid blood test that helps clinicians make faster, more precise calls.
