Most recently: The Human Values Project has become a major focus. With over 1,000 clinicians enrolled from three continents, we are systematically studying how AI models make value-laden clinical decisions and how those decisions compare with those of human clinicians and patients. This work led to the RAISE symposium consensus statement proposing a "Values in the Model" (VIM) transparency framework for clinical AI, published in NEJM AI. Alongside this, we have introduced MedLog, a universal logging protocol for clinical AI—think syslog for medicine—now being piloted at four sites across three continents. I continue to work with the Coordinating Center of the Undiagnosed Disease Network where we are ramping up efficiency through the use of AI, including providing self-service solutions for patients. Also, the cases of several of the patients that we were not previously able to diagnose have yielded to new genomic insights, also powered by machine learning (e.g. splicing variants in compound heterozygous cases). I am also quite busy plowing through submissions to NEJM AI and discussing the more interesting ones with the rest of the editors. Finally, I am revisiting a project I undertook in the 1990's, how to diagnose kids from their growth patterns—but now with LLMs and far more pediatric data.
An international effort to understand whose values are embedded in clinical AI. Over 1,000 clinicians enrolled across three continents, 15 frontier AI models tested. Developed the Alignment Compliance Index and proposed the "Values in the Model" transparency framework. See hvp.global.
Continuing to build editorial processes and community around NEJM AI. Establishing new standards for publishing AI research in medicine with focus on rigorous evaluation and real-world clinical validation.
A universal logging protocol for clinical AI—syslog for medicine. Four real-world pilots running in Vietnam, Switzerland, San Diego, and New York.
Active pilotsInvestigating AI model performance across populations and time, and variations in human values and utilities.
OngoingApplying AI to improve diagnosis of rare diseases via the Undiagnosed Disease Network, including self-service solutions for patients.
OngoingResearchers and clinicians I'd love to work with
The Human Values Project is actively enrolling clinicians and patients worldwide to review brief clinical scenarios (~15–20 min) so we can compare human decisions with those of AI models.
Data scientists who understand healthcare data complexities and are passionate about advancing the healthcare at the frontlines.
Building global partnerships to understand AI in healthcare across different healthcare systems, regulatory environments, and cultural contexts.
Music fuels creativity and provides the backdrop (or relief from) thinking. Here's what's been on repeat during my research sessions lately.
Isaac "Zak" Kohane, MD, PhD is Professor and Chair of the Department of Biomedical Informatics at Harvard Medical School and Editor-in-Chief of NEJM AI. Over his 30+ year career, he has pioneered the application of artificial intelligence and computational methods to clinical medicine, from early work on temporal reasoning in medical expert systems to current research on large language models in healthcare. Trained as a pediatric endocrinologist with a doctorate in computer science, he has bridged the gap between computational innovation and clinical practice, shaping how healthcare settings can become living laboratories for translational research. His work spans patient data sovereignty, clinical decision support systems, and the ethical deployment of AI in medicine. He has authored over 500 publications and mentored dozens of researchers who have gone on to lead AI initiatives across academia and industry.
