Can AI Accelerate Science? Dr. Andy Beam on AI’s Next Frontier
Dr. Andy Beam has trained models, mentored scientists, and used data to quantify the value of treatments. In this episode of NEJM AI Grand Rounds, Raj Manrai turns the table on his co-host, reflecting on how Andy’s childhood misdiagnosis, and the failure of human recall, revealed the diagnostic promise of machine learning. As a Harvard professor, he mentored hybrid thinkers and built tools to evaluate safety, not just performance. Now CTO of Lila Sciences, he’s building an experimental AI system to generate its own hypotheses and test them in the real world. This conversation is a front-row seat to the next evolution of science.

Google’s Efforts to Build Patient-Facing AI: A Conversation with Drs. Alan Karthikesalingam and Anil Palepu
In this episode of NEJM AI Grand Rounds, guests Drs. Alan Karthikesalingam and Anil Palepu of Google walk co-hosts Raj Manrai and Andy Beam through the making and evaluation of AMIE, an AI system designed to conduct clinical conversations with patients. Alan and Anil explain how AMIE was trained using synthetic doctor-patient interactions generated by LLMs playing multiple roles—doctor, patient, critic, and moderator. They reveal how synthetic dialogue, guided by structured feedback and grounded in search, proved more effective than noisy real-world transcripts in building a model that could reason, ask questions, and show empathy. The discussion also covers what the “long tail” of medicine demands for building robust AI systems and how AMIE might one day augment real clinical workflows. Finally, Alan reflects on how AI has changed—and how it hasn’t—in the two years since he was last on the podcast.

Rewriting the Clinical Playbook: Dr. Shiv Rao on Scaling Empathy with AI
Dr. Shiv Rao, cardiologist and CEO of Abridge, joins hosts Raj Manrai and Andy Beam on NEJM AI Grand Rounds for an inspiring conversation at the intersection of medicine, technology, and meaning. Shiv shares the origin story of Abridge, reflecting on how a deeply human encounter in clinic sparked the idea for a company now transforming clinical documentation across more than 100 health systems. From his early days programming electronic music to navigating LLM deployment at scale, Shiv offers a rare look into the soul of a founder building not just infrastructure — but a movement. He unpacks how generative AI can be used to restore presence in the clinic, what it takes to earn clinician trust, and why he believes taste, empathy, and curiosity are the real moats in health care AI.

Pixels to Protocols: Building the AI Future of Pathology with Dr. Faisal Mahmood
Dr. Faisal Mahmood, Associate Professor of Pathology at Brigham and Women’s Hospital and Harvard Medical School, joins hosts Raj Manrai and Andy Beam on NEJM AI Grand Rounds to explore the frontier of computational pathology. From pioneering foundational models for whole slide imaging to commercializing a multimodal generative AI copilot for pathology, Faisal shares how his team is redefining what’s possible in digital diagnostics. He discusses the power of open-source culture in accelerating innovation, his lab’s FDA breakthrough designation, and how generative AI could trigger widespread digitization in pathology. Faisal also reflects on his creative approach to problem selection and offers a vision for a future shaped by patient-level foundation models and agent-led computational biology.
