In this episode of PRIM&R's podcast, "Research Ethics Reimagined," we explore the philosophical foundations of research ethics and the challenges of deploying artificial intelligence in medicine with Alex John London, K&L Gates Professor of Ethics and Computational Technologies at Carnegie Mellon University, where he directs the Center for Ethics and Policy. Professor London discusses his book “For the Common Good,” which argues that justice should be the foundational principle of research ethics. Professor London also offers his assessment of AI's promise and limitations in healthcare.
