Episode Description
Summary
Ben Lengerich discusses the importance of context in AI for healthcare, the role of generalised additive models (GAMs), and the challenges of data quality and data compliance. He emphasises the need for responsible AI practices and highlights the impact of historical data on current medical practices. The discussion also touches on the future of personalised medicine and the necessity of investing in AI to improve healthcare outcomes.
Ben Lengerich is an assistant professor of Statistics at the University of Wisconsin–Madison and the founder of Intelligible, where he develops context-adaptive, interpretable AI methods to turn real‑world clinical data into reliable evidence for precision medicine. His research sits at the intersection of machine learning, computational genomics, and medical informatics, with a focus on models that are transparent to clinicians and that account for the specific health context of each patient. Before joining UW–Madison, he was a postdoctoral associate and Alana Fellow at MIT CSAIL and the Broad Institute, advised by Manolis Kellis, after earning his PhD in Computer Science and an MS in Machine Learning from Carnegie Mellon University, where he worked with Eric Xing on methods to uncover patterns in complex biomedical data.
