EP 231: From polygenic scores to AI-driven medicine with Andrea Ganna of the Institute for Molecular Medicine Finland

March 19
36 mins

Episode Description

This week on The Genetics Podcast, Patrick is joined by Dr. Andrea Ganna, Associate Professor at the Institute for Molecular Medicine Finland (FIMM). They discuss the promise and limits of polygenic risk scores for disease prediction and clinical trials, how large-scale electronic health records and AI models could transform medical research and healthcare planning, what Finland’s national health data infrastructure enables for population-scale studies, and how genetics can be used to strengthen trial emulation in observational data.
