Summary

In this episode of The Genetics Podcast, host Patrick Short interviews Dr. Bin Yu, a distinguished professor at UC Berkeley, about her work on uncovering epistatic interactions in complex diseases using machine learning. The conversation begins with a critique of the dominance of linear models in genetics, highlighting the need for model checking and the limitations of p-values. Dr. Yu explains how random forests, particularly her iterative random forest approach, can detect gene-gene interactions beyond additive effects. She describes the application of this method to hypertrophic cardiomyopathy using UK Biobank data, where they identified stable gene interactions despite modest prediction accuracy. The discussion covers the importance of stability, the PCS (predictability, computability, stability) framework, and the integration of dry and wet lab experiments. Dr. Yu also shares personal insights from her early life during the Chinese Cultural Revolution and reflects on balancing AI-driven productivity with human reasoning. The episode concludes with advice on developing observational skills and the importance of interdisciplinary collaboration.
