Single-cell RNA sequencing is transforming our understanding of tumor heterogeneity in primary lung cancers by offering insights far beyond traditional bulk sequencing. In this program, Dr. Paola Marignani explores how advanced machine learning enables faster, more precise profiling of genetic diversity, predictive modeling for recurrence and drug resistance, and personalized treatment strategies. Dr. Marignani is a Professor in the Department of Biochemistry and Molecular Biology at Dalhousie University in Halifax, Novia Scotia, and she spoke about this topic at the 2025 World Conference on Lung Cancer.
