Tolkach Lab is a computational pathology/oncology research group at the University Hospital Cologne (www.tolklab.de). We are located in the Institute of Pathology and tightly associated with different other departments and research groups on the campus of the University. The main research directions of the lab are AI-based diagnostic, prognostic, and predictive tools for pathology and oncology, multi-modal data integration, and studies of intratumoral heterogeneity and cancer evolution.
