The medical data science group carries out research at the intersection of machine learning and medicine with the ultimate goal of improving diagnosis and treatment outcome to the benefit of the care and wellbeing of patients. As medical and health data is heterogenous and multimodal, our research deals with the advancement of machine learning models and methodologies to address the specific challenges of the medical domain. Specifically, we work in the areas of multimodal data integration, structure detection, and trustworthy (or transparent) models. The challenge lies not only in developing fast, robust and reliable systems but also in systems that are easy to interpret and usable in clinical practice.
