Digestive system diseases


To unraveling the causes and underlying mechanism of complex diseases, and to appraise and implement personalized prediction and therapy in practice.


The unit’s vision is to implement personalized medicine in routine clinical practice. We focus on understanding and predicting the (causal) factors associated with the clinical course and outcome of complex diseases of the digestive system, psychosis, cancer, and radiotoxicity (Figure). To this end, and to pinpoint patient-centered therapies, this unit conducts international population-based cohort studies, patient-based clinical studies, and randomized clinical trials. The unit collaborates with international cohorts and has co-leaders in several international consortia.
