Andreas’ research focuses on how observational data can be used to create evidence for personalized medicine. Currently, he is working on developing prediction models for patients undergoing surgery for colorectal cancer, with an aim to guide patients and clinicians better. Besides risk stratification, he is working on identifying drugs that might be repurposed for modifying surgical stress. Previous work has included biomarkers for surgical stress and poor oncological outcomes following surgery.
