Systems Medicine


Systems Medicine Overview


We investigate pathomechanisms of diseases to improve diagnostics and treatment protocols based on mathematical modeling. Especially, we are working on quantitative descriptions of cellular pathways involved in cancer to support the development of improved therapeutic strategies in oncology. Inspired by the motto “semper apertus” of our university, we are always open for exchange and collaborations with other research groups across disciplines to move towards a functional understanding in pathophysiology and translational medical research.


Mathematical modeling in medicine and cellular biology

The systems medicine team is dedicated to applications of mathematical modeling in medicine and cellular biology. Our aim is to understand functional aspects of signal transduction systems in cells with focus on cancer research. To this end, we combine different types of mathematical models with biological experiments or clinical data. To calibrate models, we apply experimental methods for protein quantification, microscopy as well as sequencing techniques. In particular, we perform live-cell imaging to quantify processes in single cells and capture heterogeneity in cell populations. Recently, we developed a microscopy platform for automated live-cell imaging and perfusion with chemotherapeutic drugs called CytoScanner. Using this platform and algorithms from the field of machine learning, we want to optimize administration schedules of chemotherapeutic drugs.

Based on mathematical modeling, biomedical problems such as the initiation of apoptosis by pro-caspase-8 cis-/trans-cleavage, CRISPR/Cas9-mediated gene editing, or the early detection of atrial fibrillation were addressed.

Health Data Science

Furthermore, we are active on the field of data science in medicine. In this context, we work on developing predictive models for diagnostic applications and the early detection of diseases. Previosly, we established and clinically validated the ECHO-AF scores to predict the presence of paroxysmal atrial fibrillation (pAF) using non-invasive medical history and echocardiographic parameters (
