Research interest

Networks allow representing interactions between entities and are highly informative. They enable the combined analysis of different data views. We are interested in combining network-based data analysis approaches with machine learning and mathematical modeling of dynamic processes. Applications stem mainly from a biomedical background, such as drug response prediction, and we focus on integrating different kinds of data with biomolecular, "multi-omics" data.

Selected projects:

  • Multi-omics network-based prediction of differential drug response (DrDimont)
  • Drug response prediction using graph-neural networks
  • COVID19 forecasting with mobility data by graph-neural networks and differential equation models
  • Autoencoder-based prediction of phenotype-specific drug targets from perturbation data
  • Proteogenomic abundance imputation
  • Graph-neural networks to leverage peptide- and transcript information
