Research Interests:
  • Mathematical modelling of RTK crosstalk mechanisms in cancer.
  • Linking model-derived features to cell fate via machine learning
  • Establishing a gene network for developmental timing in early Zebrafish embrios through Pou/Sox transcription factors
  • Approximation of prediction and validation bands via integration methods with adapted correction mechanisms (Download of analytical ABC example)
  • Integration and optimisation techniques, sensitivity computation
  • Co-Developer of open-source
