Research interests

I develop and apply mathematical models to study complex biological systems. Techniques range from discrete and continuous models of temporal dynamics to more computationally intensive individual-based and multiscale simulations. Major applications include mechanisms underlying tissue homeostasis and their disruption in cancer formation and progression, and the orchestration of cell-level processes such as proliferation, death, adhesion and migration to give correct tissue-level proportions in embryos.
