Prof. Henrik Jönsson
Sainsbury Laboratory Cambridge University
The focus of Henrik's research is to develop computational morphodynamics models at the cellular level describing multicellular tissues such as the shoot apical meristem. The models are developed in close collaboration with experimental groups and describe the dynamics of gene regulatory networks, hormone transport and signalling, cell growth and division, and mechanical properties. Integral for the research is the iterative evaluation of the models and their parameters to new experimental data, mainly in the form of live microscopy data.
This includes the development of models for gene regulation and intercellular signalling, where the experimentally known CLAVATA-WUSCHEL negative feedback provides the core of the network. He develops models and optimises and evaluates model parameters with large perturbation experiments, where the approach focuses on regions of parameters to describe the model network behavior.
