Biological processes occur over a wide range of time and length scales and rely on the coordination of the different parts. In particular, the properties of a tissue depend on the interplay of its constituent cells, and the correct behaviour of the cells relies on coordinated interactions of subcellular processes. How these different scales interact is the main interest of my research.
In my previous research, I have focused on the role of intercellular interactions during Drosophila morphogenesis and three-dimensional cellular aggregation.My results provide insight into the mechanisms that affect tissue coherence, a topic of medical relevance since disruptions of these mechanisms are associated with a large number of diseases. Currently, I am involved in different projects that address the role of spatial interactions in the response of cells to drugs as well as in mouse embryogenesis.
All my projects are based on close collaborations with experimentalists. Together we use a systems biology approach. The joint work comprises planning of the experiments, bioimage informatics and mathematical modelling. As a mathematician, my contributions to the work flow are advice regarding the experiments and active involvement in the theoretical parts.
