Research summary

Our research focuses on image-based mathematical modelling of multicellular systems in biomedical research. The main interest is how cells interact in a tissue, in particular the influence of the local cell neighbourhood on the behaviour of a given cell. We have previously developed discrete reaction-diffusion models to investigate the role of intercellular interactions during Drosophila morphogenesis and a three-dimensional agent-based model to investigate cellular aggregation. A major emphasis is on developing data-informed models. To obtain the necessary data, we have established a multiscale image analysis pipeline for three-dimensional fluorescence microscopy images and implemented three-dimensional cell graphs for studying the cell neighbourhood. Currently, we work on studying cell fate specifications in early mouse embryos.
