In development, a single cell, the fertilized egg, turns into a complex organism consisting of millions of cells. The cells of the embryo differentiate into many different cell types, and they are arranged in complex spatial patterns. This process generally proceeds with striking precision. Our group is interested in understanding the mechanisms that ensure the stability of developmental processes despite stochastic perturbations. We use the zebrafish as a model system to study organ development and regeneration. Our projects typically combine experimental and theoretical approaches, and it is our goal to study single cells in their spatio-temporal context. To this end, we use and develop novel genome-wide single-cell approaches.
