The main focus of our laboratory is on the quantitative analysis of development. Our goal is to establish truly predictive and multiscale models that connect multiple levels of description, from gene sequence to pattern formation and morphogenesis. We emphasize close coupling between experiments, computations, and theory, and use Drosophila as an experimental system for model validation. Current projects include genome-wide experimental analysis of signal integration in the Drosophila ovary, computational prediction of sequence-specific patterns of gene regulation by multiple extracellular signals, parameter estimation for morphogen gradients, and quantitative analysis of feedback control in pattern formation.
