English developmental biologist and researcher. His work focused on cellular timing mechanisms and their role in animal development. He discovered the role of the Notch ligand in controlling nerve cell differentiation and synchronized cycling of neighboring cell activity. Additionally, he modeled the cellular oscillatory circuit that determines body segmentation during development.
