My laboratory asks fundamental questions in bio-medical research. The focus of our research is morphogenesis, i.e. how cells are assembled into functional forms. We are concerned with the principles that determine the specific number, size and shape of different organs. This is an important process, as there is much to learn about the principles that can guide stem cells to form specific tissues and organs required for medical treatment. Our approach is to ask Nature how she does it - using the feather as a Rosetta stone to decipher these principles, because of the distinctive forms of feathers and interest in the evolution of flight. This unique model has allowed us to make several major impacts in the field of morphogenesis and develop interesting interfaces with scientists in different disciplines.
