The development of multicellular organisms is a spatially and temporally dynamic process. A single cell, the fertilized egg, divides many times to generate many functionally different cells, each of which is brought to a specific position to produce complex multicellular structures, i.e. organs and the body. An effective approach to such spatially and temporally dynamic processes is an approach that combines quantitative techniques with modeling and computer simulations. To understand the mechanism of organism development, we are developing mathematical models for developmental systems like the C. elegans embryo, mouse embryo and three-dimensional cell culture systems, by combining molecular cell biology and genome science with biophysics and computer science methods.
- System analysis of development by using large collections of quantitative dynamic information
- Mathematical modeling of development
- Development of technology for measuring developmental dynamics
