Pattern formation of biological structures involves the arrangement of different types of cells in an ordered spatial configuration. Patterning is thought to involve the spatial organization of molecular pre-patterns that precede and drive subsequent cell differentiation and coinciding morphogenesis. These molecular prepatterns are often, although not exclusively, organized through Turing...
Cells are often precisely organized into patterns within developing tissues. This precision must emerge from biochemical processes within, and between cells, that are inherently stochastic. I investigated the impact of stochastic gene expression on self-organized pattern formation, focusing on Senseless (Sens), a key target of Wnt and Notch signaling during...
Organismal development depends upon countless cell decisions to adopt particular fates at the appropriate time and place. These decisions are executed by systems of biochemical reactions called regulatory networks. Elucidating the general principles underlying the structure and function of these networks is vital to understanding all developmental processes, as well...
