Patterns in Turing patterns: sequential growth and the inhibitory cascade

Certain repeating elements of the body, such as teeth, fingers, limbs and vertebrae, are shown to follow the rule that the size of the middle element of a group of three is the average size of the three elements [1]. This simple rule constrains how the relative sizes of structures develop in the embryo and evolve over long periods of time. The precise mechanisms that determine the number and size of repeating structures, such as fingers and teeth, remain largely unknown. This project will develop mathematical and computational models to investigate possible biological mechanisms of sequentially patterned growth. These models will be based on reaction–diffusion problems on growing domains [2, 3] and generalisations of Turing-like patterning mechanisms.
