Research

Pierre is a member of the Biological Physics research group in the Department of Applied Mathematics and Theoretical Physics. His research is on the mathematics of morphogensis: how does shape arise in physical systems, living or otherwise?. In particular, Pierre is interested gaining a mechanical understanding of the inversion process in the green alga Volvox

Shape generating chemical systems are a very literal instantiation of Turing's quest for the chemical basis of morphogenesis. Pierre has been interested in developing a theory describing a recently discovered exemplar of such a system: oil emulsion droplets that flatten into a variety of polygonal shapes upon slow cooling.

Another research interest centres around probabilistic models for the prediction of RNA secondary structures, in particular extending models based on stochastic context-free grammars to include kinetic transcription effects.
