Description of the project The purpose of this project is to develop a quantitative theory of stochastic homogenization. Primary applications concern the analysis and computations for random models in physics and materials science, such as numerical methods for diffusion in heterogeneous media and the mathematical derivation of nonlinear elasticity theory from polymer-chain networks models. The mathematical fields of concern are:
The first part is devoted to the development of a quantitative theory of stochastic homogenization. The far-reaching goal is to quantitatively relate the statistics of the solution of a PDE with random coefficients to the statistics of its coefficients for the largest class of PDEs and coefficients possible. The prototypical equation considered is a linear elliptic equation in divergence form. The second part is devoted to the development and the analysis of numerical methods to solve PDEs with rapidly oscillating coefficients, which are consistent and optimal with respect to the quantitative stochastic homogenization theory. The third part is devoted to the mathematical derivation of nonlinear elasticity theory from polymer-chain networks models. The aim is threefold:

Post-doctoral positions: there are 4 post-doc positions available (each of two years). Post-doctoral subjects include (but are not limited to) the projects above. Questions such as effective behavior of random models (quenched CLT for Markov processes, effective laws etc.) can be considered depending on the background of the candidate. If interested send me an e-mail. Collaborators in mathematics:
