The objective will be to participate in : - formulating a 3D continuum mechanics model for the cardiac muscle contraction due to the electrical actuation; - developing appropriate numerical (finite element) procedures for the model; - performing validations by comparing the results with experimental data (collaborations with clinical teams). This post-doc will be part of the INRIA collaborative research project ICEMA-2 ("Images of the Cardiac Electro-Mechanical Activity"): http://www-rocq.inria.fr/sosso/icema2/icema2.html This position is open for an initial duration of 12 months. Requirements : - Applicants should hold a PhD in numerical analysis or mechanical engineering; - Prior extensive experience with non-linear continuum/structural mechanics and finite element development is essential. In addition, we strongly encourage applications of young researchers (less than about 30). Send CV, statement of interests, 2 most prominent publications, and one (at least) letter of recommendation to: D.

The project is concerned with the analysis and development of algorithms for the extraction of simple stochastic models for components of large and complex deterministic dynamical systems. The project involves both theoretical and computational work, and the balance between the two can be determined by the interests and strengths of the succesful applicant. Both simple model problems, and more involved applications, will be studied. Applications include a range of problems in molecular dynamics of materials. Knowledge of any one (or more) of the following will be advantageous: stochastic processes, dynamical systems, computational PDE, Markov chains and hidden Markov models.
