PhD theses
- Topic: Advanced numerical methods for molecular dynamics
Description: The aim of this thesis, funded by the ERC project EMC2, will be to develop variance reduction methods in computational statistics, with applications to physical systems in molecular biology and materials science. The precise topics will be made precise in the coming months, but will in any case involve the analysis and efficient simulation of high dimensional stochastic differential equations such as the Langevin dynamics, for issues related to sampling of rare events or nonequilibrium systems.

- Topic: Quasistationary distributions for parallel accelerated dynamics
Description: The aim of the postdoc will be to develop new approaches to parallel algorithms employed in molecular dynamics to accelerate the simulation of trajectories of metastable stochastic processes. It will be based on theoretical notions from the theory of stochastic processes, such as quasistationary distributions and semigroup intertwinning.

- Topic: Parareal algorithms for molecular dynamics
Description: The parareal algorithm, originally proposed in 2001, is a very efficient algorithm to solve initial-value problems (e.g. ODEs or SDEs) using parallel-in-time computations. The algorithm is based on a decomposition of the time interval into subintervals and exploits the presence of multiple processors to reduce the wall-clock time needed to obtain a solution on some time interval. The aim of the postdoc will be to develop new variants of the algorithm, better suited to the molecular dynamics context (where SDEs are considered on very long time horizons), and to test them on simple problems.
