Research Fellow in Computational Chemistry

The aim of this project is to develop and apply the Sequential Monte Carlo (SMC) method in the context of biomolecular simulations. There is a long-standing interest in molecular simulation to develop enhanced sampling algorithms to address the known limitations of conventional molecular dynamics. SMC has been used in a number of fields, but has received little attention in biomolecular simulation. In this project, you will develop and apply the molecular-SMC approach to two main classes of problem in biomolecular modelling – to protein-ligand docking, and to binding free energy calculations.

PhD Studentship - Getting more from low-resolution methods: the combination of SAXS and atomistic molecular simulation

Small angle X-ray scattering (SAXS) provides structural information in the solution phase at room temperature, but is limited in terms of resolution. In this multidisciplinary project, you will work in close collaboration with scientists at the Diamond Light Source (DLS) to develop theoretical methods and software to combine atomistic molecular simulations with SAXS data, to extend the structural information from SAXS experiments to higher resolutions.
