About

I am Christopher Woods, a postdoctoral researcher at the Centre for Computational Chemistry, University of Bristol, currently funded by the EPSRC.

I have developed two major pieces of molecular simulation software; Sire, and ProtoMS. I use these programs to develop new methods to enhance the accuracy and precision of biomolecular simulations. I am currently developing new methods that allow for rapid Monte Carlo sampling of biomolecular systems modelled using multiscale quantum mechanics / molecular mechanics (QM/MM) and coarse grain (CG) / MM / QM Hamiltonians, and am applying this methodology to the calculation of relative protein/ligand binding free energies, and to investigate the free energy profiles of enzyme-catalysed reactions. I am also working on improved methods of sampling protein conformational change during free energy simulations, and am developing a new method that uses the flexibility of Sire to calculate absolute binding free energies using the Gibbs Ensemble. Prior to this, I developed the RETI free energy method, which uses replica exchange moves to enhance sampling and reduce random error in relative free energy calculations.

I have over ten years experience writing scientific software, and am an experienced Fortran, C++, Perl and Python programmer, and write parallel performance software using SSE, OpenMP, MPI and am currently playing with Intel's threaded building blocks, and Apple's libdispatch.
