Research position advertised

Come and work with me on antimicrobial resistance! Advert here. Broadly the idea is to develop our work using machine learning and molecular simulation to predict whether individual bacterial protein mutations confer resistance to an antibiotic (or not). Any questions please get in touch. For more details please see the advert, especially the lists of […]

New publication: how quickly can be calculate the effect of a mutation on an antibiotic?

The idea for this paper arose during talking over coffee at the BioExcel Alchemical Free Energy workshop in May 2019. We’d previously shown that alchemical free energy methods could successfully predict which mutations in S. aureus DHFR  confer resistance to trimethoprim (and crucially, which do not). That is all well and good, but to do […]

AMyGDA now available from GitHub

AMyGDA is a python module that analyses photographs of 96-well plates and, by examining each well for bacterial growth, is able to read a series of minimum inhibitory concentrations for the antibiotics present on a plate. Previously it was only available to download from this website (due to licensing) if you gave your email address […]

New preprint: rapid prediction of AMR by free energy methods

The story behind this preprint goes back to the workshop on free energy methods run by BioExcel in Göttingen in May 2019. I gave a talk, based in part on the work I’d previously published showing how alchemical free energy methods are able to predict which mutations in S. aureus DHFR confer resistance to trimethoprim.

GROMACS2018 on NVIDIA DGX-1s

HECBioSim advertised for proposals to use JADE, the new Tier-2 UK GPU high performance computer back in April 2019. JADE is built around NVIDIA DGX-1s, each of which contains 8 Tesla V100 GPUs. I’d previously run some alchemical free energy calculations on ARCHER, the Tier-1 UK academic supercomputer that has a conventional architecture, thanks to […]

New publication: Predicting resistance is (not) futile

Our “First Reactions” article has been published in ACS Central Science. We discuss the paper, Predicting Kinase Inhibitor Resistance: Physics-Based and Data-Driven Approaches, by Matteo Aldeghi, Vytautas Gapsys and Bert de Groot, which is in the same issue of the journal. Aldeghi et al. apply a series of methods to try and predict the effect […]
