I develop multiscale materials modelling algorithms and the software that implements them. My recent work applies this parameter-free modelling to make quantitative predictions of "chemomechanical" materials failure processes where stress and chemistry are tightly coupled, e.g. near the tip of a propagating crack (left), where local bond-breaking chemistry is driven by long-range stress fields. Recents projects include:
In 2020/21 I am teaching ES386 - Dynamics of Vibrating Systems (with Dr Peter Brommer) and PX914 - Predictive Modelling and Uncertainty Quantification in the HetSys CDT.

Previous Research Projects
- Hydrogen Embrittlement of Steels - I was an external associate of this EPSRC Programme Grant involving Oxford, Cambridge, Imperial, King's and Sheffield.
- My EPSRC First Grant Predictive Modelling of the Fundamentals of Failure in Metals (Aug 2016 - July 2018) had the overarching aim of developing new models to enable continuum-scale modelling of failure processes, in particular crack growth, by incorporating pre-computed first-principles information. This funding supported postdoctoral researcher Dr Petr Grigorev.
- The Novel Materials Discovery (NoMaD) laboratory, funded under the Horizon 2020 Centre of Excellence initiative, enables access to the huge amount of data routinely produced by computational materials science calculations through the online NoMaD repository.

This project supported postdoctoral reseaarcher Dr Berk Onat.
