In 2019/20 I am teaching ES386 - Dynamics of Vibrating Systems (with Dr Peter Brommer) and PX914 - Predictive Modelling and Uncertainty Quantification in the HetSys CDT.
My office hours are Fridays 2-4pm during term in room D210.
- Multiple PhD projects available through the HetSys Centre for Doctoral Training for an October 2020 start:
- Atomistic modelling of fracture for irradiated materials with Lukasz Figiel
- Adaptive probabilistic meshless methods for evolutionary systems with Tim Sullivan
- Uncertainty in phase diagram simulations with interatomic potentials with Albert Bartok-Partay, Peter Brommer and Christoph Ortner
- Feb 2020 Article on quantum/classical modelling of dislocations in tungsten out in Phys. Rev. Materials
- Feb 2019 HetSys Centre for Doctoral Training launched at Warwick, with several fully funded PhD positions open, including one to work with me and Christoph Ortner on advanced boundary conditions for defect simulations
- Dec 2018 Article on machine learning a general-purpose interatomic potential for silicon published in Physical Review X
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.

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. I was a senior researcher within the project, which is led by the Fritz Haber Institute and involves a consortium of 11 organisations throughout Europe. This project supported postdoctoral reseaarcher Dr Berk Onat.
- I held a Royal Society Research Project Grant (April 2017-Mar 2018) Bridging from Quantum Mechanical to Continuum Mechanical Models of Fracture, which provided funding for local computational resources.
- ARCHER eCSE project 11-7 (Sept 2017 - Feb 2018) supported postdoc Dr Letif Mones to implement preconditioned geometry optimisers in the CASTEP and ONETEP codes. Co-investigators were Dr Nick Hine and Prof. Christoph Ortner (Warwick) and Prof. Matt Probert (York).
- SiO2 Fracture: Chemomechanics with a Machine-Learning Hybrid QM/MM Scheme - project allocated 126 million core hours in 2016 on the Mira machine at the Argonne Leadership Computer Facility under the US DoE's INCITE programme to investigate stress corrosion cracking in silica. Co-investigators were Anatole von Lilienfeld and Alessandro De Vita.
- Multiscale Atomistic Simulation of the Mechanical Behaviour of Nickel-based Superalloys. Project allocated 20 million core hours at the Cineca and Jülich supercomputer centres. Other project members were Federico Bianchini, Alessio Comisso and Alessandro De Vita (KCL).
- I’m one of the authors of the libAtoms/QUIP molecular dynamics framework, available from our public github repository, and licensed under the GNU GPLv2.
- matscipy, a Python software library for computational materials science developed with Lars Pastewka.
- f90wrap, a utility for wrapping Fortran 95 code to make it accessible from Python, including support for derived types.
- Other software is available from my GitHub page, including an enhanced version of the AtomEye atomistic visualisation software which can read Extended XYZ (.xyz) and NetCDF (.nc) files (Note: the extended XYZ format is now also supported directly by OVITO and ASE).
