Hybrid DFT/ML-MD methods
Extending the capability of ab initio material simulations

The design of more durable materials is key to reduce the carbon emissions of construction, transportation and energy production. To achieve this requires an understanding of mechanical strength and toughness at the level of jiggling atoms.

We design theoretical and numerical tools to discover the atomic mechanisms by which solid materials bend and break. As the range of possibilities is practically infinite, the challenge is to find the most influential, then characterize these accurately. A particular focus is designing autonomous methods that harness massively parallel computers to rapidly search configurational space. This requires the development of statistical uncertainty measures, coarse-grained modelling tools and data-efficient machine learning approaches.

A better idea of our research interests can be found in our publications and open source software.
