Our research vision is to understand, and ultimately to design, amorphous materials on the atomic scale. We combine quantum mechanics with machine learning (ML) to study relationships of structure, bonding, and properties. Our work is theoretical and computational, but is done in close collaboration with experimental partners, and with practical applications in mind.

Machine-learned interatomic potentials for materials chemistry

Computer simulations based on the laws of quantum mechanics are a cornerstone of materials research – but they are severely limited by their computational cost. We develop and apply interatomic potential models that "learn" from quantum-mechanical data, enabling accurate simulations that are many orders of magnitude faster. A central theme in this part of the group's research is the role of training data in atomistic ML.

Structural chemistry of amorphous solids

Amorphous (non-crystalline) materials are a frontier of current materials research: their disordered structures are difficult to determine experimentally, and they also pose large challenges for computational modelling. We use advanced computer simulations to explore amorphous structures on the atomic scale. In this part of the group's research, we are purely driven by curiosity – we aim to create the most realistic models of amorphous structures, and we aim to understand the subtle rules that guide their formation.

Functional materials by design

We study the connections between microscopic structure and macroscopic functionality in inorganic solids. We are interested in functional materials for a variety of applications: phase-change materials for digital memories, battery anodes and solar-cell materials, and graphene oxide.
