Computer-Accelerated Design of Materials

We are a research group at Imperial College London working at the intersection of quantum chemistry, machine learning, and materials science. We use high-performance computing to design and optimise materials from first principles to function. Our work spans atomistic simulations, data-driven modelling, and multi-scale theory. The group is led by Professor Aron Walsh and is part of the Thomas Young Centre and the Centre for Processable Electronics.

Open Positions

• For postdoctoral candidates, the next call for Newton International Fellowships will be in early 2026.

• For PhD candidates, the best time to get in touch with your CV and motivation is in October-December for admission in the following academic year.
