The Grey group studies the nature of solid state materials by nuclear magnetic resonance (NMR), X-ray and Neutron scattering, electron microscopy and computational calculations. The materials we investigate have applications in supercapacitors, fuel cells, and batteries. 

Our current research projects are described here and a full list of publications is available here. We currently have 49 group members including 2 Master students, 2 Research scientists, 23 PhD students (9 students being co-supervised) and 22 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with more than 10 nationalities represented.

Recent News:

Welcome to Dr Chibueze Amanchukwu, who will be visiting us from Stanford. His work will involve the use of solid-state NMR techniques to study the influence of polymer coatings on lithium metal deposition.

Welcome to Dr David Hall who joins us as a Research Associate in July. He will combine a variety of synthetic and analytical techniques to study interfacial chemistry of energy storage systems. He will also be acting as a joint programme coordinator for battery degradation studies with the Faraday Institution.

Congratulations to Dr Michael Hope who successfully defended his PhD viva on 7th June 2019!

Congratulations to James Ellison for achieving the Ron Snaith Prize for his excellent part III presentation.

The annual Grey Group retreat was held in the Peak District between 8th-12th May 2019. Special thanks to Team Retreat: Dr Matthew Dunstan, Philip Reeves, Francesca Firth, and Yuning Zhou.

Welcome to Dr Dominik Kubicki who is an MSCA Fellow in the Stranks Lab (Cavendish Laboratory) who joined the group in April. He will use multi-nuclear solid-state NMR to study lead halide perovskites for optoelectronics.
