The Grey Group

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 3 Master students, 22 PhD students (11 students being co-supervised) and 21 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with almost 20 nationalities represented.
