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.

Recent News: 

Congratulations to Barbara Sumic, a summer intern in the group supported by the Royce Undergraduate Internship Scheme, for winning a poster prize on her work “Effect of electrode surface structure on structure of aqueous ZnSO4 electrolyte.”

Welcome to new postdocs Veronika Sedajova and Debashis Tripathy, who joined the group in April 2023.

Congratulations to James Ellison, who won the best abstract award at the 64th ENC (Experimental Nuclear Magnetic Resonance Conference) in Pacific Grove, California.
