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 39 group members including 19 PhD students (8 students being co-supervised) and 20 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with more than 10 nationalities represented.
Congratulations to Dr Ieuan Seymour for his successful viva on the 20th of October!
Welcome to our new group members! This October, we welcome two new postdoctoral researchers: Erlendur Jónsson, who will work on the modelling/characterization of the SEI of Na-ion batteries, and Lauren Marbella, who will work on in-situ NMR and MRI of novel battery materials. We also welcome Anna Gunnarsdóttir who is starting a PhD with us after her summer internship in the group. Welcome as well to our part III students: Rajesh Jethwa, Can Kocer, Francesca Firth, Samantha Flint, Didi Rinkel and Rona McKee.
Congratulations to Dr Alison Michan for her successful viva on the 27th of September!
Congratulations to Dr Raphaële Clément for her successful viva on the 25th of July!
