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 56 group members including 4 Master students, 26 PhD students (15 of whom are co-supervised by another PI) and 26 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with over 20 nationalities represented.

Recent News: 

Welcome to our new cohort of PhD and Masters students who started earlier this month.

Congratulations to Vera Kunz for passing her PhD viva!

Congratulations to Teresa Insinna for passing her PhD viva!

A large cohort from the group attended the Faraday Institution's 2024 conference in Newcastle. Congratulations to Dr Veronika Sedajova for winning a poster prize, and to PhD student Jessica McConnell for a commendation in the "Intercalation Station" essay prize.

Congratulations to Astrid Berge, PhD student, for winning a poster prize at the Rocky Mountain NMR conference!

Congratulations to Holly Smith for passing her PhD viva!

Congratulations to Dr. Sundeep Vema for winning the Young Surface Analyst Castle Prize at the UK Surface Analysis Forum Summer Meeting!

Welcome to the Grey group's 2024 cohort of FUSE interns, who have been arriving in Cambridge over the past few weeks.

Congratulations to Astrid Berge, PhD student, who won the best poster award at the RSC's NMR discussion group postgraduate meeting!

Congratulations to Clare, who has been elected as an international member of the US National Academy of Sciences! More information here.

Every year, the group hosts a cohort of undergraduate summer interns - mostly through the Faraday Institution's FUSE scheme. You can read about one of last year's interns here.
