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 40 group members including 20 PhD students (9 students being co-supervised) and 17 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 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.

Congratulations to Dr Aman Torayew who succesfully defended his PhD viva in March. We wish him the best of luck for his future career.

Welcome to Dr Quentin Jacquet who joined the group in March. He is working on new anode materials and lithium ion diffusion in Li-ion batteries.

Welcome to Dr Supreeth Nagendran who joined the group in February with the Newton International Fellowship, the title of his research proposal is 'Layered Double Hydroxides as Electrodes for Supercapacitors: A study on the charge-discharge mechanism'.

Welcome to Jennifer Thuillier who joined the group in January as a research assistant. She will be working predominantly on niobium tungsten oxide as an anode material.

Congratulations to Dr Josh Stratford for his successful viva in December!

Welcome to Dr Farheen Sayed who joined the group in December. She will study solid state electrolytes, in particular the interphase between the solid electrolyte and the anode or cathode.

Congratulations to Dr Yanting Jin for her successful viva on the 8th November!

Welcome to all new PhD students Jennifer Allen, Euan Bassey, Haydn FrancisVictor Gonzalez, Sundeep Vema, Evelyna Wang, and Bo Wen who joined Grey Group in October.

Welcome to all Master students: Dominic Hey, Dongxun Lyu, Conrad Szczuka and Part III students: James Capel, James Ellison, Ben McConnell, James Richardson, and Tommy Sun who joined Grey Group in October.

Welcome to Dr Svetlana Menkin who joined the group in October. She will study the lithium-dendrite growth mechanisms and the prevention of dendrite formation by the creation of an artificial solid-electrolyte-interphase (SEI) on the lithium-metal anodes, as well as charge storage mechanisms of supercapacitors.

Congratulations to Steffen Emge for winning the best poster award at the Materials RIG Showcase Symposium held on Thursday 27th September 2018.

Congratulations to Dr David Halat for winning one of the Departmental Outstanding PhD Thesis Awards for 2017 - a recognition of the remarkable contribution of his PhD thesis in the field of material science! The awards were given to the recipients during the Materials RIG Showcase Symposium held on Thursday 27th September 2018.

Welcome to Dr Chris O'Keefe who joined the group in August. His research focuses on the development and application of solid-state NMR techniques to improve the efficiency of the in situ investigation of battery materials.
