Research Description

My group uses Electron Paramagnetic Resonance (EPR) Spectroscopy to investigate the structure of novel materials and proteins. Our work is unashamedly collaborative and brings together biologists, chemists, materials scientists and physicists. There are 3 main themes:

Characterisation of the electronic structure and properties of bismuth dopants in silicon by EPR spectroscopy (Morley et al Nature Materials 2013, Balian et al Physical Review B 2012, Morley et al Nature Materials 2010).

Characterisation of the structure and properties of thin films of copper phthalocyanines by EPR Spectroscopy (Warner et al Nature 2013, Warner et al ASC Nano 2012).

Combining X-ray crystallography, molecular dynamics and nitroxide spin-labeling EPR spectroscopy to obtain and verify structures of proteins in solution (Bagneris et al Nature Communications 2013, Webster et al Nucleic Acids Research 2012, Phan et al Nature, 2011, Grohmann et al Journal of the American Chemical Society 2010).
