Research Interests:

Dr Alan Drew is a recently appointed Leverhulme Fellow in the Condensed Matter Physics Group (CMP) at Queen Mary, University of London and a 'collaborateur externe' (Visiting Research Fellow) in the Physics Department, University of Fribourg. His main research interests are using spin sensitive probes situated at central facilities to characterise and understand the fundamental properties of materials, as well as laboratory based research (e.g magnetic, structural and electrical characterisation, thin film growth, raman/IR spectroscopy, electro/photo luminescence). His main interests are understanding spin and charge carrier dynamics in organic materials and the properties of materials with novel quantum mechanical states. Further details can be found on his website: http://www.mmp.ph.qmul.ac.uk/~drew/
