Publications

Our work focuses on understanding the physics of disordered semiconductors: small molecules, polymers, hybrids, and the like. We implement precision measurement techniques and fabricate prototype devices within research themes of thermoelectrics, charge transport, spintronics, and nanomechanics.
My work has translational impact on science policy in UK Government.
