Research Interests

Before joining the Cavendish Laboratory at Cambridge University I was working mainly on thin-film structures and devices utilizing the unique properties of complex metal oxides such as high-temperature superconductivity (YBa2Cu3O7), ferroelectricity (Ba1-xSrxTiO3), colossal magnetoresistance and spin-polarisation (La2/3Ca1/3MnO3), magneto-optical response (Y3-xBixFe5O12). Here at the Microelectronics Research Centre I take the responsibility of managing the cleanroom facilities with more than 50 regular users. I do also research on laser writing as method for direct patterning of device structures.
