Microelectronics Group



PhD in Physics (1995) – Institute of Electronics, Bulgarian Academy of Sciences, Sofia, Bulgaria
Several years research experience in Universities and research institutions in Sofia (Bulgaria), Sankt-Petersburg (Russia), Gothenburg (Sweden), Manchester and Birmingham (UK)


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
