Dávid Visontai

research fellow

PhD (Lancaster University, 2013)

Biography:

During my PhD studies and postdoc years at Lancaster University I studied the dynamics of hybrid quantum systems using numerical calculations. I was part of a research project funded by the R&D department of British Petrol Ltd, in which we developed thermally triggered nanomaterials. In 2014 I returned to the Eötvös University as a research fellow with the help of a two year long postdoc grant given by the Hungarian Academy of Sciences and continued my research in molecular electronics and in pursue of candidate materials for topological insulator. Since 2016 I teach for undergraduate students basic programming skills, solid state physics and for graduate students data exploration and visualization at the University. I am also part of a team that provides IT support for various projects within the Faculty.
