"Nowadays, telecommunications providers and IT companies collect vast amounts of electronic data about us. These databases may contain sensitive personal data, which means they also carry risks, but at the same time they can be an incredibly valuable source of information for the social sciences. Balázs Lengyel, Senior Research Fellow at the Institute of Economics of the HUN-REN Centre for Economic and Regional Studies, and his colleagues are analysing some of this data with the support of the Momentum (Lendület) Programme. The researcher has won a Momentum grant for the second time – now in the advanced category – and is currently researching innovation and inequality in dynamic urban networks." - writes the Hungarian Academy of Sciences.
