The European Research Council has awarded me the ERC starting grant for my research on global networks of corporate control. The project is titled Corporate Network Governance: Power, Ownership and Control in Contemporary Global Capitalism. The ERC grant supports young academics who have the proven potential of becoming independent research leaders. The EUR 1.5 mio grant allows me to build a new research team over the coming five years.
