Currently, I am PostDoc at Horst Görtz Institute for IT-Security at Ruhr-Universität Bochum and Interdisciplinary Coordinator for the DFG-funded research training group UbiCrypt. From 2011-2014, I was research associate in Jens Groth's security group at University College London. In 2011, I finished my PhD at Ruhr-Universität Bochum on secure digital signature schemes in the standard model.
