Research Homepage

I'm currently a postdoc in the group of Sanjam Garg at UC Berkeley, supported by a DAAD fellowship. Prior to that, I was a postdoc in the crypto group of Aarhus U
niversity, working with Ivan Damgård and Jesper Buus Nielsen. I finished my PhD in 2014 at the Karlsruhe Institute of Technology under the supervision of Jörn Müller-Quade. I am the 2014 winner of the biennial Erika and Dr. Wolfgang Eichelberger Dissertation Award. My research interests include lattice and coding based crypto as well as secure multiparty computation.

My PhD thesis, available here, is about the construction of advanced cryptographic primitives from coding problems.
