About

My research addresses the construction and cryptanalysis of quantum-secure schemes and provably guaranteeing their security in the appropriate security models.

I am affiliated to the Institute for Quantum Computing (IQC) as a post doctoral researcher at the Department of Combinatorics & Optimization at the University of Waterloo in Waterloo, Ontario, Canada. I interned at Microsoft Research, Redmond (US), during the summer 2019. Before, I was a post doctoral researcher in the Cryptography and computer algebra group at TU Darmstadt, Germany, where I received my Ph.D. in September 2018 under the supervision of Johannes Buchmann from TU Darmstadt.

I have been the principal submitter of qTESLA, a quantum-secure digital signature scheme that had been submitted to NIST’s post-quantum standardization effort. It has been accepted as a candidate of the second round as one of nine out of 20 schemes, but did not advance to the third round. For more information please visit qtesla.org.
