About

Kyiv → New York → San Diego → Tel Aviv → Paris → Zurich

I am a cryptographer at IBM Research in Zurich, where I have worked since 2015. From 2010–2015, I was an Inria researcher (chargé de recherche) in the crypto group at the École Normale Supérieure in Paris, and prior to that, a post‑doc in the Foundations of Computing group at Tel‑Aviv University (hosted by Oded Regev) from 2008–2010. I received my Ph.D. from the University of California, San Diego (advised by Daniele Micciancio) in 2008.

My main research focus is on designing efficient cryptographic protocols based on the hardness of lattice problems. In particular, I have worked on the foundations of practical lattice encryption, digital signatures, and am currently interested in zero‑knowledge and various privacy‑preserving primitives. I co-led the CRYSTALS team which produced the CRYSTALS-Kyber (ML-KEM) and the CRYSTALS-Dilithium (ML-DSA) NIST standards for post-quantum encryption and digital signatures. I also contributed to the FALCON signature scheme, which was chosen to be a NIST standard under the name FN-DSA.
