About

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

I am a cryptographer in the Security group at IBM Research Europe in Zurich, where I have worked since 2015. From 2010–2015, I was a researcher at Inria 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). 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 quantum-safe cryptographic protocols based on the hardness of lattice problems. I have worked on the foundations of practical lattice encryption, digital signatures, and am currently interested in zero‑knowledge proofs and real-world privacy‑preserving primitives. A lot of my recent research has been funded by the ERC starting and consolidator grants, and some past research has received IACR Test-of-Time awards at Asiacrypt 2024 and Eurocrypt 2025. I also 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.
