New:  Lattice Encryption and Signatures Tutorial

                   Kyiv --> New York --> San Diego --> Tel Aviv --> Paris --> Zurich

I am a cryptographer in the Security group at IBM Research Europe - 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.  This research was in part supported by an ERC starting research grant FELICITY (Foundations of Efficient Lattice Cryptography, 2015 - 2020) and is currently supported by an ERC consolidator grant PLAZA (Post-Quantum Lattice-Based Zero-Knowledge, 2021 - 2026).  

The Ph.D. students and Postdocs with whom I currently have the pleasure of working with are:

  • Maxime Plancon (Ph.D. student) Nov. 2020 - 
  • Patrick Steuer (Ph.D. student) Jan. 2022 - 

My previous students and post-docs (at IBM and ENS) were:

  • Ngoc Khanh Nguyen (Ph.D. student)
  • Ward Beullens (Postdoc)
  • Gregor Seiler (Ph.D. student)
  • Jonathan Bootle (Postdoc)
  • Rafael del Pino (Ph.D. student)
  • Pierrick Meaux (Ph.D. student)
  • Thijs Laarhoven (Postdoc)
  • Thomas Prest (Ph.D. Student)

  • 2022: Crypto
  • 2021: PKC, TCC
  • 2020: Crypto, SCN
  • 2019: PQCrypto, Crypto, CCS, SAC
