My name is Or Sattath (in Hebrew: אור סתת) and I’m a senior lecturer (assistant professor) at the Ben-Gurion Computer Science department.

Previously, I was a postdoc at UC Berkeley, the Hebrew University and MIT. I finished my PhD. under the supervision of Prof. Dorit Aharonov at the Hebrew University, and Prof. Julia Kempe at Tel-Aviv University.

Research Interests

Quantum cryptography, complexity and algorithms. Theory of computer science at large.

Are you interested in doing a MSc., PhD.  or a post-doc in quantum cryptography? Send me an email. Full scholarships are available.



Mark Zhandry and I are organizing the tutorial “Quantum Computing Essentials for Financial Cryptographers” held in conjunction with Financial Cryptography (FC’22).

Program committees: QIP’21, QCrypt’20, The 1st Conference on Advances in Financial Technologies (AFT’19)QCrypt’18

Co-organizer of  The Mathematics of Quantum Computation workshop, IIAS, 2019.

I’m organizing the colloquium in our department — contact me if you have an interesting result you would like to present.


Current group members are:

  • Shai Wyborski (Ph.D.)
  • Amit Behera (MSc.)
  • Roy Radian (MSc.)
