About

My name is Or Sattath (in Hebrew: אור סתת) and I’m a senior lecturer 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. or PhD. in quantum computing? Send me an email.
