Biography
Malika Izabachene is an Associate Professor with the ICI team at ETIS lab and with the Department of Computer Science
at Cergy Paris University since September 2025.
Her research focuses on cryptography, with emphasis on homomorphic encryption, post-quantum cryptography, and
privacy-preserving protocols, aiming to develop secure and practical solutions for privacy preserving applications.
From 2020 to 2023, she served as Chief Cryptographer at Cosmian, a Paris-based start-up, overseeing the design of post-quantum cryptographic primitives and secure multi-party computation frameworks. She was also involved in teaching at École Polytechnique until September 2025.
Prior to that, she was a researcher at CEA (2014–2020), and held postdoctoral positions at LORIA, the University of Versailles, and Queensland University of Technology, focusing on electronic voting systems, anonymous credential schemes, and advanced post-quantum cryptography. She received her PhD in 2009 from Université Paris VII, where she conducted her doctoral research at ENS Paris.
