About

Starting January 2026, I will be a postdoc at OIST under the supervision of Carlos Cid. Before that, I completed my PhD in the Almasty and QI teams of the LIP6, in Paris, supervised by Alex Grilo and Damien Vergnaud. My subjects of interest are cryptography, quantum information and complexity theory. More precisely, some topics that I like are the Quantum Random Oracle Model, minimal assumptions for quantum cryptography (PRSs and variants), black-box reductions and separations in the quantum setting.

You can find my CV here.
