Garazi Muguruza Lasa

I’m a fourth (last!) year PhD candidate supervised by Florian Speelman, Paola Grosso and Christian Schaffner, expected to graduate in July 2025. My office is located at Centrum Wiskunde & Informatica.

I’m interested broadly in quantum cryptography; I like finding relations between cryptographic tasks using information theory, thinking about security, new functionalities…
