Bio

Guillermo was awarded a Marie Skłodowska-Curie Actions grant in 2017 to pursue his PhD at the University of Leeds, working under the guidance of Prof. Mohsen Razavi. He successfully defended his thesis in 2021 and received the prize for the best thesis in the School of Electrical Engineering that year.

After completing his PhD, Guillermo joined Prof. Marcos Curty’s group at the University of Vigo for a brief postdoctoral stay. Then, he joined Prof. Kiyoshi Tamaki’s group at the University of Toyama for one year as a JSPS Postdoctoral Fellow. Currently, he is a postdoctoral researcher at the Department of Signal Theory and Communications of the University of Vigo. His main research interest is the security of quantum key distribution.
