Master’s Student Selected as a Student Volunteer for Supercomputing 2025

Master’s student Miguel Freitas, advised by Prof. Lúcia Drummond, has been accepted into the Student Volunteers program for the Supercomputing 2025 (SC25) conference.

Regarded as the premier international conference for High-Performance Computing (HPC), SC25 will take place from November 16th to 21st in St. Louis, Missouri, USA.

Student volunteers play a crucial role in the event’s organization, supporting attendees and the conference as a whole. In return, they have the unique opportunity to attend technical presentations, explore the latest industry technologies, and, most importantly, build lasting professional connections with researchers and experts from the global HPC community.

We congratulate Miguel on this significant achievement and wish him an excellent conference experience.
