Hi there! I'm Charly.

I’m a PhD candidate at EPFL, Switzerland. My research focuses on building secure foundations for our compute infrastructure. I am part of the Data Center System Laboratory, working under the supervision of Prof. Edouard Bugnion. You can reach out by email using the address charly.castes@epfl.ch.
