From July 2023 to October 2023, I visited the Berkeley NetSys Lab at the University of California, Berkeley, under supervision of Prof. Dr. Sylvia Ratnasamy and Prof. Dr. Scott Shenker.

From February 2016 to July 2016, I was a visiting researcher at the Broadband Wireless Networking Lab, under the supervision of Prof. Dr. Ian F. Akyildiz, working on Network Virtualization for 5G Software-Defined Cellular Systems.

Prior to joining ETH Zürich, I received a Master's Degree in Telecommunication Engineering (2018) and a Bachelor's Degree in Science and Telecommunication Technologies Engineering (2016), both from Universitat Politècnica de Catalunya (UPC) in Barcelona, Spain.

I have also worked on industry projects for organizations like Cloudflare (2023), IBM (2017), and CERN (2015).
