About me

I am currently working at Talaia Networks, a spin-off of UPC-BarcelonaTech I co-founded. Check Network Polygraph, a network visibility service that we offer.

Previously I worked as a researcher at the Dept. of Computer Architecture of Technical University of Catalonia (UPC), where I got a PhD in computer science in March 2012.

My research interests were focused on efficient network traffic analysis algorithms and the design and architecture of general-purpose passive network monitoring systems. I was part of the Load Shedding in Network Monitoring Applications group inside the Advanced Broadband Communications Center, a research center of UPC.

Teaching

I used to teach Metodologia i Programació Orientada a Objectes (an OOP course) at Telecom BCN (the telecommunications engineering school of UPC) and Us de Sistemes Operatius (a course on the services and utilities provided by operating systems) at Barcelona School of Informatics (FIB) of UPC.
