Ignasi Paredes Oliva

Short Bio

I received my B.Sc. and M.Sc. degree in Computer Science Engineering on July 2009 from the Technical University of Catalonia (UPC-BarcelonaTech). I joined the Load Shedding in Network Monitoring Applications group inside the Broadband Comunications Research Center (CBA) of UPC-BarcelonaTech on July 2007. During my first two years in the group, I was involved in the SMARTxAC project, a traffic monitoring platform that analyses all the traffic between the Catalan and the Spanish National Research and Educational Networks (Anella Científica and RedIris, respectively). In September 2009, I started my Ph.D. in the same university, supervised by Dr. Pere Barlet Ros and Prof. Josep Solé Pareta, focusing on network traffic monitoring and analysis. I was a visiting researcher in DANTE (United Kingdom, Winter 2009) and ETH (Switzerland, Summer 2010), where I worked with Maurizio Molina and Dr. Xenofontas Dimitropoulos, respectively. My research interests are particularly centered on addressing current challenges for network security in backbone networks (e.g., impact of sampling on anomaly detection or anomaly validation).
