Narseo Vallina-Rodriguez


Since July 2013, I'm a PostDoc Researcher at ICSI-Berkeley working on Netalyzr for Android. My new website can be found here.

Qualcomm Innovation Fellow, 2012-2013

Short Bio:

I have been a PhD student in the Computer Laboratory, at the University of Cambridge under the supervision of Professor Jon Crowcroft since February 2009. In 2012, I was awarded with a Qualcomm Innovation Fellowship. I am a member of the Networks and Operating Systems group, which is a subdivision of the Systems Research Group, and member of Fitzwilliam College, in which I was an active member of the graduate community holding different possitions in the MCR committe between 2010 and 2012. My research is mainly focused on mobile systems optimizations (see related work) but I also keep my nose on Signpost project.

I obtained a B.S./M.S. in Telecommunication Engineering from the University of Oviedo, Spain, in 2007. My M.S. Thesis was completed at the University of Cambridge as a visitor student working on Haggle Project (August 2006-February 2007), also under the supervision of Professor Jon Crowcroft. My work in Haggle was awarded with Honors Mentions by the University of Oviedo.

After graduating in 2007, I moved to Barcelona as an intern in Telefonica Internet Research Group with Dr. Pablo Rodriguez where I was working on IPTV performance on WiFi and Multipath Video Streaming for 10 months. After that experience, I joined Vodafone R&D (UK) with David Pollington in the Devices Team working on Intelligent Services design.

I also completed an internship at Deutsche Telekom Labs, TU-Berlin, with Dr. Pan Hui. Between July 2011 and September 2011, and June 2012 to October 2012, I also completed two fruitful internships at Telefonica Research with Dina Papagiannaki and Yan Grunenberger.
