My research interests include Internet TV and media distribution, traffic and cache management, and the evolution of the Internet architecture. Much of my current research focus on measurements and analysis of content popularity and access patterns for Video- and TV-on-Demand and the implications for caching strategies.
I have a Masters degree in computer science from Uppsala University (2002) and a PhD degree from Mälardalen University (2012).
