I am a computer scientist broadly interested in networking. More particularly, my research aims at understanding, designing, and developing solutions for efficient networking, mostly in the context of content delivery in wireless and wired networks. Please see below more information on my research on Information-centric networks, dynamic spectrum access, and mobile opportunistic networks.

On March 2017, I am granted the title of Docent in Computer Science at the University of Helsinki, Finland.

As of March 2017, I am on N2Women Board as one of the mentoring co-chairs.
