Networking

Location data on two apps enough to identify someone

Columbia and Google researchers demonstrate that geotagged posts on just two social media apps are enough to link accounts held by the same person.

Net neutrality and Internet economics

Using economic modeling, researchers show how profit-motivated decisions by network providers undermine net neutrality.

Paper coauthored by Henning Schulzrinne earns Test of Time Award at IEEE INFOCOM

“An Analysis of the Skype Peer-to-Peer Internet Telephony Protocol” (2006) was first paper to use traffic analysis to reverse-engineer an intentionally obscured network application.

    Dean Boyce's statement on amicus brief filed by President Bollinger

    President Bollinger announced that Columbia University along with many other academic institutions (sixteen, including all Ivy League universities) filed an amicus brief in the U.S. District Court for the Eastern District of New York challenging the Executive Order regarding immigrants from seven designated countries and refugees. Among other things, the brief asserts that “safety and security concerns can be addressed in a manner that is consistent with the values America has always stood for, including the free flow of ideas and people across borders and the welcoming of immigrants to our universities.”

    This recent action provides a moment for us to collectively reflect on our community within Columbia Engineering and the importance of our commitment to maintaining an open and welcoming community for all students, faculty, researchers and administrative staff. As a School of Engineering and Applied Science, we are fortunate to attract students and faculty from diverse backgrounds, from across the country, and from around the world. It is a great benefit to be able to gather engineers and scientists of so many different perspectives and talents – all with a commitment to learning, a focus on pushing the frontiers of knowledge and discovery, and with a passion for translating our work to impact humanity.

    I am proud of our community, and wish to take this opportunity to reinforce our collective commitment to maintaining an open and collegial environment. We are fortunate to have the privilege to learn from one another, and to study, work, and live together in such a dynamic and vibrant place as Columbia.

    Sincerely,

     

    Mary C. Boyce
    Dean of Engineering
    Morris A. and Alma Schapiro Professor
