Department of Network and Data Science

The Department of Network and Data Science at Central European University provides an organizational platform for research in network science, with a special focus on applications to practical social problems. The department offers a PhD program and an Advance Certificate Program in Network Science. 

Data Science tools and the Network Science approach offer a unique perspective to tackle complex problems, impenetrable to linear-proportional thinking.The data deluge of our times has opened up unprecedented opportunities to study and understand structure and function of social, economic and political systems. The concept of networks has become indispensable in several social science disciplines. Data-driven network science aims at explaining complex phenomena at larger scales emerging from simple principles of making network links. A key element of the mission of the Department is to work across disciplines to bring network and data science tools to many fields of the social sciences.

The Department of Network and Data Science translates these ideas into research projects - our faculty have won several major grants, from European Union and US funding agencies.

CNS announces a new seminar series

The Center for Network Science
announces a new seminar series, with bi-weekly meetings.
This seminar series aims at bringing together the
growing community of those interested in networked phenomena.
We aim to provide a social platform to the CEU part of this community,
while at the same time we also strive to increase the cohesion of the

Five-year ERC grant funds research into social network effects on economic activity

As announced in CEU news recently, Professor Adam Szeidl of CEU’s Economics Department won a five-year "Networks" grant from the European Research Council.

Enjoy, and Happy Holidays!

Albert Laszlo Barabasi joins CEU CNS as part time faculty

Albert Laszlo Barabasi joins the CEU Center for Network Science as part time faculty. His appointment starts 2011 May 1st, and he will visit CNS regularly during the process of building substantive research capacities towards network science at CEU. His engagement at CEU CNS includes overseeing the development of a network science research strategy at CEU, help CNS secure research funding, and teaching one course on the fundamentals of network science.

Our findings show the fragmentation of European network science

There is a general sense of fragmentation when one compares European science to the American one. We set out to test the extent of fragmentation in the European network science field. We found that European netowrk science is highly fragmented, wih many small components arranged mostlty along country lines and disciplinary boundaries. Based on our analysis of citaiton performanve, it seems that the larger the component the higher the citation score.

Using network science at the U.S. Army

A recent article on NPR reports the use of network science in the Iraq and Afghanistan wars: "The U.S. military's biggest success so far in the use of network analysis was the capture of Saddam Hussein in December 2003. He was found after soldiers diagrammed the social networks of his chauffeurs and others close to him.

Do you know your network?

A part of the PhD course "Understanding Networks" we map the personal network of each participant, using the ties recorded in our Facebook account. The way your friends are connected to each other reveals intersting reflections: Are there distinct subgroups? From which aspect of your personal history do they come from?

The geography of scientific collaboration

A recent article of Loet Leydesdorff & Olle Persson charts the geography of scientific collaboration. Maps and the software to make such maps is made available by the authors.
