Later this month, we’re lucky to have Jari Saramäki visiting and speaking at the lab. Jari is an expert on temporal networks (I highly recommend the excellent review paper on temporal networks that Jari co-authored with past and future guest of the lab, Petter Holme). Jari is an associate professor at Aalto University and a highly…

[This is part II of a series, you can find the overview here] We all have a sense that privacy is important. A sense that our ability to freely express “who we are” is slowly eroded by large corporations and governments collecting data on our actions for purposes not clear to us (and maybe not to them either). But on…

Recently I’ve been thinking a lot about privacy. My own work focuses on what we can learn from dense data collected by volunteers at my university (DTU), and that means that privacy is something I think about a lot. What we’re learning from our amazing dataset shows that data channels are highly overlapping and even…

It’s not just the network structure that we care about. We want to understand network structure in order to get a handle on processes taking place on networks. That kind of processes is what next week’s two exciting (Monday and Tuesday October 6th and 7th, at 11am @ DTU) talks focus on. Both talks are…

This friday we’re lucky to have visitor Emilio Ferrara presenting a talk on identifying twitter bots.

As part of a Master’s project, Marta Magiera, a student in my group has developed a great tool for visualizing geo-data. Check it out below (looks best in 720p)

I often give the following writing advice to my students. Today, in honor of efficiency, I decided I’d put my advice in a blog post, so I can just link to it in the future. Unless you’re a great writer (in which case you don’t have to follow any rules), the structure of academic text is…

With collaborators at MIT (first author is Yves-Alexandre de Montjoye) we have just published a paper in Scientific Reports, The Strength of the Strongest Ties in Collaborative Problem Solving. The paper shows that networking (in the sense of building a larger network of weak ties) does not improve team performance under some circumstances. We showed…
