Jim Bagrow Visit and Talk
This week my good friend & collaborator James Bagrow (assistant professor at University of Vermont) is visiting the group. He’s an excellent speaker, and we’re lucky enough that he’s agreed to give a talk as part of his visit. If you’re anywhere near Copenhagen, his talk is worth the trip out to DTU. Here are the…

Tracking Human Mobility using WiFi signals
When I started working on understanding social systems, privacy really wasn’t on my mind. (I generally want to write down equations, understand the universe and all that). But one of the central realizations arising from our SensibleDTU experiment is that privacy needs to be an important part of this kind of research. I’ve written about this…

What it means to be a pro
I just love this quote which uses a Tiger Woods anecdote to illustrate what it means to be a professional. It’s from The War of Art by Steven Pressfield (a great read, btw). With four holes to go on the final day of the 2001 Masters (which Tiger went on to win, completing the all-four-majors-at-one-time Slam),…

New Design
The header graphic (it’s apparently called that even though it’s displayed on the left) accompanying my updated site was created by Andrea Cuttone, as PhD student in my group, using his cool python geo visualization toolkit geoplotlib. It’s a Voronoi construction based on data from the Copenhagen Networks Study. The full image is displayed above.

Privacy Part II: Some examples of why privacy is important.
[This is part II of a series, you can find an overview here] There are many reasons why privacy is important. I will not try to cover them all here, but instead I have chosen two central topics, which I find particularly important. “I have nothing to hide, so why should I care?” This one…

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…

Privacy Part I: Why everyone is complaining, but no one is taking action.
[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…

Some thoughts on privacy. Part 0
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…
