PostDoc Jobs

[Note: Thanks for the many emails on this!! I will post new openings right here on this blog when they arise.]

I’m currently involved in two super-exciting projects that are currently hiring postdocs, so if you ever thought about moving to Copenhagen to do great science, now is the time. And with all these job postings, might even be able to bring a (scientifically outstanding) friend. As you probably know Denmark continues to be the happiest country on the planet, and the food & drink is amazing – with almost too many Michelin stars and a true abundance of hipster beer.

The scientific environment is also pretty great (if I have to say so myself). We’ve built an amazing group around the Copenhagen Networks Study (you may remember that we handed out 1000 smartphones to freshmen at DTU and collected network data for 2.5 years), and recently strengthened the efforts with the Copenhagen Center for Social Data Science (SODAS) at University of Copenhagen (where I’m now associate director). So we have a nice critical mass of interesting graduate students & postdocs with whom to spar, hang out, and grab lunch.

What I love about these projects is that they’re truly Data Science in the Drew Conway Data Science Venn Diagram (see below) sense of the word


In the language of the illustration above, we want you to have hacking skills + math and stats knowledge. What we offer is projects are carried out in close collaboration with people that have domain knowledge. (I’m beginning to have experience with this kind of project, and it’s completely amazing and refreshing to have a partner who can actually help place your data-driven results in context.)

The projects are:

  • Twitter Bots. This is the data-science component of a larger project, directed by political scientist, Prof Rebecca Adler-Nissen. The successful candidate will be associated with SODAS and work at closely with my group as well as political scientists exploring various qualitative aspects. The full project title is Digital Disinformation: Exploring the Influence of Disinformation on Western Public Debate. This is extra fun because I actually have some practical experience building twitter bots.
  • Network Analysis of case law from international courts. This one is in collaboration with Henrik Palmer Olsen at the faculty of law, and the successful candidate will be formally associated with both the faculty of law and my research group. Read more here.

We’re also collaborating with natural language processing expert Anders Søgaard on both of these projects. (Both networks have lots of text metadata associated with each node, so it’s kind of fantastic to have an NLP expert on the team).

Both positions are connected to a specific project where you’re expected to deliver certain results, but we support ‘blue sky’ research and once you’re set up, we welcome your ideas, and participation in ongoing research topics.

Action item: If you’re interested, send me an email!

PS. We’re also looking for a third postdoc in a more NLP minded project for the Data Transparency Lab, this one helmed by Anders. This project is about how well we can identify an author in large text corpus based on e.g. their tweets. There’s a great team on this one listed in Anders’ tweet below.


Esteban Moro Talk

Monday June 13th is shaping up to be an exciting day for data science in Copenhagen. I’ve already announced that Christo Wilson is giving a talk at DTU, but now I’m happy to add Esteban Moro to the speaker line-up for a fantastic double bill. (And Piotr’s PhD defense at 2pm that afternoon will also be quite an event)

Esteban Moro is a researcher at Universidad Carlos III de Madrid in the GISC group working on complex systems. On his superb blog he notes that “The fact that the systems under study are complex does not mean that its behavior cannot be understood or anticipated. I believe research must be interdisciplinary and close to real life problems and because of that, I do research in social networks, financial markets or viral marketing (complex enough!)”.

Esteban’s work is creative, inspiring, and always exciting (plus often covered in the press). We are lucky to have him. The details of Esteban’s talk are

  • Time Monday June 13th, 10:45am
  • Place: DTU, Building 321, 1st floor lab space

Title: Pace of change in urban social networks

Abstract: Urban communities are seen both as highly structured social settings as well as distinctly vibrant environments for interaction, where personal relationships are initiated, consolidated and, eventually, lost and replaced by new relationships. Here we investigate statistical relationships between the social structure of the urban community and the pace at which such structure changes over time. To this end, we analyze the 19-month evolution of the social interactions pertaining to urban communities in England, Wales and Scotland, as described by 700 million of mobile phones calls made among 20 million inhabitants. We find that different urban communities display not only distinct social structures but also alter such structures at widely different paces. Furthermore, we investigate the impact of this heterogeneity in the network varying structure on information diffusion processes by simulating SI models. Our results indicate that time to infection can be well predicted using only static variables of the network, such as the number of connections, leading to the conclusion that the observed vibrant mechanics in link creation have a negligible impact on the information diffusion in terms of geographical spreading.
