I’m an Associate Professor at DTU Compute. I’ve worked as a postdoc at the Institute for Quantitative Social Science at Harvard University and before that, I was at the Center for Complex Network Research at Northeastern University. My current research is about dynamic social networks. Currently we've handed out free cell phones to 1000 students at DTU and we're studying their interactions face-to-face, via telecommunications, and social networks. The most detailed social dataset in the world.
