I'm an Associate Professor at DTU Informatics, at
the Technical University of Denmark. A physicist by training, my
interests have slowly shifted towards complex
networks and
massive datasets, and I'm currently working in the intersection
between physics, sociology, and computer science.
My work focuses on understanding the structural and dynamical
aspects of complex network topology, as seen from a statistical
standpoint. I'm currently working to understand temporal dynamics
of in multiplex networks based on data a large scale sociometer
experiment (High Resolution
Networks),
funded by the Villum Foundation.
Previous work has focused on communities in
networks Nature (Ahn, Bagrow and
Lehmann.
Nature doi:10.1038/nature09182, 2010), multipartite
networks (Lehmann,
Schwartz, Hansen. PRE 78, 016108, 2008) and understanding the
type of correlations that scientific authors and collaborations
impose on the (citation) links between the publications
(Lehmann, Jackson, Lautrup. Nature 444, 1003, 2006). I'm a
graduate of the Niels Bohr Institute ( B.Sc,
Physics 2001 [pdf], M.Sc,
Physics, 2003 [pdf]) and the Technical University of
Denmark (
Ph.D., Complex Networks, 2007 [pdf]).
In the past, I've worked as a Postdoctoral Fellow
at Institute for
Quantitative Social Science at Harvard University and
the College of Computer and
Information Science at Northeasthern
University; before that, I was at Laszlo
Barabási's Center for
Complex Network Research at Northeastern University and
the Center for Cancer
Systems Biology at the Dana Farber Cancer
Institute.
