Haakon Ringberg^[1]

I am a Ph.D. student at Princeton University in the department of Computer Science. I am co-advised by Kai Li and Jennifer Rexford. I have been fortunate to collaborate with Christophe Diot, Augustin Soule, and Fernando Silveira of Thomson Research; Nick Duffield, Balachander Krishnamurthy, and Patrick Haffner of AT&T Labs Research; Matthew Roughan; Matthew Caesar. I have broad interests in computer science, but have recently been working on network anomaly detection.

Naming

The full story behind my name(s) is a bit long, so I'm going to give you the heavily abridged version. I am a U.S. and Norwegian dual citizen, but have different legal names in the two countries. In the U.S. I am legally "Haakon Andreas Ringberg Larsen" whereas I am "Håkon Andreas Ringberg" in Norway. I intend to change my legal name to "Haakon Ringberg" in both countries, which is why I am publishing under that name. That's it. Aren't you glad I didn't give you the full version? :-)
