Laurent Vanbever
Assistant Professor @ ETH Zürich


I am an assistant professor at ETH Zürich since January 2015. At the moment, I do not have open PhD positions. Although, I do have a few positions available for visiting students. Feel free to contact me if you are interested.

My research interests lie at the crossroads of theory and practice, with a focus on Software-Defined Networking and Internet routing. Overall, I aim at making networks both more performant and easier to manage.

I completed my PhD in computer science in October 2012 at the University of Louvain under the guidance of Olivier Bonaventure. My thesis is entitled "Methods and Techniques for Disruption-Free Network Reconfiguration". After my PhD, I spent two years at Princeton University working with Jennifer Rexford as a postdoctoral researcher.

Prior to my PhD, I earned my master degree in computer science from the University of Louvain in 2008. I also earned a master degree in management from the Solvay Brussels School of Economics and Management in 2010.

You can find more details about me and the work I am doing in my resume, fact sheet and list of publications.

To contact me, drop me an email at (preferred) or .
