Kevin Vermeulen

I am Kevin Vermeulen, a CNRS researcher at LIX, Ecole Polytechnique, Palaiseau, France. Until March 2025, I was a CNRS researcher at LAAS-CNRS.

I am interested in building networked measurement systems to better understand and improve the Internet.

In particular the systems and techniques that I develop are related to these different topics:

• Network topology
• Network performance
• Network security
• Traffic engineering

Before joining the CNRS, I was a postdoc at Columbia University working with professor Ethan Katz-Bassett.

I obtained my doctorate in 2020 under the supervision of professor Timur Friedman at Sorbonne Université.

I am the maintainer of the Reverse Traceroute system. The system currently runs more than a million reverse traceroutes per day in coordination with the M-Lab NDT speedtests. The data are publicly available here.
