About me

Research

Advisor: Alex C. Snoeren.

Most recently I've been getting caught up in wireless research, joining the likes of Alex Snoeren, Geoff Voelker, Mikhail Afanasyev, Stefan Savage and Yu-Chung Cheng. We diagnose enterprise wireless networks (Jigsaw). Additionally, together with Yuvraj Agarwal and Alex Snoeren, I'm analysing the performance of VOIP in wireless networks, aka Softspeak.

I did two internships with AT&T Research in 2005 and 2006, in both cases working with Kobus van der Merwe and other good people. We worked on distributed denial of service attack mitigation and fine-grained route control for ISPs.

The first project that I worked on at UCSD was Platypus, a system that enables increased routing flexibility for end hosts and edge networks, while providing the control that ISPs want over such source-based path selection. I implemented a framework in which all this takes place, guided by policy.

In 2004, I was a scientific programmer with the Intelligent Interactive Distributed System project, at the Vrije Universiteit Amsterdam.

During 2003, I did research and development in interdomain routing on the Atoms project at CAIDA, funded by NLnet Labs.

From 1996 to 2002, I was the lead scientific programmer with the Globe project, at the Vrije Universiteit Amsterdam, headed by Maarten van Steen and Andy Tanenbaum.
