I have spent the last 30 years analyzing internet data and building tools to improve network performance and availability. I am also an active contributor to the research community (mostly through ACM SIGCOMM) and I have been an advocate of making data publically available for researchers (in particular as M-LAB executive sponsor at Google -- M-LAB is a non profit organization funded in part by Google).
I have a PhD in Computer Science (INP Grenoble, FRANCE, January 1991) and an HDR (INP Grenoble, September 1996). I joined INRIA Sophia Antipolis in October 1993 where I worked with Christian Huitema and Walid Dabbous on internet protocols and applications. This is when I started working on multicast, and designed a peer-to-peer multicast game on the Mbone . At INRIA, I also worked on automatic protocol generation from ESTEREL formal descriptions. From October 1998 to April 2003, I worked at Sprint Advanced Technology Labs in San Francisco. I was given the opportunity (thanks Franck de Nap and Bryan Lyles) to build a new research group which task was to understand performance of the Internet and help with backbone engineering and design. Outstanding experience with amazing people. We designed a unique measurement infrastructure made of GPS synchronized packet collection, routing information, SNMP data, and active probing. Everything had to be invented at the time (starting with hardware). At Sprint, we also did seminal work on DiffServ together with Martin May and Jon Crowcroft. In 2003, I moved to INTEL Research in Cambridge where the objective was to create a multi-disciplinary research group to help INTEL identify and develop promising new technologies. This is where we started Pocket Switched Networks (also known as "Haggle"), and designed new anomaly detection techniques for the Internet, among other cool projects. I joined THOMSON in Paris in October 2005 to launch a research lab on new communication services and platforms for contents delivery. The Paris lab pioneered research on home networking, home (nano) data centers and CPE added-value features in general. From July 2008 to April 2009, I acted as the CTO of Thomson Corporate Research. In May 2009, I became Chief Scientist for Thomson, in charge of long term innovation strategy and relationship with academics (among other stuff ). In this position I discovered a whole range of new research domains, e.g. multimedia communications, video coding, color coding, image analysis. In January 2010, THOMSON became TECHNICOLOR. In 2011, I created a research lab in Palo Alto. The Palo Alto lab was performing research on user understanding, privacy, and recommendations. I joined SAFRAN in September 2015 as CTO of SAFRAN Analytics, a new entity created to develop a data culture in the company. I have been appointed "emeritus expert", the highest level of technical expertise inside SAFRAN.
In June 2018, I moved back to California to join Google, where I have built a telemetry team focused on statistical analysis of network data. We have designed and deployed two innovative products:
We co-invented the Network Intelligence Center which was the first customer facing data analytics tool in the Cloud (according to Gartner). We designed accurate loss and latency dashboards (real-time) using statistical inference (with a mathematically proven 2% error).
More recently, we launched a real-time global network anomaly detection tool that automatically mitigates network problem, relying on simple and scalable statistical analysis. We spend less than 8mns between detection and automated mitigation, which is also unique in industry. More recently we have been able to automatically repair and restore network equipments we had initially drained to minimize impact on network capacity.
According to Google Scholar, my H index is 84. I am an ACM Fellow since 2005.

Most of my Publications and reports are available online. Google Scholar has the most accurate information about my parents and publications though.
