I was an expert in Integrated Management, i.e., the management of networks, systems, and services in a federated/integrated manner. From 1996 to 2015, I worked successively on:
I was a Member of the Editorial Boards of IEEE Transactions on Network and Service Management (TNSM), Journal of Network and Systems Management (JNSM), IEEE Cloud Computing Magazine, EAI Endorsed Transactions on Cloud Systems (ToCS), and International Journal of Web Services Research.
I was a Guest Editor of six special issues of journals and magazines, including "Recent Advances in Autonomic Communications" for IEEE Journal on Selected Areas in Communications and "Self-Organizing and Self-Managing Networks, Systems, and Services" for IEEE TNSM.
I co-founded the SASO conference series (IEEE International Conference on Self-Adaptive and Self-Organizing Systems), chaired the Steering Committee of its first edition from 2005 to 2007, and remained a Member of the Steering Committee until 2012.
I co-chaired SASO-biz 2008, SelfMan 2006, ECOWS 2005, SelfMan 2005, GNEW 2004, and PFLDnet 2003. The International Grid Networking Workshop (GNEW 2004) that I co-organized at CERN was the event of the year in Grid networking in 2004.
I was on the Steering Committees of five conferences and workshops. I was on the Program Committees of dozens of conferences and workshops, including IEEE International Conference on Cloud Computing (CLOUD), International Conference on Network and Service Management (CNSM), IFIP/IEEE International Symposium on Integrated Network Management (IM), IEEE/IFIP Network Operations & Management Symposium (NOMS), and IEEE International Conference on Big Data (IEEE BigData).
I was a Senior Member of IEEE and ACM, and a Member of IFIP WG6.6.
I worked alternatively in research labs and the "real world", often acting as a bridge between academia and industry. I had a keen interest in technology transfer.
From 2011 to 2015, I was an Academic Guest at Katerina Argyraki's newly created Network Architecture Lab at EPFL, where I worked on cloud management, big data analytics, multi-cloud troubleshooting, distributed diagnosis algorithms, and privacy-compliant diagnosis.
From 2012 to 2013, I was Co-Founder, CEO ad interim, and CTO of LakeMind, a startup that developed a cloud service to perform cross-provider diagnosis in public clouds.
In 2010, I received a one-year innovation grant from EPFL to work on cross-provider diagnosis in public clouds. I was hosted by Willy Zwaenepoel's Operating Systems Lab at EPFL, where I cooperated with Katerina Argyraki.
From 2006 to 2009, I was a Senior Consultant in Business Organization and IT with NetExpert, Switzerland, primarily working in business process modeling (technical competence management), project management, and IT/network service guarantees. I also did some independent research in self-managing networks, autonomic systems, and self-adaptive services.
From 2005 to 2006, I was an Adjunct Professor at the University of Quebec in Montreal (UQAM), Canada, advising for two Grid projects and cooperating with Omar Cherkaoui.
From 2004 to 2005, I was an external Lecturer with the School of Computer & Communication Sciences at EPFL. I taught information systems and middleware to M.S. students, and C and Java programming to B.S. students.
From 2002 to 2004, I was the Technical Manager of the FP5/IST DataTAG Project, a €4M project funded by the European Union. Based at CERN in Geneva, Switzerland, I coordinated the R&D activities (Grid networking and middleware for data-intensive transoceanic Grids) of 50 FTEs spread over five countries (France, Italy, Netherlands, Switzerland, and UK) and 10 research teams, of which 25 FTEs were fully funded. I was the liaison to related U.S. projects at Caltech, Lawrence Berkeley National Lab, Stanford University (SLAC), etc. These projects led the foundations for the networking infrastructure that made it possible to distribute all over the world the huge amount of data generated by the LHC accelerator at CERN. These fast long-distance networks played an important role in the quest for the Higgs boson and its discovery in 2012.
From 2000 to 2001, I was a Principal Technical Staff Member with AT&T Labs - Research in Florham Park, New Jersey, USA. I did some research on Web-based management, push technologies, and management information modeling. I also consulted internally to business units in network and service management.
From 1996 to 2000, I went back to university for my doctorate and worked as a Teaching and Research Assistant with Jean-Pierre Hubaux at the Laboratory for Communications & Applications at EPFL. An enhanced version of my Ph.D. dissertation ("Web-Based Management of IP Networks and Systems") was published as a monograph by Wiley.
From 1990 to 1996, I was an Analyst at the European Centre for Medium-Range Weather Forecasts (ECMWF) in Reading, UK, which then hosted the 4th largest civilian data archive in the world. I took part in network and systems management, security, and software development activities in a high-availability 24/7 environment. From late 1993, I initiated and generalized the use of Web technologies at ECMWF. In early 1995, I put into production one of the first fully operational Web-based intranets in Europe.
From 1988 to 1990, I worked as a Systems Engineer and Software Developer on the geographic information system of Grand Lyon, a large urban area in France.
