Education
Xavier Grehant
I am a PhD student at Telecom ParisTech since 2006. I obtained a Dipl. Ing. from Telecom ParisTech in 2005.
In 2004 I worked in biometrics as a research associate at Arizona State University.
In 2005 I worked as a student consultant for a startup company. I invented and demonstrated an algorithm for face fiducial points recognition. I received the award "Label Ingenieur": engineering mission of the year.
I worked at CERN openlab as HP Labs fellow from 2006 to 2009 where I carried out most of the work for my PhD on Grid Resource Allocation. Some of my contributions are published in international scientific conferences. Others are in the process of being published in international scientific journals. They include:
- A formal model for resource allocation.
- A formalism of the MAD (Multiple Administrative Domains) problem in distributed computing.
- An architectural pattern as a proven solution to this problem.
- Developed and lead the development of virtual machines and services deployment systems as elements of this architecture.
- Algorithms for cache performance prediction in presence of cache thrashing.
- Stochastic and probabilistic analysis of memory accesses.
I made these contributions and evaluated them by means of formal proofs and simulations.
In 2009 I received a first prize award from Hypios.com for an algorithm in behavioral targetting and a runner-up prize for a social mechanism based on user incentives.
