Dr. Hichem Sahbi received his M.S. degree in theoretical computer science
from the University of Paris Sud, in Orsay, France in 1999, and his PhD in
computer vision and machine learning from INRIA/Versailles University,
France in 2003. From 2003-2006 he was a research associate first at the
Fraunhofer Institute in Darmstadt, Germany, and then at the Machine
Intelligence Laboratory at Cambridge University, UK. From 2006-2007, he
was a senior research associate at l'Ecole des Ponts Paris Tech, in Paris.
Since 2007, he has been a CNRS CR1 associate professor (and HDR) at Telecom
ParisTech/ENST, in Paris. Dr. Sahbi has participated in various scientific
committees, industrial, national, and international projects, and he is
the author of many publications. Dr. Sahbi's research interests include
statistical machine learning, computer vision, and image retrieval.
