Background
Before joining DoCoMo USA Labs in 2002, I worked at a start-up in optical
data storage called Calimetrics. From 1998 to 2000 I did a post-doc at
Stanford University in the Compression
and Classification Group of the Information
Systems Lab under the supervision of Robert
M. Gray. I received my Ph.D. in EE from Telecom
Paris (National Superior School of Telecommunications in Paris, France)
in 1997, my M.S. in EE from the same school in 1994 and a B.Sc. in Physics
from the University of Montreal,
Quebec, in 1992.
