Full professor at the National Institute of Applied
Sciences of Lyon (INSA-Lyon)
Wirless network architecture and
algorithms for telecommunications.
UBEDA STEPHANE is a full professor
at the National Institute of Applied Sciences of Lyon in the
Telecommunications department. He is also the director of
the Center for Innovations in Telecommunication and Services
integration (CITI Lab) which is the research lab associated to
the department. Last, he is also the head of the INRIA Project
named ARES for Architecture of Networks of Services. The
ARES project is dedicated to Ambient Networks and associated services.
The research team of the CITI Lab is composed of 14 permanent peoples
and 10 PhD students and 3 administrative peoples.
After a PhD in computer sciences at
the Ecole Normale Supérieure de Lyon in 1993, STEPHANE
UBEDA was assistant professor at the Swiss Federal Institute of
Technology in Lausanne (EPFL) in the computer sciences department. At
the EPFL, STEPHANE UBEDA was member of the Theoretical Computer
Sciences Lab directed by the Professor Giovani Coray. During this 2
years period, STEPHANE UBEDA was working on parallel algorithms and
high performance computing.
In 1995, STEPHANE UBEDA became
associated professor in the Jean-Monnet University and member of
the LIP Lab in the Ecole Normale Supérieure de Lyon. In the
Jean-Monnet University, he was in charge of the creation of a master in
computer sciences. In the LIP Laboratory, STEPHANE UBEDA has created a
research group in algorithms and optimisations for telecommunications
STEPHANE UBEDA obtain a Habilitation
to conduct research in 1997 and became in 2000 full professor at
the INSA of Lyon. In the INSA of Lyon, STEPHANE UBEDA was in charge of
the creation of the research Lab associated to the teaching department.
At the same period, he also launch a new research project in
association with the national research institute in computer sciences
and automata (INRIA). This INRIA project is now created and it is
focused on various aspect of ambient networks (wireless communications,
ad hoc protocols, ambient services).
