Dr. Jacques J. Vidal was born in Liege, Belgium.
He obtained an Electrical Engineering
degree from the University of Liege in 1954,
After a military term ending as a Reserve First Lieuteant
in the Belgian Air Force,
he became a Lecturer at the University of Liege,
and in the same period,
earned a Nuclear Engineering Certificate in 1958
from the INSTN in Saclay, France and, in 1961, a Doctorate
from the University of Paris.
He left Belgium for the United States in 1963
to join the faculty of the School of Engineering at
the University of California, Los Angeles.
He is now Emeritus Professor in the
UCLA Computer Science Department
of which he was a founding member.
Although officially in retirement, he continues to work with his
graduate students and at times to teach
his signature class.
Neural Network and Soft Computation (CS267A-B).
This course has been consistently well received by students and,
through multiples revisions and occasional name changes,
was offered yearly for nearly thirty years.
Since the release of the Mathematica software in the early nineties,
the course format evolved toward computer demonstrations in the classroom.
The courseware written for this class
became a continually expanding collection of
Some of these notebooks have also been available on the
mathsource database at
Long interested in the mysteries of the Brain, Vidal
spend a sabbatical year in 1970 at
the UCLA Brain Research Institute to study the mammaliam vestibular system
and joined a research group headed by Professor Jose Segundo.
Subsequently he was elected a permanent member of the Institute.
During the seventies, Vidal coined the expression
Brain Computer Interface
for his current research project, a part of a large, government sponsored
futuristic research in biocybernetics and human-machine interaction.
The name is now firmly entrenched into the lexicon of biocybernetics research.
One of the results was the first successful attempt to include
brain signals into human-computer communication,
The goal of providing a non invasive communication channel
into the human brain remains a contemporary challenge.
A number of laboratories in the US and
abroad are currently involved in related projects.
His dominant research interests, still brain-related
albeit sometime indirectly, have revolved around "Soft Computing"
(Neural Networks, Fuzzy Systems
Recently, and through his long term association with a research group at
the University of Paris
headed by Professor Alain-jacques Valleron, Vidal has started to explore
the application of functional modeling in statistics and, in particular,
to the prediction of outbreak of disease,
a concern given a new importance by the emergence
