Title: MAIN POINTS IN MY CAREER
Author(s): J.-P.Badiali

I started my scientific life with theoretical and experimental works concerning the dielectric relaxation of ionic solutions. After that a large part of my scientific life will be devoted to the theory of charged and polar systems. The investigations on ionic systems suggest to study liquid metals as another example of charged medium. When a metal and an ionic solution are put together they form an electrochemical interface. In the early 1980's we proposed the first calculations showing explicitly the role of electronic distribution in the electric properties of an ideally polarizable electrode. In parallel, the effect of the image potential on the structure of the interface has been investigated and some exact results have been obtained by summation of diagrammatic expansions.
