TELL, CHARLES was born on May 9, 1937 in Chicago, Illinois, United States.
Born in Brussels on May 9, 1937, Charles J. Joachain obtained his Ph.D. in Physics in 1963 at the Université Libre de Bruxelles (Free University of Brussels).
From 1964 to 1965 he was a Postdoctoral Fellow of the Belgian American Educational Foundation at the University of California, Berkeley and the Lawrence Berkeley Laboratory, and from 1965 to 1966 a Research Physicist at these institutions. At the Université Libre de Bruxelles he was appointed chargé de cours associé in 1965, chargé de cours in 1968, professeur extraordinaire in 1971 and professeur ordinaire in 1978. He was chairman of the Department of Physics in 1980 and 1981.
He was also appointed professor at the Université Catholique de Louvain in 1984. In 2002, he became professeur ordinaire émérite (Emeritus Professor) at the Université Libre de Bruxelles and professeur honoraire at the Université Catholique de Louvain. Professor Joachain has been a visiting professor in several universities and laboratories in Europe and the United States, in particular at the University of California, Berkeley and the Lawrence Berkeley Laboratory, the Université Pierre et Marie Curie (Paris VI), the University of Rome “La Sapienza” and the Max Planck Institute for Quantum Optics in Garching.
The research activities of Professor Joachain concern two areas of theoretical physics: 1) Quantum collision theory: electron and positron collisions with atomic systems, atom-atom collisions, nuclear reactions, high-energy hadron collisions with nuclei. 2) High-intensity laser-atom interactions: multiphoton ionization, harmonic generation, laser-assisted atomic collisions, attophysics, relativistic effects in laser-atom interactions.
He is a member of the Académie Royale des Sciences, des Lettres et des Beaux-Arts de Belgique, of the Academia Europaea and of the European Academy of Sciences.
