JeanChristophe Yoccoz was a French mathematician. He was awarded a Fields Medal in 1994, for his work on dynamical systems.
1. Biography
Yoccoz attended the Lycee LouisleGrand, during which time he was a silver medalist at the 1973 International Mathematical Olympiad and a gold medalist in 1974. He entered the Ecole Normale Superieure in 1975, and completed an agregation in mathematics in 1977. After completing military service in Brazil, he completed his Ph.D. under Michael Herman in 1985 at Centre de mathematiques LaurentSchwartz, which is a research unit jointly operated by the French National Center for Scientific Research CNRS and Ecole polytechnique. He took up a position at the University of ParisSud in 1987, and became a professor at the College de France in 1997, where he remained until his death. He was a member of Bourbaki.

He joined the French Academy of Sciences and Brazilian Academy of Sciences in 1994, became a chevalier in the French Legion of Honor in 1995, and was awarded the Grand Cross of the Brazilian National Order of Scientific Merit in 1998.
2. Mathematical work
Yoccozs worked on the theory of dynamical systems, his contributions include advances to KAM theory, and the introduction of the method of Yoccoz puzzles, a combinatorial technique which proved useful to the study of Julia sets.
