Professor Chanfreau was born and raised in Paris France in 1968 and did his undergraduate studies in Lyon, France. He graduated in 1989, and then spent a year preparing for the highest competitive examination for teachers in France (Agregation), which he obtained in 1990. After a one-year hiatus in the army for his military service in the mountain infantry in the French alps, he started his graduate studies in 1991 at the Pasteur Institute in Paris to work on intron ribozymes with Dr Alain Jacquier. He graduated in 1995 and decided to go to San Francisco for his postdoctoral studies, to work with Christine Guthrie and learn yeast genetics. He went back to Paris in 1997 after obtaining a position of research scientist at the CNRS, but decided to go back to the US in 1999, when he joined the ranks of the faculty at UCLA. He married his wife Catherine in 2001, and they are raising two sons, Antoine, born in 2003 and Jeremy, born in 2005. Aside from research, teaching and raising his kids, Professor Chanfreau enjoys going scuba diving and making movies out of his dives. His favorite diving destinations are the "golden triangle" Galapagos-Cocos-Malpelo Island in the Eastern Pacific Ocean. His movies have been projected at several underwater film festivals.
