1999 : graduated from Ecole Polytechnique de Paris, major in fluid dynamics
2001 : graduated from Supaéro (specialized graduate program following the Ecole Polytechnique degree, main subject : aerodynamics), and exchange student in the aeronautics department of Imperial College of London
2000 : 5 months training period in the aero research department > Peugeot
2001-2002 : aerodynamicist > Prost (F1)
2002-2004 : CFD aerodynamicist > Ferrari (F1)
2004-2007 : aerodynamics project leader > Ferrari (F1)

Quite an important man in Ferrari looking at what is stated but I think that there would be a replacement sooner or later. Tombazis is the leading aerodynamics man, so I don't know exactly what his role was.
