[1] At the École Centrale des Arts et Manufactures, Rouet graduated in 1969 with an engineering degree and in 1974 with a doctorate in theoretical physics.
He worked as a postdoc for the academic year 1975–1976 at the Max Planck Institute for Astrophysics (MPA) in Munich and from 1976 to 1978 at CERN.
From 1996 to 2003 he created and developed Quantaflow, a company that designed, manufactured, and sold an innovative system of software and hardware that counted people at places like shopping centers and airports.
The Quantaflow system provided distributed architecture and web services to managers and employees for analysis and certification of customer visits.
[2][4] Rouet is known for his collaborative development in the mid-1970s with Raymond Stora and Carlo Becchi of the BRST formalism[5] (independently done by Igor Tyutin).
