Former Ferrari Formula 1 team chief designer Nikolas Tombazis has joined the FIA to become its 'head of single-seater technical matters'.
Tombazis, who was most recently involved in grand prix racing as chief aerodynamicist at Manor until it folded at the beginning of last year, will have core responsibilities in F1, Formula 2 and Formula 3.
He will report to FIA technical director Gilles Simon and work in close co-operation with F1 race director Charlie Whiting.
It is understood Tombazis' role will be to contribute to the long-term strategy of the FIA's main single-seater championships, and help frame sporting and technical regulations.
He will also be involved in discussions with F1 teams and other parties regarding the creation and implementation of new rules.
Tombazis was originally involved in F1 as chief aerodynamicist at Benetton from 1992 until '97, before moving to Ferrari to take a similar role until 2003.
After that he joined McLaren for a two-year spell between 2004 and '06, before returning to Ferrari as chief designer - a role he kept until December 2014.
Following his one-year spell at Manor in 2016/17 he set up his own consultancy, called MAA, and was a visiting professor of aerodynamics for Imperial College London.
