The FIA has appointed Dr Ian Roberts as Formula 1 medical rescue coordinator, after deciding not to renew Gary Hartstein's contract at the end of 2012.
Roberts was previously chief medical officer for Silverstone and the British Grand Prix.
An FIA statement said that Dr Roberts would report to Professor Jean-Charles Piette, F1's permanent FIA medical delegate.
"While Professor Piette will oversee emergency operations from race control, Dr Roberts will deploy to the track," said the statement. "His primary role there is to supervise the response of the local medical team."
Hartstein's departure had caused concern among F1 drivers, but he welcomed Roberts' appointment.
"Congratulations Ian," Hartstein wrote on his Twitter account. "Would certainly have been on my shortlist. Really good doctor, skilled leader, great guy. Lots of luck and have a great time.
"Fitting on the eve of Sid [Watkins]'s memorial that someone representing the best of British motorsports medicine be named."
