Williams has announced two more key technical appointments as the team attempts to improve its fortunes in the build-up to 2012 and the departure of Sam Michael.
Jason Somerville will take up the role of Head of Aerodynamics on August 15, while Mark Gillan will Chief Operations Engineer from October 1, and will attend the last few races of the season.
Somerville has been at Williams before. He worked on the BMW Le Mans car and then moved into the F1 team in 1999, becoming joint head of aero. He then joined Toyota and subsequently Renault, as Project Leader Aerodynamics.
Gillan started at McLaren as a vehicle dynamicist in 1998, becoming Principal Operational Aerodynamicist in 2001. He then joined Jaguar as Head of Vehicle Performance and Chief Race and Test Engineer.
He then took up a Professorship at the University of Surrey before moving to Toyota F1 Team as Head of Aerodynamics. He later returned to Surrey as Professor of Vehicle Engineering, but has kept in touch with F1 as an aero consultant.
Frank Williams said: “Williams F1 is looking forward to welcoming Jason and Mark to the team. They bring with them talent, experience and good team skills. We now feel that, together with Mike Coughlan, Jason and Mark can form the right technical leadership to take the team forward as we work our way back to the front of the grid.”

Can’t wait to see Williams challenging at the front again
Sounds like another good hire.
shame they’re only taking on folks now rather than when Sam Michael needed some support.
