The President of competition and operations for IndyCar, Derrick Walker is to resign from his position at the end of this season. Walker is to pursue other opportunities according to Mark Miles, the Chief Executive of the series.
Walker began his career in racing in 1970 as a Chief Mechanic for the Brabham Formula One team owned by Bernie Ecclestone. He took over the position in IndyCar in May 2013.
