Zubrow is the latest to fall in a high-level shake up at the bank that lost an estimated $5.8 billion in trading blunders, which the bank made public in May.
Zubrow is a top adviser to Chief Executive Officer James Dimon. He confirmed his departure in a memo to employees, The Wall Street Journal reported Saturday.
The bank's head of risk management since 2007, Zubrow is part of a 15-member council that makes the bank's major decisions and will be the fourth out of that inner circle to leave the bank in the wake of the huge losses.
