atkinsonCaroline Atkinson, former White House deputy national security adviser for President Obama, has joined Google to head public policy.

She takes a role vacated last year by Rachel Whetstone, who moved to Uber.

Atkinson was NSA for international economic affairs and special assistant to the president. She earlier directed the International Monetary Fund's external relations department and served in the US Treasury Dept., as well.

Google general counsel Kent Walker called her an "internationally respected diplomat and adviser."

Atkinson's global pedigree will be useful as the search giant faces antitrust scrutiny in the European Union.
