— Stanford professor Susan Athey, a former consulting chief economist at Microsoft, will join the U.S. Department of Justice as its top antitrust economist, Bloomberg reported. Athey consulted with Microsoft from 2007 to 2013, where her expertise included big data analytics, antitrust and policy relating to internet search and online advertising. Her regulatory efforts at the tech giant included antitrust investigations against Google.

Athey joins the Justice department as it prepares for a trial against Google and investigates Apple. Bloomberg reported that she is likely to be recused from those cases because of her previous work, which includes serving as an expert in an antitrust suit against Apple.

Athey’s move also comes as the U.S. Federal Trade Commission and other regulators scrutinize Microsoft’s proposed acquisition of video game company Activision Blizzard. Amazon is also facing antitrust investigations in the U.S., U.K., and E.U.

Athey recently resigned from the Expedia board of directors, and announced plans to step down from the board of Seattle pet sitting company Rover in August.
