EPA's Lisa Jackson joins Apple

Former Environmental Protection Agency Administrator Lisa Jackson is joining Apple.

Apple CEO Tim Cook said on May 28 that Jackson, who stepped down from the EPA in February after four years with the Obama Administration, will be heading the Cupertino, Calif.-based technology company's environmental efforts. Cook made the announcement at the D11 Conference during an on-stage interview with technology journalists Walt Mossberg and Kara Swisher. "She’s going to be coordinating a lot of this activity across the company," Cook said of Jackson.

Jackson waged several high-profile regulatory battles while at EPA, and also drew congressional attention for her use of "alias" e-mail accounts to conduct government business.

Apple has not yet announced when Jackson will formally start in her new role.
