Wired reports:

Darpa director Regina Dugan will soon be stepping down from her position atop the Pentagon’s premiere research shop to take a job with Google. Dugan, whose controversial tenure at the agency lasted just under three years, was “offered and accepted at senior executive position” with the internet giant, according to Darpa spokesman Eric Mazzacone. She felt she couldn’t say no to such an “innovative company,” he adds. […]

The Pentagon’s Office of Inspector General (OIG) is also actively investigating hundreds of thousands of dollars’ worth of contracts that Darpa gave out to RedX Defense — a bomb-detection firm that Dugan co-founded, and still partially owns. A separate audit is examining a sample of the 2,000 other research contracts Darpa has signed during Dugan’s tenure, to “determine the adequacy of Darpa’s selection, award, and administration of contracts and grants,” according to a military memorandum.

Results of the inspector general’s work haven’t been released. And the work had “no impact” on Dugan’s decision, according to her spokesman, Mazzacone. “The only reason” she decided to leave the Pentagon was the allure of working at Google.
