gabriel strickerGabriel Stricker, who led marketing and communications for Twitter before stepping down in July, has returned to Google to head policy and communications for its fiber-optic Internet push.

Stricker, whose post is with Google's conglomerate parent Alphabet, earlier led global communications and PA for the search giant before his three years at Twitter.

Google has rolled out high-speed fiber Internet and TV service in cities like Austin, Provo, Kansas City and Atlanta, among others. The Google Fiber unit was moved under Alphabet this year in the company's restructuring.

Stricker said via Twitter that he starts the new post on Jan. 4, 2016, adding he's "thrilled" to guide communications and policy "in its quest to make the Web better and faster for all."

He was Twitter's chief communications officer before leaving amid an overhaul of top management at the microblogging platform this year that included the exit of CEO Dick Costolo.
