Twitter has named Bret Taylor, former chief technology officer at Facebook and currently CEO of productivity software maker Quip, to its board.

Taylor’s appointment further reshapes the Twitter board following the departure in May of Peter Chernin and tech investor Peter Currie, who were replaced by PepsiCo CFO Hugh Johnston and Internet entrepreneur Martha Lane Fox, and after Twitter named BET Chairman and CEO Debra Lee to its board in May. The company had been criticized for a lack of diversity on its board, and Twitter executive chairman and former Google exec Omid Kordestani has pledged the board would take steps to rectify the situation.

Twitter is infusing new blood into its board as the company continues to face challenges growing its user base and revenue amid turnover among its executive ranks, along with heightened speculation that Twitter may be an acquisition target. Co-founder Jack Dorsey, who returned as the company’s permanent CEO last October, is focusing on video as a key segment to drive Twitter; the company also is delving into virtual reality and augmented reality with the recent hiring of former Apple designer Alessandro Sabatelli.

Taylor, 35, became CTO of Facebook in 2009, after it acquired FriendFeed, the social network he co-founded in 2007. He worked at Facebook — where he helped create the social service’s iconic “like” button — until 2012, and has been CEO of Quip since September 2012.

Taylor, who also serves on the board of directors of Taser International, also previously was a group product manager at Google, where he is credited with co-creating Google Maps and starting Google’s Developer product group. He holds a bachelor’s degree in science and a master’s degree in computer science from Stanford University.

“Bret brings to our board a great mind for consumer products and technologies that will be invaluable to the company as we execute our plans for 2016 and beyond,” Kordestani said in announcing the appointment. “His skills also complement those of our other recent Board additions, who bring expertise in finance, media, and entrepreneurship.”

“Twitter is the fastest way to find out what’s happening, and beneath its simplicity lies a very sophisticated set of technology,” Taylor said in a statement. “I hope to bring my knowledge and experiences to bear to help Jack and the board push Twitter and its services forward.”
