Microsoft Corp. executive Dee Templeton has joined OpenAI’s board as a nonvoting observer, according to a person familiar with the matter, as part of a broader boardroom overhaul following the brief ouster of the startup’s chief executive officer.

Templeton has worked at Microsoft for more than 25 years and is the company’s vice president for technology and research partnerships and operations, according to her LinkedIn profile. She has already begun attending board meetings, according to the person, who spoke on condition of anonymity to discuss private matters. OpenAI and Microsoft declined to comment.
