Oklo makes board, management changes

By ExchangeMonitor

Santa Clara, Calif.-based Oklo made several personnel changes in key management positions and to its board of directors last week.

Oklo appointed four new directors on April 14. The board members are David Christian, David Park, Derek Kan and Mark Peters. The appointments were made effective April 10, according to Oklo’s press release.

As we begin to build a wide range of facilities required to achieve our ambitious goal of jumpstarting the advanced nuclear energy sector in the United States and around the world, we are excited to lean on the decades of experience that they bring to our board,” Oklo co-founder and CEO Jacob DeWitte said.

Peters, the president and CEO at MITRE, held high-level positions at several Department of Energy national laboratories, including serving as director of Idaho National Laboratory (INL) from 2015 to 2020.

After leading INL for five years, Peters became the executive vice president for national laboratory management and operations at Battelle. He served in that role from 2020 to 2024, prior to joining MITRE in August 2024.

Oklo has moved Michael Thompson from its board to serve as its lead independent director. In Thompson’s new role, he will help the board provide independent oversight for its management team, DeWitte said.

Additionally, the company announced plans to transition Pat Schwieger, the current chief technology officer, to a technical adviser role in the coming weeks. DeWitte said Schweiger’s change comes as part of Oklo’s efforts “to update its management structure to reflect its focus on building business units tackling powerhouse deployment, fuel fabrication, fuel recycling, and radioisotope production.”
