Sandia National Labs has appointed Marianne Walck, a geophysicist, to be vice president of the California laboratory, Sandia said on Thursday.

As part of this appointment, Walck will oversee the Energy and Climate program at the facility. She replaces Steve Rottler, who was appointed deputy director and executive vice president for National Security Programs.

Previously, Walck served as director of the lab's Geoscience, Climate and Consequence Effects Center.

“I am pleased to welcome Marianne to Sandia’s executive leadership team,” Paul Hommert, Sandia's president and labs director, said. “She brings a deep and accomplished background in energy, as well as demonstrated success in leading large organizations. These skills and knowledge make her well-suited to leading both our California organization and our energy programs.”

Walck holds a doctorate in geophysics from the California Institute of Technology; she originally joined the laboratory in 1984. Her research has focused on seismic activity related to energy sources beneath the earth's surface and has helped develop tools to monitor microseismic activity, including hydraulic fracturing and its effect on the earth's sub-surface.

“I am honored and excited to have the opportunity to lead the diverse activities at Sandia’s California laboratory and the Energy and Climate program,” Walck said after her appointment.
