The U.S. Department of Energy Office of Environmental Management posted an updated organization chart last month that lists Thomas Mooney as the new chief of staff.
Sources said in December that Mooney, a former U.S. Department of Defense senior manager, was becoming the new chief of staff at the environmental cleanup office although the Energy Department declined to confirm the appointment at the time.
Mooney joins the Energy Department after serving as chief of staff for the Pentagon’s Office of the Chief Management Officer since October 2017 where he helped oversee business operations, including the DoD’s financial plan. Mooney spent most of 2017 as a deputy White House liaison for the Defense Department. Between 2009 and 2017, Mooney was a project lead and analyst at Virginia-based LMI Management Consulting where he worked on strategic planning and communications.
The last permanent chief of staff at the Office of Environmental Management was Darcey Bolin who came to the agency in 2018 from CH2M to work under then DOE Assistant Secretary for Environmental Management Anne Marie White. White resigned in June and Bolin left DOE in July.
The latest management chart, dated Dec. 9, also shows that former Deputy Chief of Staff Joceline Nahigian has left that job to become acting deputy manager for intergovernmental affairs and stakeholder engagement.
AECOM’s former executive vice president and chief legal officer, Carla Christofferson, has been named chief risk officer for DXC Technology, a global information systems and cybersecurity company.
The Northern Virginia-based DXC Technology announced Christofferson’s hiring in a Tuesday press release.
Christofferson will advise DXC President and CEO Mike Salvino on emerging risks. “The management of enterprise risk is a critical function for global companies today,” Salvino said in the press release.
AECOM, the Los Angeles-based infrastructure multinational that is in the process of selling its Energy Department contracting unit, said Nov. 29 it and Christofferson “mutually agreed” she would leave her management post immediately and would exit the company altogether in mid-December.
After joining AECOM in 2015, Christofferson oversaw a legal staff of over 200 people. She also served as managing partner at the O’Melveny & Myers law firm in Los Angeles from 2008 to 2014. During her 22-year tenure at the firm, Christofferson represented industries such as natural gas, oil, and electric power.
