Mark Gilbertson, one of the top supervisors at the Department of Energy’s nuclear cleanup branch, is calling it a career at the end of the month, the agency said Tuesday.
Gilbertson, currently associate principal deputy assistant secretary for regulatory and policy affairs, is retiring after 25 years at the DOE Office of Environmental Management (EM) and holding many key jobs, Acting Assistant Secretary for Environmental Management William “Ike” White said in a recent “Dear Colleague” email.
Gilbertson has more than 38 years of public and private sector experience, White said. “Mark has been a cornerstone of the EM leadership team and key to many of EM’s successes over the years,” White went on to say in an EM press release on Tuesday.
Over the years, Gilbertson has served stints as EM’s No. 2 person, the principal deputy assistant secretary, as well as the National Laboratory Officer, and in various deputy assistant secretary posts such as site restoration, program and site support as well as engineering and technology. Prior to Environmental Management, Gilbertson held key management jobs in other DOE offices such as Legacy Management and the former Environment, Safety and Health Office. He also spent four years at the Environmental Protection Agency and worked as an engineering consultant in the private sector.
The DOE cleanup office simultaneously announced Jay Mullis, manager of the Oak Ridge Site field office in Tennessee, will take over from Gilbertson on an acting basis effective Nov. 1. In addition, Mullis’s deputy manager at Oak Ridge, Laura Wilkerson will become acting manager of that office.
Mullis has 30 years of federal service and has supervised the Oak Ridge office since November 2017, according to his online bio. In that role, Mullis has responsibility for an annual budget of more than $650 million, DOE said. Wilkerson has 30 years of experience with DOE and has managed various projects and programs, the agency said. As deputy manager she oversees much of the day-to-day remediation issues at Oak Ridge.
