The Pentagon’s deputy chief information officer will retire at the end of June and will be replaced by the Intelligence Community’s top technology officer, the department said Monday.

Essye Miller previously served as CIO in an acting capacity before Dana Deasy, the current CIO, took over the role in May 2018.

“I want to wish Essye Miller well in her upcoming retirement and thank her for 35 years of federal service to our nation,” Deasy said in a statement. “Essye has been a trusted adviser to me, especially as I came onboard the DoD. Essye is without a doubt an inspiration to many and her dedication to the mission and leadership style will be missed throughout the department.”

John Sherman, the IC CIO, will take over Miller and leave his role overseeing the CIA, FBI and other intelligence departments’ IT modernization efforts.

“John will bring a breadth of experience to the organization and I look forward to working with him as we continue to implement the digital modernization strategy across the DoD,” Deasy said. 

During her time as deputy CIO, Miller initiated the Joint Enterprise Defense Infrastructure cloud program, oversaw the Joint Regional Security Stacks program and has recently led much of the department’s push for teleworking technologies during the ongoing coronavirus pandemic.
