Pentagon announces senior appointments to CIO’s office

The Pentagon formally announced on Wednesday that five officials received new appointments within the Office of the Chief Information Officer to help manage the department’s sprawling technology landscape. 

The personnel will help fill out the senior leadership team for Defense Department CIO Kirsten Davies, who was sworn into her role in December. 

"Their collective expertise in cybersecurity, defense innovation, and enterprise-level strategy is exactly what we need to accelerate our mission,” she said in a statement. “Their leadership will drive transformation across the entire CIO enterprise, cutting through bureaucracy to deliver secure, cutting-edge technology to our warfighters.”

Kayla Huthoefer Nelson was named OCIO’s new chief of staff, where she will be responsible for managing the office’s operations. The department noted that she has held senior positions at BAE Systems and Clarity Innovations, and previously served as a defense advisor to the Colorado Aerospace and Defense Economic Council.

DOD said Nelson will be taking over the position held by Vishal Aswani, who is transitioning to a new temporary role as special advisor for transformation within the office, where he “will guide the OCIO’s large-scale organizational change and business process re-engineering efforts.”

Marci McCarthy, who previously served as the Cybersecurity and Infrastructure Security Agency’s director of public affairs, was also appointed as the DOD CIO office’s director of external engagements. 

OCIO also announced the appointment of two officials who will have a more targeted focus on leveraging new technologies, such as artificial intelligence. 

Ryan McArthur, a retired Army signal chief warrant officer, is joining the office as the special advisor to the CIO for capability development and operational excellence. DOD said he previously led the Defense Information Systems Agency’s Joint Warfighting Cloud Capability program at the Defense Information Systems Agency — a roughly $9 billion contract to enhance and streamline the department’s cloud capabilities. 

In his new role, the Pentagon said McArthur “will provide critical counsel on emerging technologies and guide the Department’s most complex technical initiatives.”

Finally, DOD said that David Vaughn has been named OCIO’s technical advisor for data infrastructure, where he will provide “expertise on data and AI initiatives.” Vaughn has served for nearly three decades in the U.S. Army Reserves, attaining the title of chief warrant officer 4 in its cyber branch. He also worked in the private sector at Equinix and Cyber Defense Technologies, and held senior advisory roles at the 75th Innovation Command and with DISA.

“We are accelerating our work to bring innovative technologies to the fight, support the IT requirements of AI, and engage meaningfully with our allies, partners, and the DIB,” Davies said in a statement. “This team's mission is to ensure America’s fighting force has the decisive digital advantage on any battlefield, and they will make that a reality."

Davies first shared the appointments in a series of X posts on Friday, prior to the department’s Wednesday announcement.
