Pentagon CIO announces new appointments

Pentagon Chief Information Officer Kirsten Davies announced several new additions to her team Friday as she pushes forward with digital transformation efforts at the Defense Department.

Before taking the helm as CIO in December, Davies suggested that she intended to “embed the building blocks of AI” and support U.S. military efforts to achieve “data supremacy” and “decision dominance” over adversaries.

A DOD CIO social media post on April 10 stated that the office is “driving to prepare networks, data infrastructure and transport capabilities” to meet Defense Secretary Pete Hegseth’s vision and direction for modernization.

Davies announced that Ryan McArthur will serve as special advisor to the CIO for capability development and operational excellence.

“In this role he will provide critical counsel on emerging technologies and guide our most complex technical initiatives as we transform the Cyber and IT portfolio to support,” according to a post on X from the DOD CIO’s account.

“We have a real opportunity to fundamentally modernize how we approach Cloud, Cyber, and IT moving faster, integrating smarter, and ensuring our capabilities keep pace with the demands of today’s environment,” McArthur wrote in a post on LinkedIn.

McArthur recently held the role of chief technology officer for global public sector at Zscaler. Prior to that, he was an executive program manager at the Defense Information Systems Agency for the department’s $9 billion enterprise Joint Warfighting Cloud Capability (JWCC) program. He previously served as a technical adviser in the office of the deputy CIO for information enterprise and as IT strategy manager at Headquarters Marine Corps. He also held tactical network and communication roles for the Army, according to his LinkedIn profile.

Davies named David Vaughn as technical advisor for data infrastructure, tapping him to provide expertise on data and AI infrastructure initiatives.

The CIO’s social media post described Vaughn as “a decorated cybersecurity executive and U.S. Army Chief Warrant Officer 4 (Cyber) whose nearly three-decade career spans operational cyber warfare, intelligence, and enterprise risk management across the public and private sector.”

He previously worked as a senior cloud security advisor for DISA’s Housing and Compute Center, according to his LinkedIn profile.

In a post on LinkedIn, Vaughn said his new position is “a role that carries tremendous responsibility and one I do not take lightly.”

Kayla Huthoefer Nelson will serve as the CIO office’s new chief of staff, Davies announced. In that role, she will “support executive decision-making, organizational coordination, and leadership priorities” across the department’s “information, technology, and digital modernization enterprise, specifically overseeing the operational tempo and strategic management of the OCIO.”

Huthoefer Nelson “brings significant expertise from the intersection of government, the Defense Industrial Base, and venture-backed defense technology,” the social media post added.

“The work ahead is urgent and consequential: eliminating inefficient spending, reducing technical debt, accelerating modernization, strengthening cybersecurity, promoting commercial-first innovation, expanding partnerships and workforce development, and unleashing AI and data technologies from the core to the edge across the Joint Force,” Huthoefer Nelson wrote on LinkedIn.

She previously held roles as senior defense advisor for the Colorado Aerospace and Defense Economic Council, director for strategic capture and disruptive growth at Clarity, and director for strategic capture at BAE Systems, among others, according to her LinkedIn profile.

Vishal Aswani, who previously served as the DOD CIO’s chief of staff, will step into a new role as special advisor for transformation “amidst our large-scale organizational change and business process re-engineering efforts that are fundamental to building a more agile and effective OCIO for the future,” the office stated in a social media post.

Prior to serving as chief of staff, Aswani held cyber roles with the CIO’s office and the Navy, according to his LinkedIn profile.

Meanwhile, Marci McCarthy has been appointed as director of external engagements, where she’ll be responsible for shaping the office’s strategic communications and leading its engagement with industry, international allies and other key partners “to build the ecosystem of innovation required to support the goals and vision” of Hegseth.

She previously served as director of public affairs at the Cybersecurity and Infrastructure Security Agency (CISA).

In a post on LinkedIn, McCarthy wrote that she’s ready to “get to work advancing the Arsenal of Freedom and building strong partnerships across industry and our allies.”
