Retired Adm. Gary Roughead, former chief of naval operations and current trustee of the Johns Hopkins University, has been selected as chair of the Johns Hopkins Applied Physics Laboratory’s (APL) Board of Managers. Roughead served as the Navy’s top officer from 2007 to 2011, and led efforts to stabilize and accelerate ship and aircraft procurement plans, strengthen the Navy’s capability and capacity in ballistic missile defense and unmanned air and underwater systems, and increase the Navy’s focus on cybersecurity and information assurance. During his naval career, he held six operational commands and is one of only two officers in U.S. Navy history to have commanded fleets in both the Pacific and the Atlantic. He joined APL’s Board of Managers in 2015.
Following his military service, Roughead has continued to make strong contributions to national security. He is the Robert and Marion Oster Distinguished Military Fellow at the Hoover Institution at Stanford University, and chaired the National Academies of Sciences, Engineering, and Medicine Naval Studies Board. He also serves on several corporate boards, including Northrop Grumman.
“Throughout my career, I saw firsthand the difference APL makes for our nation,” said Roughead. “The Lab’s amazing people are keenly focused on our warfighters’ mission, and bring extraordinary technical depth and independent analysis to some of the most consequential challenges facing our military and our country. Together, we will work to ensure this extraordinary national resource remains ready to meet the challenges of today, and those still over the horizon.”
“We are extremely pleased to welcome Adm. Roughead as chair of our Board of Managers. Gary’s distinguished record of forward-thinking, principled leadership and his extraordinary experience will be invaluable as APL continues to deliver capabilities that strengthen our nation’s security,” said APL Director David Van Wie.
Roughead succeeds Ms. Heather Miller, who served as Board chair for the past five years.
Miller’s Leadership Strengthened APL’s Mission
Miller joined APL’s Board in 2013, becoming chair in 2021, and brought decades of experience in finance, government, and the nonprofit sector to the organization. She previously served on the White House Commission on Enhancing National Cybersecurity and as a congressionally appointed commissioner on the Financial Crisis Inquiry Commission. She held senior leadership roles on Wall Street before serving as the founding chairman and CEO of the Nevada Cancer Institute, and also serves as a trustee for Johns Hopkins, her alma mater.
“We are deeply appreciative of Heather’s exceptional leadership, expertise, and service on APL’s Board of Managers over the past 13 years,” said Van Wie. “Her strategic insights and steady guidance, particularly as chair, have positioned the Laboratory for continued success and impact. Heather cultivated new collaborations between the Laboratory and other university divisions, and she consistently encouraged APL leaders and staff to boldly explore emerging technologies, strategic opportunities, and evolving national security challenges.”
During Miller’s tenure as chair, the Laboratory advanced critical capabilities in ballistic missile defense, cyber resilience, hypersonics, undersea warfare, human–robot teaming, and space exploration, while accelerating innovation in artificial intelligence, assured autonomy, biomanufacturing, and next-generation materials.
Miller guided the Laboratory through major capital and infrastructure initiatives, and provided insights during the COVID epidemic that helped APL navigate unprecedented operational challenges. Her focus on the future technical leadership of the nation positioned the Laboratory to tackle evolving challenges, and she championed an enhanced pathway for Johns Hopkins undergraduates to gain experience as APL interns while exploring potential careers. Miller, a member of the Laboratory’s Principal Professional Staff, also provided critical counsel and leadership during the 2025 transition from Ralph Semmel to Van Wie as APL’s director.
Board Welcomes Two New Members as Hon. Stephen Hadley Concludes Term
Retired Army Lt. Gen. Michael Fenzel and the Honorable Christopher Scolese have joined the Board, bringing decades of national security leadership and technical expertise.
Lt. Gen. Fenzel most recently served as the U.S. security coordinator for Israel and the Palestinian Authority. His previous leadership roles during 36 years of service in the Army include vice director for strategy, plans, and policy of the Joint Staff; senior military advisor to the special representative for Afghanistan reconciliation at the U.S. Department of State; chief of staff of the 82nd Airborne Division; and multiple brigade- and battalion-level commands, including multiple combat deployments. He also serves as a trustee of Johns Hopkins, of which he is an alumnus.
Dr. Scolese served as director of the National Reconnaissance Office (NRO) from 2019 until 2026. From 1987 until 2019, he held numerous leadership roles at NASA, including acting administrator in 2009 and director of Goddard Space Flight Center from 2012 until 2019, when he retired to lead NRO. His service to the nation began in 1978 as a naval officer, supporting the Naval Nuclear Propulsion Program for the Navy and the Department of Energy.
The Honorable Stephen Hadley, who has dedicated his career to public service and national security, concluded his service on the Board on June 30. Hadley served as national security advisor from 2005 to 2009 and as assistant to the president and deputy national security advisor from 2001 to 2005. Throughout his 15 years on APL’s Board of Managers, he contributed his extensive expertise in national security strategy and policy to help the Laboratory deliver impact to critical missions and advance science and technology in the national interest.
