Dr. Duffy has initiated several special projects at the Club, including Voices of Reform (now the independent organization California Forward). These efforts have convened experts and stakeholders in challenging fields to build consensus for solutions and action. Dr. Duffy led the Club to produce its first full-length film, Final Choice, for PBS in 1998, and oversaw the editing and publication of Each a Mighty Voice (Heyday Press, 2004), which placed important speeches at the Club in their historical context.

She led the building search and capital campaign that enabled the Club to purchase 110 The Embarcadero, which will serve as its permanent headquarters and the first time the organization has owned its own home.

Prior to becoming president and CEO of The Commonwealth Club, Dr. Duffy was U.S. deputy assistant secretary of defense and special coordinator for cooperative threat reduction.

Dr. Duffy received her A.B. magna cum laude in 1975 from Occidental College and her M.A. (1977), M.Phil. (1980), and Ph.D. (1991), all in political science, from Columbia University in New York, where she studied at the Harriman Institute. She also holds a Doctor of Humane Letters (honoris causa), awarded by the University of San Francisco in 2006.

Philip Yun’s career has spanned the private and public sectors for the past 40 years, with experience in security affairs, foreign policy, diplomacy, international development, law, business, politics, and philanthropy. He is currently co-president and co-CEO of Commonwealth Club World Affairs of California (CCWA), a leading nonpartisan public forum based in San Francisco.

CCWA is the product of a merger between the World Affairs Council of Northern California, founded in 1947, and The Commonwealth Club of California, established in 1903. Combined, both organizations have been an integral part of the Bay Area’s civic life for over 200 years. CCWA continues to provide a local, regional, and national platform for newsmakers, changemakers, and leaders to discuss and advocate for local and global solutions facing our world while advancing diverse ideas and viewpoints. Its platform includes weekly radio programs and podcasts that are carried by almost 300 radio stations throughout the U.S.

Mr. Yun transitioned to his current position on November 1, 2023, following four years as president and CEO of World Affairs.

Mr. Yun was a presidential appointee at the U.S. Department of State (1994-2001), serving as senior advisor to the assistant secretary of state for East Asian and Pacific affairs. During this time, he also worked as a senior advisor to two U.S. coordinators for North Korea Policy: former Secretary of Defense William J. Perry; and then former Under Secretary of State Wendy Sherman. Mr. Yun was a member of a government working group that managed U.S. policy and negotiations with North Korea under President Clinton and was part of the U.S. delegation that traveled to North Korea with Secretary of State Madeleine Albright in October 2000.

Prior to government service, Mr. Yun practiced law at the firms of Pillsbury Madison & Sutro in San Francisco and Garvey Schubert & Barer in Seattle. He was also a foreign legal consultant at the firm of Shin & Kim in Seoul, Korea.
