From 2011-2014 she served on the Foreign Affairs Policy Board, which advises the Secretary of State quarterly. Her work on security sector and police reform in violent democracies has led her to serve on the UN Security Sector Reform Advisory Group and as a fellow with the Halifax International Security Forum.

Previously, Dr. Kleinfeld was founding CEO of the Truman National Security Project, for which she was named one of the 40 under 40 top political leaders in the United States by Time Magazine. She has published three books and appears frequently in the media. Her last book on reducing violence in polarized democracies became a TED talk that has been translated into 17 languages and seen over a million times.  She holds a B.A. from Yale University and an M. Phil and D. Phil from Oxford, which she attended as a Rhodes Scholar.

Dr. Wintemute is Distinguished Professor of Emergency Medicine and Baker–Teret Chair in Violence Prevention at the University of California, Davis. He is the founding director of the Centers for Violence Prevention there, which comprise the Violence Prevention Research Program and the California Firearm Violence Research Center—the nation’s first publicly funded center for research in this field. He was among the first to study and act on firearm violence as a public health problem. His current research focuses on firearm violence risk factors at the individual and social levels and on interventions to prevent violence, with an emphasis on political violence.

Trained initially as a biologist at Yale University, Dr. Wintemute attended medical school and residency at UC Davis and studied epidemiology and injury prevention at The Johns Hopkins University. He is a member of the National Academy of Medicine, and he practices and teaches emergency medicine at UC Davis Medical Center, a Level I trauma center.
