Nancy Reid Gibbs is an author, speaker, presidential historian and commentator on politics and values in the United States. She joined TIME magazine as a part-time fact checker in 1983 and rose to become its Editor-in-Chief in 2013, the first woman to hold the position. She was one of the most published writers in the history of the magazine and wrote more cover stories than anyone else at TIME. Under her leadership, TIME’s digital audience expanded from 25 to 55 million and its video streams to more than one billion a year.

She remained at TIME as Editor-in-Chief and Editorial Director until September 2017, directing its news and feature coverage for more than 65 million readers worldwide. She was also a consultant to CBS News and an essayist for the News Hour on PBS, and co-authored with Michael Duffy two best-selling presidential histories: The President’s Club: Inside the World’s Most Exclusive Fraternity (2012) and The Preacher and the Presidents: Billy Graham in the White House (2007).

She has interviewed five U.S. presidents and multiple other world leaders, and lectures often on the American presidency, including at the Bush, Reagan, Carter, Johnson and Truman libraries.

In September 2017, while remaining an Editor at Large at TIME, she stepped down from her post as Editor in Chief and became Visiting Edward R. Murrow Professor of Press, Politics and Public Policy at Harvard University’s Kennedy School. In 2019, she was additionally named Lombard Director of the Kennedy School’s Shorenstein Center in Media, Politics and Public Policy.

The press release welcoming her to Harvard described her as “an extremely thoughtful and respected voice on issues of politics, values, and society” and noted that “her extensive knowledge and insights will help illuminate research and discussions at the school about the role of journalism in democracies and in the digital age.” She is still an Editor at Large at Time.

She graduated from Yale summa cum laude with honors in history and has a degree in politics and philosophy from Oxford, where she was a Marshall scholar.

When Andrew Selee became president of the Migration Policy Institute (MPI) in 2018, his predecessor noted that Selee “has a distinguished track record not only as a serious policy scholar but a leader who has thought deeply about think tank strategy and administration.”

Those qualities are especially apt for the Migration Policy Institute, a nonpartisan body working with a wide range of stakeholders on immigration and integration policies, with a focus on fact-based research, dialogue, and the development of new ideas in response to complex policy questions.

MPI has published more than 500 research reports and books, provided testimony before the U.S. Congress and parliamentary bodies in more than a dozen countries, advised numerous governments and civil-society organizations, and organized countless public and private conferences.

Dr. Selee’s own research focuses on migration globally and especially on immigration policies in the United States, Latin America and the Caribbean. He has written extensively on U.S.-Mexico relations, Mexican politics, U.S. immigration policy, organized crime, and democracy in Latin America. His most recent book is Vanishing Frontiers: The Forces Driving Mexico and the United States Together (PublicAffairs, 2018).

Before joining MPI, Dr. Selee spent 17 years at the Wilson Center in Washington, D.C., where he founded the Center’s Mexico Institute and served for three years as executive vice-president, managing the Center’s day-to-day operations and global research agenda for its 135-member staff. Previously, he was a professional staffer at the U.S. Congress and worked on YMCA programs for migrant youth in Tijuana, Mexico.

His public opinion articles have appeared in The Wall Street Journal, Washington Post, Dallas Morning News, Houston Chronicle, Americas Quarterly, and other media, and he writes a biweekly column for the Mexican newspaper El Universal. He is often interviewed in the press, including PBS, NBC, CBS, Fox News, NPR, BBC, New York Times, Washington Post, Wall Street Journal, and The Economist.

He holds a PhD in policy studies from the University of Maryland; an MA in Latin American studies from the University of California, San Diego; a BA, Phi Beta Kappa, from Washington University in St. Louis; and a certificate in strategic perspectives on nonprofit management from Harvard Business School. He was an Andrew Carnegie Fellow in 2017-2018, is an adjunct professor at Georgetown University, and has previously taught at Johns Hopkins and George Washington universities and El Colegio de México.

Nathaniel Keohane has been called “one of the most original thinkers and inspirational leaders in the climate community.” He is president of the Center for Climate and Energy Solutions (C2ES), an independent, non-partisan, nonprofit organization known nationally and internationally for its effectiveness in bringing stakeholders together to develop innovative, effective and durable climate policies. Keohane himself is known for his optimism about the role markets can play in resolving global warming.

Before becoming president of C2ES, Keohane was Senior Vice President for Climate at the Environmental Defense Fund. He served in the Obama administration as special assistant to the president for energy and environment in the National Economic Council and the Domestic Policy Council, developing and coordinating policy on a wide range of energy and environmental matters. He has also been an associate professor in the Yale School of Management and an adjunct professor at New York University.

He holds a B.A. in Economics from Yale and a Ph.D. in Political Economy and Government from Harvard University. He was an accomplished rower at Yale and held the Club Singles course record at the Head of the Charles for 20 years after it was set in 1997.
