Tommy Beaudreau, Ambassador Sarah Bianchi, Sir Stephen Lovegrove, and Mari Pangestu Join CGEP as Distinguished Visiting Fellows

The Center on Global Energy Policy (CGEP) at Columbia University’s School of International and Public Affairs (SIPA) welcomes Tommy Beaudreau, former U.S. Deputy Secretary of the Interior; Ambassador Sarah Bianchi, former U.S. Deputy Trade Representative; Sir Stephen Lovegrove, former UK National Security Advisor; and Mari Pangestu, former Minister of Trade and Minister of Tourism and Creative Economy of the Republic of Indonesia, as the latest additions to its Distinguished Visiting Fellows program.

The Distinguished Visiting Fellows program brings veterans from the public and private sectors into the Columbia University community. Distinguished Visiting Fellows serve as adjunct research scholars, contribute to articles and op-eds published through CGEP, engage in public events at Columbia, and work with student and faculty groups across campus.

“This year’s cohort again underscores the Center’s commitment to bringing energy and climate leaders with policy experience at the highest levels and global perspectives into the Columbia community to share their expertise and experiences with Columbia students, our scholars, and the Columbia community,” said Jason Bordoff, founding director of CGEP. “With decades of real-world experience, Tommy, Sarah, Stephen, and Mari offer invaluable perspectives across a wide spectrum of issues, including energy security, trade, geopolitics, climate policy, clean energy deployment, and sustainable development. We are honored to have them contribute to our mission of delivering education and timely and impactful policy research.”

Tommy Beaudreau, Co-Chair of WilmerHale’s Energy, Environment, and Natural Resources Practice, previously served as Deputy Secretary of the Interior. In this role, he oversaw energy development on public lands, water infrastructure, drought response in the American West, infrastructure permitting, critical minerals development, and the implementation of the Bipartisan Infrastructure Law and Inflation Reduction Act.

“I am excited to re-join the CGEP community to advance serious strategic and policy discussions on some of the most significant challenges we face today relating to climate and energy transition,” said Tommy Beaudreau. “This includes thinking through the energy mix, the revitalization of communities dependent on natural resource development, responsible sourcing of materials necessary for renewable energy and technology development, as well as environmental justice and the rights of Indigenous communities.”

Ambassador Sarah Bianchi, Senior Managing Director and Chief Strategist of International Political Affairs and Public Policy at Evercore, previously served as Deputy United States Trade Representative. In this role, Amb. Bianchi worked on supply chain issues and policies related to the clean energy transition. She also oversaw trade issues related to Asia, Africa, investment, services, textiles, and industrial competitiveness.

“I am thrilled to be joining this class of Distinguished Visiting Fellows, and to continue working at the intersection of climate change and trade policy as part of the Columbia community,” said Amb. Sarah Bianchi. “I am eager to work with CGEP’s experts to build and advise on new initiatives focused on this space, including the geoeconomics of the energy transition, global industrial policy, and expanding dialogues on key global trade issues as they relate to energy and climate change.”    

Sir Stephen Lovegrove, who recently joined SIPA’s Institute of Global Politics as a Carnegie Distinguished Fellow, served as the UK’s National Security Advisor from March 2021 until September 2022. In this role, Sir Stephen was responsible for the UK’s response to Russia’s invasion of Ukraine and the withdrawal from Afghanistan. He also oversaw the signing of AUKUS, the trilateral security pact among Australia, the United Kingdom, and the United States. Prior to his role as national security advisor, Sir Stephen was the permanent secretary for the Ministry of Defense from 2016 to 2021, a role he also performed at the Department for Energy and Climate Change from 2013 to 2016.

“As a Distinguished Visiting Fellow, I am excited to engage with students and colleagues on the security implications of the energy transition and the future of nuclear power,” said Sir Stephen Lovegrove. “I look forward to working with the Center on Global Energy Policy and the School of International and Public Affairs on these critical issues.”

Mari Pangestu was the World Bank Managing Director of Development Policy and Partnership from 2020 to 2023. Prior to joining the World Bank, Mari Pangestu served as Indonesia’s Minister of Trade from 2004 to 2011 and as Minister of Tourism and Creative Economy from 2011 to 2014. Ms. Pangestu was also a Senior Fellow at Columbia University’s School of International and Public Affairs.

“As a Distinguished Visiting Fellow, I am eager to contribute to the critical discourse on the energy sector’s pivotal role in global climate mitigation strategies,” said Mari Pangestu. “My focus spans understanding and addressing energy access challenges in least developed countries, along with the complexities of navigating the energy transition in middle-income countries. The Center on Global Energy Policy provides the global and cross-country perspectives needed to address complex issues such as energy access and transition.”
