Abigail Regitsky

Senior Associate, U.S. Policy and Advocacy

Abigail works on Breakthrough Energy’s U.S. Policy and Advocacy team, where she helps implement Breakthrough Energy’s climate policy priorities, focusing on industrial decarbonization, embodied carbon in buildings and other materials, and clean electricity standards.

Prior to joining Breakthrough Energy, Abigail worked on Capitol Hill, most recently as professional staff for the majority on the House Select Committee on the Climate Crisis. Her work focused on climate change mitigation, primarily developing policy recommendations for the industrial and manufacturing sector, buildings, and clean energy innovation. Previously, Abigail was a AAAS Congressional Science Fellow for Senator Tina Smith, where she helped develop and introduce the Senator's Clean Energy Standard Act of 2019, among other energy and environment work.

Before working on the Hill, Abigail earned a PhD in materials science and engineering from MIT, where her research tried to better understand biomineralization for future applications in sustainable materials processing. Originally from Indonesia, she grew up in the Atlanta suburbs and received a BS from Georgia Tech. Abigail lives in DC with her husband, Ross, and their dog, Luna, and enjoys playing board games, baking, and photography.
