As director of national security research for the Pew Environment Group’s Clean Energy Program, David Catarious brings expertise on the intersection between the environment and national security, as well as on the need for national policy to ensure an energy-secure future.

Prior to his work with Pew, Catarious was a research analyst and project director at CNA, a nonprofit think tank, where he directed a team of more than a dozen senior retired admirals and generals who examined the relationship between national security, energy security and climate change. As part of that effort, the group published three reports, including a pivotal study, National Security and the Threat of Climate Change, in 2007.

Catarious has also served as a Congressional Science Fellow for the American Association for the Advancement of Science with Rep. Edward Markey of Massachusetts. On the Hill, he focused specifically on issues of climate change, energy independence, biofuels, renewable energy and the Arctic National Wildlife Refuge.

Since 2007, Catarious has served as a fellow and member of the board of principals at the Truman National Security Project. Catarious holds a bachelor’s and master’s degree in mathematics from Virginia Tech and a Ph.D. in biomedical engineering from Duke University.
