Episode 36: The Hypersonic Materialist

In this episode of the Voices from DARPA podcast, William (Bill) Carter, a program manager since 2018 in the agency’s Defense Sciences Office, recounts his scientific journey. It began with childhood wonder amidst star-blazoned New Mexico skies and high-school summer jobs at Los Alamos National Laboratory, and has taken him now, literally, to leading edges of materials science and engineering. His portfolio of programs at DARPA aims to deliver materials that increase the practical range of hypersonic vehicles by breaking the “heat barrier,” that is, by taming the extreme heat flows on surfaces of hypersonic platforms; thermoelectric materials and systems for quiet, portable power generation in contested areas; and nanoscale-engineered materials suitable for such jobs as replacing tendons and printing electronics as easily as laser-printing a photograph. Says Carter, “I have absolutely unbounded optimism about the potential for science to solve today’s most important problems and I think materials science can contribute.”
