Episode 37: Sounds of Innovation 1 Dec 21, 2020

Show notes

Welcome to Sounds of Innovation, a new intermittent feature of our Voices from DARPA podcast. Rather than hearing the voices of program managers, which is normally what you get in a Voices from DARPA podcast, in each Sounds of Innovation episode, you will hear some of the soundscapes of research and development…and learn just a little bit about what new world-changing capabilities those sounds could lead to.

Episode 36: The Hypersonic Materialist Dec 01, 2020

Show notes

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.”

Episode 35: Maxwell's Disciple Nov 05, 2020

Show notes

In this episode of the Voices from DARPA podcast, Tom Rondeau, a program manager since 2016 — first in the agency’s Microsystems Technology Office before switching over this year to the Strategic Technology Office — takes listeners on a kaleidoscopic tour of his efforts to usher wireless technology into a new era. Anchored in an emerging technology arena known as software-defined radio (SDR), his programs dive deeply into the pathbreaking hardware, software, computational techniques, power efficiencies, and innovation communities that it will take to do more with the electromagnetic spectrum than ever before. Think of every cellphone call ever made, of satellite communication, and now of billions of devices communicating wirelessly via apps and the internet. And now think beyond all of that. The tattoos of Maxwell’s Equations — which famously capture the behavior of electromagnetic waves as discerned by the 19th century physicist James Clerk Maxwell — on Tom’s forearms reveal just how devoted he is to his technology-development mission. “I look down at those every day and have a moment of awe about what we have been able to do,” he tells listeners. And then he has another moment of awe as he imagines how much more he might be able to pull off as a DARPA program manager.

Episode 34: The Orbital Optician Oct 16, 2020

Show notes

In this episode of the Voices from DARPA podcast, Stacie Williams, a program manager since 2019 in the agency’s Tactical Technology Office, reveals how a lifelong love of optical and photonic phenomena, beginning with fireflies during her childhood, is now unfolding in her stewardship of ambitious light-and-optics-centric programs at DARPA. One of these, the Deformable Mirror (DeMi) program, recently reached a milestone with the placement from the International Space Station of a dime-sized deformable mirror on a loaf-sized CubeSat platform. The goal of DeMi is to deliver cheaper, lighter, smaller telescope mirrors—in the form of a microelectromechanical system (MEMS)—that could open unprecedented options for space-based ISR (intelligence, surveillance, reconnaissance) technology that, in Stacie’s words, “helps us understand what’s going on with a space eyeview.” In another optics-tech effort under Stacie’s wing, researchers are learning how to design so-called metamaterials—with engineered microstructures that manipulate electromagnetic wavelengths—that also could greatly simplify, lighten, and cheapen far more massive, complex, and expensive conventional telescopes. In the podcast, Stacie also recounts her work beyond technology as a champion of science, technology, engineering, and math (STEM) education for economically disadvantaged communities.

Episode 33: The Verification Virtuoso Sep 23, 2020

Show notes

In this episode of the Voices from DARPA podcast, Matt Turek, a program manager since 2018 in the agency’s Information Innovation Office, discusses his portfolio of artificial intelligence (AI) programs that could not be more timely. Two of these programs map onto this harrowing moment in history where one of the most precious assets we can have as a society — trust in media and in various channels and modes of communications — is evaporating. Another program gets at a different kind of crucial trust: human trust in the AI tools that are becoming embedded and influential in our everyday lives and in government responsibilities including national security and defense. And in yet another program, Turek is asking the research talent out there to build one of the most powerful components of human intelligence into artificial intelligence: common sense. Turek says he hopes to encourage AI researchers to, in his words, “work together in ways that aren’t currently happening or maybe they didn’t envision happening.”

Episode 32: The Opportunity Hunter Sep 02, 2020

Show notes

In this episode of the Voices from DARPA podcast, Air Force Lt. Col. C. David Lewis, a program manager since 2018 in the agency’s Defense Sciences Office, takes listeners on a tour of the amazingly diverse portfolio of programs he oversees. The foci of these range from the deep math underlying optimization challenges, such as planning complex routes and managing supply chains, to using untapped signals in the atmosphere as indicators of both natural and human activities on the planet’s surface. He also shares a timely chronicle of his navigation, as a Black person, through the individual and systemic racism that confronted him as he pursued his love of science (which his sixth-grade teacher and key educational ally recognized) and later his ambition to become a fighter pilot (and even an astronaut), a physicist, and then to land what he calls his “dream job” as a DARPA program manager. Amidst the vexing challenges to fully open educational and professional opportunities to all Americans, David has a forwarding-looking message for listeners. “We are going to evolve,” he says. “It’s important for all Americans now to think about what they want the future to look like.”

Episode 31: Science 2.0 Aug 17, 2020

Show notes

In this thematic episode of the Voices from DARPA podcast, three program managers discuss the possibility that emerging technologies in the arena of artificial intelligence (AI) are converging toward an “artificial-science” toolset that could open an era we might designate as Science 2.0. The prospect of AI scientists making Nobel-prize-caliber discoveries is not around the corner, but it is a distinct possibility for the future, suggests program manager Jiangying Zhou of the agency’s Defense Sciences Office (DSO). On the way toward that ideal, adds program manager Joshua Elliott of the Information Innovation Office (I2O), we are likely to rely on scientifically-minded AI tools to pump up the efficiency of scientific discovery and to tap into the vast and growing reservoirs of data, which biological minds might not be as suited to make sense of as AI ones. For Bartlett Russell, also of DSO, perhaps the most important advance during the evolution toward a Science 2.0 era will reside in the use of AI tools that enable more people than ever to embrace the scientific enterprise. The more minds doing science, she says, the more discovery we can expect.

Episode 30: The Sensor Sorcerer Jul 07, 2020

Show notes

In this episode of the Voices from DARPA podcast, Dr. John Burke, a program manager since 2017 in the agency’s Microsystems Technology Office (MTO), goes deep, quantum-mechanics deep. The miniaturized, affordable, and ultrastable atomic clocks he hopes to make possible would kick in if the GPS system were to go down due to natural or adversarial actions. Such clocks could keep the military machine viable while also preserving or even enhancing the operation of civilian must-haves ranging from financial transactions to ridesharing (think Uber and Lyft). Burke has teams of researchers pursuing magnificently sensitive magnetometers for detecting objects, materials, and activities otherwise hidden underground, underwater, or behind bone. Among these sensors’ potential applications is real-time, in-field diagnostics and monitoring of concussions, whether in battlefield or sports field settings. These and other sensing capabilities Burke is fostering are based largely on the quantum-mechanical ways that atoms behave (e.g., the nuclear oscillations that serve at the invariant ticks of atomic clocks) or respond to signals in the world (e.g., faint magnetic fields from brains or buried ordnance). The overall goal of this quantum-mechanical finessing, Burke says, is to “peer around the curtain to see more and more of everything around us.”

Episode 29: The Light and Matter Maestro Jun 23, 2020

Show notes

In this episode of the Voices from DARPA podcast, Dr. Michael Fiddy, a program manager since 2016 in the agency’s Defense Sciences Office (DSO), takes listeners on a whirlwind tour of his programs. They all share a common thread, which stems from Fiddy's lifelong interest in how light — electromagnetic (EM) energy, more generally — interacts with matter. At DARPA, he has expressed that interest by challenging researchers to investigate whether cells interact with one another via EM signals; how it might be possible to use low-frequency EM radiation to see through just about anything (including metal); and how precisely engineered surfaces might tap into quantum mechanical phenomena (Casimir forces) in the vacuum of space in a quest for fuel-less propulsion technology. As Fiddy points out in the podcast, “We have been doing science for a few hundred years and there still is an awful lot that we don’t know.”

Episode 28: Swarm Commander Jun 11, 2020

Show notes

In this episode of the Voices from DARPA podcast, Dr. Timothy Chung, a program manager since 2016 in the agency's Tactical Technology Office, delves into his robotics and autonomous technology programs – the Subterranean (SubT) Challenge and OFFensive Swarm-Enabled Tactics (OFFSET). From robot soccer to live-fly experimentation programs involving dozens of unmanned aircraft systems (UASs), he explains how he aims to assist humans heading into unknown environments via advances in collaborative autonomy and robotics.

The SubT Challenge focuses on the underground – human-made tunnels, the urban underground, and natural cave networks. Teams from around the world vie for prizes via Systems (physical) and Virtual competitions, with air and ground platforms attempting to rapidly map, navigate, and search the subterranean domain.The OFFSET program envisions small-unit infantry forces seamlessly teaming with swarms of even hundreds of (UASs) and/or small unmanned ground systems. The program combines emerging technologies in swarm autonomy and human-swarm teaming.

Chung shares how he learned to see things not as impossible, but rather un-possible because, “it's not that it can't be done. It just hasn't been done yet.”
