DSO Overview 1. Good morning and welcome to the first of the technical sessions here at DARPATech 99. I will provide you with a brief overview of the breadth of the Defense Sciences Office and then you will hear in depth from several program managers. You will hear both about some of the exciting efforts going on within our Office as well as several of the new directions that we are pursuing. 2. The philosopher Confucius once said: “If a man does not give thought to problems which are still distant, he will be worried by them when they come nearer.” I view our role as “technology nurturing and technology harvesting” -- looking out into the future and identifying immature technologies which we believe will have a significant impact on the Department of Defense and turning them into a reality sooner rather than later. Our charter is purposefully broad and we put no bounds on the technical fields that we might pursue. 3. In order to accomplish this mission, program managers must be true “techno-scouts,” always on the prowl for the next miracle that might make a difference to our national defense. In some cases we catalyze the creation of new technologies so that others may bring them to fruition. In other cases, we work very closely with the military and intelligence communities and have brought technologies to the point of acquisition. The Defense Sciences Office is the most technically diverse office here at DARPA. The backgrounds of our program managers range from chemistry, physics, and materials science to engineering, mathematics, and biology and medicine. Since many of the most innovative approaches to problem solving do not fit neatly into a single field, our Office focuses on both multidisciplinary and interdisciplinary efforts. In order to bring together the expertise of such a diverse group of experts, we rely heavily on teaming between universities, Service and federal laboratories, small businesses and large industries. 4. As outlined in Dr. Fernandez’s overview, the work of the program managers in the Defense Sciences Office falls into four main thrust areas: Biological Warfare Defense, Biology, Defense Applications of Advanced Mathematics, and Materials and Devices for New Military Capabilities. 5. As you heard from Dr. Alexander, Biological Warfare Defense is a critical focus area of DARPA and the Department of Defense. Most of the work in this area takes place in the Defense Sciences Office. Our efforts are focussed on broad spectrum therapeutics to target common mechanisms of pathogenesis and to modulate the human biological response to pathogens; advanced medical diagnostics -- allowing soldiers and sailors to determine the presence of pathogens in real time and in the absence of recognizable signs and symptoms (when pathogen numbers are still low and the prognosis for recovery is still good); novel methods of external protection including enhanced fabrics, methods for air filtration and water purification, and improved methods of environmentally sound decontamination; the ENCOMPASS system, a unique tool to manage the consequences of a biological or chemical warfare attack; and an emerging effort in genomic sequencing which will have an impact on the fundamental science underlying a number of our current projects. I should note that we are working very closely with our colleagues in the military Services, the intelligence community, and the civilian health agencies to ensure coordination and that there is no duplication of effort. 6. Biology at DARPA is more than just Biological Warfare Defense. Our work draws heavily from both biology and engineering. In our program on tissue-based biosensors, we are learning how to grow and stabilize living cells and tissues on abiotic substrates to provide a physiological basis for the detection of pathogens and toxins. An understanding of the interface between the biotic and abiotic worlds is critical to our ability to exploit the unique locomotion and chemical, visual, and aural sensing capabilities of animals. Thus, we are also exploring methods to train and control insects and other small animals to find hazardous materials, including biological and chemical agents and explosives. Finally, we are learning from nature and trying to imitate it in projects in bioinspired systems and biomaterials and processing. 7. Mathematics plays a critical role in a number of areas within the Defense Sciences Office. Our efforts in signal and image processing, electromagnetic calculations, fast and scalable computational algorithms, and advanced mathematics for micro- structural process control share a common feature: the development of mathematical paradigms that enable maximum performance at minimum cost. In order to accomplish this, we leverage new mathematical representations that go far beyond what is possible through either the evolution of current methods or the development of advanced computer hardware. The experiments and theory that we deal with are focussed on taking data with a very high degree of dimensionality and simplifying it into problems that are more rapidly and easily solved. Key to the success of this program is its strong linkage between mathematical formalism and real-world testing. 8. Materials and materials processing have been the traditional strengths of the Defense Sciences Office and they continue to play a critical role in our future. The efforts in this thrust are broken down into several key technology areas: functional materials, which includes materials which rely on the spin degree of freedom for their unique properties (e.g., gigantic magnetoresistive materials and materials for advanced magnets), thermoelectric materials, materials for holographic data storage, and molecular electronics; smart materials which sense and respond to the environment around them (such as piezoelectric materials and electroactive polymers); structural materials such as ultralightweight metallic structures, body armor; and solid freeform fabrication strategies; mesoscopic-sized machines for soldier cooling, pumping, sampling, and air and water purification; and novel methods of power generation and energy storage (including small fuel cells and fuel processors and microturbines); unique ways to scavenge (or “harvest”) energy from the environment (e.g., solar photovoltaics, ocean sediments, and bio-fuel cells). Key to the success of these efforts is not just the development and testing of new materials, but the demonstration of these materials in components and devices of interest to the Department of Defense. 9. None of these efforts work in isolation. As I have indicated in this brief introduction and as you will hear in the next few presentations, there is a tremendous synergy between the thrust areas in the Defense Sciences Office. Just as we develop a team of extramural researchers where the effort and output of the whole is much greater than that of the isolated parts, the same is true of DSO. Our internal efforts are closely coordinated so that we bring a team approach to the solution of critical problems facing the Department of Defense and our nation. 10. Opportunities in the Defense Sciences Office will be expanding during the next fiscal year. These include exploiting recent advances in genomic sequencing and therapeutic development to help solve problems in biological warfare defense; the development of biomolecular and biomimetic systems to enhance our ability to both use and learn from Mother Nature; the virtual electromagnetic test range to eliminate the need for repetitive designing, building, and testing of new stealth materials and antennas; new and expanded uses for mesoscopic machines and ultrahigh energy density power systems; and novel materials and materials processing concepts including combinatorial and computational guided synthesis and simulation, multifunctional materials, spins in semiconductors, nanoparticles, compact hybrid actuators and new methods for the assembly of micro- and nano- devices. Finally, the Defense Sciences Office is always interested in new and cool stuff -- if you have an idea that will revolutionize the world (and does not violate the laws of physics), we want to hear about it!
