The Science, Technology, Innovation Exchange (STIx) is meant to communicate the big ideas, positive social impacts, and disruptive capabilities that have resulted from DoD S&T investments. This series of short videos features talks in fields of science, technology, and STEM, are presented by DoD and DoD sponsored participants, from across the Department and that span careers from graduate students to senior researchers.
These in-depth stories were developed to raise awareness about the importance of Defense laboratories, engineering centers, and warfare centers as unique catalysts for innovation as well as showcase the critical work they perform. By sharing stories about the people and institutions behind science and technology, DoD STEM aims to increase interest in STEM careers.
Dr. Nader Vadiee, "Closing the Circle: Innovative STEM Programs Empower Native American Students"
The Native American population is not underrepresented, but unrepresented in the STEM fields. Although they make up 1.2 % of the total population, Native American/Alaska Natives represented only 0.4% of all engineering bachelor degree recipients, 0.3% of the engineering workforce, and 0.1% of all engineering faculty SIPI, home to one of the largest tribal college engineering programs in the United States, received funding from the NASA Tribal College and University Experiential Learning Opportunity (TCU-ELO) grant to allow students to work with rovers in a simulated Martian environment called a Mars yard and to expose Native American students to more science and math courses.
Dr. Paul Jaffe, "Space solar energy as the answer of our future energy needs"
We know our nation and the world are in need of sustainable sources of energy. One possibility is space solar, in which sunlight is collected in space (where it is brighter than anywhere on earth and is unaffected by clouds or night) and sent wirelessly to the earth. This would be a clean, constant, globally dispatchable source of energy.
Dr. Rajesh Naik, "Exploiting Biology to Build Better (Energetic) Materials"
Biological systems have evolved a vast array of diverse molecules and functional structures. They offer inspiration and exciting opportunities for creating biomimetic materials, structures and devices. The assembly of individual biomolecular units into well-defined, higher-order functional structures is a hallmark of biological systems, and is exemplified in the self-organization of biological building blocks into supramolecular structures (e.g. proteins, viruses).
Dr. Robert Ghrist, "Mathematics & the Visual Imagination"
Of all the STEM subjects, the M – Mathematics – is the most visual, dynamic, and imaginative. Why, then, is it the source of so much boredom, confusion, and dread? The task of communicating the beauty of Mathematics is a uniquely visual challenge, and the frequent failure to inspire is perhaps related to the difficulties of design, illustration, and animation.
Dr. Sharad Sharma, "Virtual Reality Environments for Emergency Response, Training, & Decision Making"
The big question that my research seeks to model is a collaborative virtual environment (CVE) that includes human behavioral modelling for emergency response, training, and decision making strategies. Modeling such an environment is very important because in the real-time emergencies we experience in day-to-day life, there is a need for preparation to extreme events.
