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.
Could different molecular pathways in men and women contribute to sex differences in PTSD?
Post-traumatic stress disorder (PTSD) affects 8 million people each year, with women being more than twice as likely to be affected. What could be contributing to this alarming gap in prevalence? A common feature of PTSD is the failure to recall the specific details of the traumatic event and thus, fear can generalize from traumatic to safe contexts.
Dr. Aude Oliva, "The Time Machine in Your Head"
The human brain is a time machine: we are constantly remembering our past and projecting ourselves in time and space in the future. Neuroscientists are explorers who study how the time machine works, how to repair it when it is damaged, and how to improve it.
Dr. Charles Kamhoua, "Cyber Physical Security Game"
Cyber Physical Systems (CPS) and Internet of Things (IoT) devices such as sensors, wearable devices, robots, drones, and autonomous vehicles, facilitate the Intelligence, Surveillance, and Reconnaissance to Command and Control and battlefield services. The capability of such systems to autonomously secure themselves is a key foundation for operational resilience but the extensive use of information and communication technologies in such systems makes them vulnerable to cyber-attacks.
Dr. John Rogers, "Transient Electronics"
A remarkable feature of modern integrated circuit technology is its ability to operate, almost indefinitely, in a stable, reliable fashion, without physical or chemical change. Recently developed classes of electronic materials create an opportunity to engineer the opposite outcome, in the form of devices that dissolve, in a controlled fashion, completely and harmlessly in groundwater or biofluids.
Dr. Raychelle Burks, "Catching Students at STEM Intersections"
Research in applied science often captures and holds student attention because they’re working on relatable “real world” problems. Students, however, might need advanced skills to work on applied projects. To address this Catch-22, students in my lab work on intersecting projects.
