Types of Projects Supported

SEG supports DHS S&T projects within the Explosives Division and the Transportation Security Laboratory (TSL). Project topics have included man portable air defense systems (MANPADS) and ways to counter them, airport checkpoint security, detection of chemical and biological threats, sensors, and communications systems. SEG has supported all phases of DHS S&T programs from creation of source selection material and execution of the source selection process through technology development and demonstration and all the way to transitioning technology to partners in the field.

Analyses Performed

SEG utilizes its full range of capabilities in support of DHS S&T projects. SEG frequently serves as Cost Subject Matter Experts (SME) during source selection, Cost/SE/OR analysts during program execution, and key advisors during technology transition. The SEG blend of cost expertise and systems engineering/operations knowledge and background allows it to appropriately bring cost considerations into focus during the technology development process. Bridging that gap between the detailed engineering perspective and the operational and cost perspective is an SEG specialty.
