The Sensors, Signatures, and Aerosol Technology (SSAT) branch of the ECBC R&T Directorate specializes in the study and detection of chemical, biological, radiological, and nuclear hazards in air to prevent exposures to both military personnel and the general public. These threats come in many forms but are often airborne in nature, and require highly specialized facilities and equipment to conduct the related aerosol studies needed for evaluation and detection of these threats. The research involved covers many areas, including methods for particle generation, measurement, sampling, and analysis.
Currently, research opportunities are available in the following areas: (1) improved methods for the generation of low and high concentrations of solid and liquid aerosols, (2) development of particle sampling methods to improve efficiency and biological sample viability/integrity, (3) evaluation of the relationship between the inactivation of organisms in air and on surfaces, (4) evaluation of micrometer and nanometer size particle deposition in human and animal respiratory system physical models recently developed from live animal CT scans with 3D printing techniques, and (5) improved methodology for re-aerosolization and quantification of inert and biological particles from various surfaces.
