The DHS Science and Technology Directorate (S&T) is the Department’s primary research and development arm and manages science and technology research, from development through transition, for the Department's operational components and first responders.

  • Misuse of a Mobile Driver’s License (mDL) Investigative Aid

    Mobile driver’s licenses are gaining traction in the United States, though implementation varies across the nation. A mobile driver’s license (mDL) is a digital representation of a state-issued driver’s license that is stored on a mobile device. Cases of identity fraud associated with digital identities will likely increase as mDL usage becomes more widespread. As a result, investigators will need to be prepared for this new technology and know what type of evidence may support investigations. 

  • Chemical Security Analysis Center – Ammonia Safety and Training Institute Cooperative Research and Development Fact Sheet

    CSAC entered a Cooperative Research and Development Agreement with the Ammonia Safety and Training Institute in July 2022.The goal of the collaboration was to use modeling to improve emergency response and conversely to allow emergency response needs to drive improved modeling and model development.

  • Fighting Fires and Saving Lives Through Science and Technology

    The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) works closely with first responders to improve their safety and effectiveness – lending expertise, conducting research and development, and funding innovation to ensure our nation’s public safety services are well-equipped to provide aid in times of crisis

  • Lane-Based Self-Service Screening Fact Sheet

    The S&T Screening at Speed Program, along with the TSA Innovation Task Force, is developing a lane-based self-service screening checkpoint for PreCheck® travelers to increase autonomy, reduce pat downs and bag inspections, and give Transportation Security Officers (TSOs) more time to assist other passengers. While lane-based self-service screening may at first look like a normal checkpoint, its video prompts and option to self-resolve alarms with minimal intervention from TSOs is a whole new experience.

  • Passenger Self-Service Screening Fact Sheet

    Through concept designs, prototypes, hardware, and video analytics development, the S&T Screening at Speed Program, along with the TSA Innovation Task Force, is reimaging the airport screening experience. Passenger self-service screening aims to provide more autonomy to travelers, reduce pat downs and bag inspections, and optimize TSA resources while meeting security screening standards.

  • Pod-Based Self-Service Screening Fact Sheet

    The S&T Screening at Speed Program, along with the TSA Innovation Task Force, is developing a pod-based self-service screening checkpoint for PreCheck® travelers to increase autonomy, reduce pat downs and bag inspections, and give Transportation Security Officers (TSOs) more time to assist other passengers. The futuristic pod-based checkpoint design offers an exclusive experience for travelers to go at their own pace, ideally reducing stress and increasing traveler satisfaction at the checkpoint.

  • Screening at Speed Program Fact Sheet

    The Department of Homeland Security (DHS) Science and Technology Directorate’s (S&T) Screening at Speed Program invests in technologies and techniques that will bring that vision closer to reality.

  • Wildfire Sensor Technology Fact Sheet

    Wildfires across the U.S. and around the world are becoming more frequent, costly, and dangerous. DHS S&T is working with the U.S. Fire Administrator, N5 Sensors Inc., TechNexus, and the Virginia Innovation Partnership Corporation to develop and test early wildfire detection technology to assist the Federal Emergency Management Agency and state and local emergency management partners.

  • Biological Threat Characterization Fact Sheet

    Biological Threat Characterization develops and maintains scientifically robust capabilities across the biodefense spectrum.  These capabilities inform national homeland defense activities to prevent, respond to, and recover from a biological attack on the homeland.

  • Chemical Threat Characterization Fact Sheet

    Chemical Threat Characterization develops and maintains scientifically robust capabilities across the chemical spectrum.  These capabilities inform national homeland defense activities to prevent, respond to, and mitigate the impact of a chemical attack on the homeland.
