RSD Focus Areas

Community Resilience

Community Resilience involves ensuring that all levels of society, from the community down to individual citizens, are better prepared for and can more effectively recover from incidents and/or disasters. RSD conducts social and behavioral science research to develop and aid communication strategies that will promote an improved, more effective resiliency within America’s communities.

Critical Infrastructure

Critical infrastructure includes the vast network of highways with bridges connecting tunnels, railways, utilities and buildings that are necessary to maintain normalcy in life. Transportation, commerce, clean water, and reliable power all rely on these vital systems but are vulnerable to natural disasters and are targets for terrorists. RSD is developing scientific approaches and applications to protect these resources from man-made or natural disasters.

Cyber-Physical Systems

Our nation has become more reliant on cyber-physical systems where computer networks control physical systems. We rely on Global Positioning Systems (GPS) to determine location and provide directions. RSD is developing technologies to identify the extent GPS is used in critical infrastructure sectors and assess weaknesses within the data transfer/cyber-physical systems.

Decision Support

Emergency managers need access to data from many sources and must quickly and accurately analyze that data to provide guidance on how to best respond to disasters. RSD is developing a risk-based analysis and planning applications that will anticipate and manage disasters, researching ways to speed up disaster response, and providing situational awareness to support decision making.

Evaluation Research

Evaluation research is used to assess personnel, processes, tactics, techniques, procedures and policies for implementing systems. RSD applies evaluation research data to the Transportation Security Administration (TSA) in order to identify, select, and train their screening personnel.

Security and Identification

RSD conducts research on how to improve security and identify unknown individuals. This is a broad area of research with many interrelated activities aimed at improving overall homeland security. RSD is sensitive to the protection of individual privacy and DHS S&T is committed to safeguarding the civil rights of our individual citizens.



RSD Customers

RSD’s primary federal customers are the Department's Intelligence & Analysis (I&A), National Protection and Programs Directorate Office of Infrastructure Protection (NPPD/OIP), Office of Health Affairs (OHA), Federal Emergency Management Agency (FEMA), Transportation Security Administration (TSA), U.S. Citizenship and Immigration Services (USCIS), U.S. Coast Guard (USCG), U.S. Customs and Border Patrol (CBP), U.S. Secret Service (USSS), and U.S. Immigration Customs Enforcement (ICE). RSD directly supports emergency responders; federal, state, and local emergency managers; and critical infrastructure owners and operators.
