Resilient Systems Division

The DHS S&T Resilient Systems Division’s (RSD) mission is to rapidly develop and deliver innovative solutions that enhance the resilience of individuals, communities and systems. RSD explores solutions that enable the whole community to prevent and protect against threats, mitigate hazards, effectively respond to disasters and expedite recovery.


RSD’s vision is to strengthen our nation’s resilience to all-hazards disasters through science and technology-based solutions.


Jalal Mapar is the director of RSD.

RSD Focus Areas

Community Resilience

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

Critical Infrastructure

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

Cyber Physical Systems

Our nation has become more reliant on cyber-physical systems where computer networks control physical systems, such as Global Positioning System (GPS)-based technologies. RSD is developing technologies to identify the extent GPS is used in critical infrastructure sectors as well as assessing weaknesses within the data transfer and 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 risk-based analysis and planning applications that will help anticipate disasters and manage responses, researching ways to speed up disaster response and providing situational awareness to support decision making.

Evaluation Research

Evaluation research is used to assess people, processes, tactics, techniques, procedures and policies needed for implementing systems. RSD applies evaluation research data for the Transportation Security Administration in order to identify, select and train 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 continues to research hostile intent detection and how best to collect and evaluate high-quality biometrics to prevent illegal entry into the United States and speed legitimate travel. RSD is sensitive to the protection of individual privacy and S&T is committed to safeguarding the privacy and civil rights of our citizens.

RSD Customers

RSD’s primary federal customers are the following DHS components: Federal Emergency Management Agency, Transportation Security Administration, U.S. Citizenship and Immigration Services, U.S. Coast Guard, U.S. Customs and Border Protection, U.S. Immigration and Customs Enforcement, U.S. Secret Service, National Protection and Programs Directorate Office of Infrastructure Protection, Office of Health Affairs and Office of Intelligence and Analysis.
