Emergency Management

Emergency Management

The Emergency Management (EM) subcommittee works to improve decision-making by organizations that share information relating to emergency response and emergency management and to increase the ability to prepare for, respond to, and recover from emergency situations.

Effective information sharing is critical to the success of a coordinated emergency response. The EM subcommittee supports emergency-related services (including preparing first responders and responding to disasters), information sharing, and activities such as homeland security and resource communications management. The EM subcommittee leverages existing and emerging technology, lessons learned, and prior successes to:

  • Enhance data exchange standards, internal processes, and operational effectiveness.
  • Promote interoperability between national and international organizations, including federal, state, local, and tribal organizations, utilizing emergency-related data and information.


As subcommittee steward, the Department of Homeland Security’s (DHS) Science and Technology (S&T) First Responders Group (FRG) manages the EM subcommittee. The EM Subcommittee Chair is Dan Cotter, Director of DHS S&T FRG. ​ The EM subcommittee has an inclusive governance structure that includes federal, state, local, industry, and, where necessary, international partnerships. The EM subcommittee also includes key stakeholders, practitioners, advisors, and subject matter experts from private sector organizations as well. Working with groups such as the Emergency Interoperability Consortium (EIC), the subcommittee stewards ensure that as the subcommittee continues to evolve, it meets the needs of the broader EM community.
