Science Advice and Guidance for Emergencies (SAGE)

Science Advice and Guidance for Emergencies (SAGE) is a scientific information resource and response program within the Science & Technology Directorate (S&T) designed to aid the Department of Homeland Security (DHS) in mitigating, responding to, and recovering from national and regional incidents such as hurricanes, chemical spills, terrorist activity, or pandemic diseases. Comprised of members from the Security, Preparedness, and Continuity Office, SAGE accomplishes these tasks by providing scientific and technical data, context, and recommendations when called upon by stakeholders. The information provided comes from a robust network of subject matter experts (SMEs) from government, academia, and industry. Our experts have volunteered to provide this advice freely. 

Why SAGE?

SAGE provides the following methodology for quickly and effectively conveying science and technology recommendations during a crisis:

  • Establishes a domestic focal point for the capacity to provide intersecting field advice.
  • Develops a transnational framework for communicating and exchanging ideas and advice.
  • Promotes mutual understanding and strengthens trust from providers to users.
  • Prepares stakeholders to adequately provide effective and timely advice.
  • Forms a scientific means for strategic communication to the public interest.

"In a connected and multifaceted world, the ability of government to respond to complex emergencies requires expertise that may exceed that of the federal workforce. SAGE provides a mechanism to tap into all sectors of the United States by recruiting a group of experts before a crisis occurs.  These experts help inform decision makers on timely critical matters requiring solutions that cross disciplinary boundaries. I am proud to be part of the SAGE enterprise to better prepare the Department and Nation as we prepare the future."  —Dr Sam Howerton, S&T Chief Scientist
