In our complex world, data analytics is increasingly important for national security. It involves the integration of disparate, dynamic, and distributed data to improve our ability to identify, characterize, and forecast critical events. A-1 performs basic and applied research focused on modeling and understanding emerging threats such as disinformation, disease outbreaks, political instability, and nuclear proliferation. 

  • Development of workflows and tools to ingest, process, and analyze large heterogenous real-time data streams to forecast events
  • Incorporating human behavior into models
  • Expertise applying statistical, mechanistic, machine learning, and agent-based modeling techniques to real-world national security challenges
  • Using natural language processing techniques to elicit useful signals from many different text modalities across different languages
  • Disease modeling and forecasting (e.g., COVID forecasting)
  • Political instability modeling
  • Dis/misinformation analysis
  • Data fusion at scale to inform emerging global threats

Chemical, Biological, and Radiological Agent Dispersion Modeling

Chemical, Biological, and Radiological Agent Dispersion Modeling


Whether released by a terrorist or the result of an industrial accident, understanding the dispersion of a harmful agent is vital for effectively responding to aerosolized or gaseous threats. A-1 provides research, physics-based modeling tools, information, and emergency response to national organizations as they work to protect and respond to chemical, biological, radiological, and other threats.

  • Chemical, biological, radiological, and nuclear plume modeling
  • Atmospheric sciences
  • Fast-running dispersion modeling
  • Urban and indoor plume modeling
  • Complex terrain modeling
  • Fire spread modeling

National Security Information Systems

National Security Information Systems

A-1 develops information systems that support a variety of U.S. government entities in the areas of policy advice, non-proliferation, treaty verification, and threat assessment.

  • Information systems to support analysis of export commodities for proliferation risk
