His teams are noted for maintaining 24/7 situational awareness of world events to isolate those activities pertinent to the Homeland Security and Homeland Defense mission areas, and mine data for relevant information. They develop that information into actionable knowledge by performing probability assessments, developing potential courses of action, executing the mission, monitoring the situation and adjusting as necessary.
