Jeannette Sutton, PhD, is an internationally recognized scholar of alerts and warnings, identified by Stanford University as being among the top 2% of scientists worldwide in 2024 and 2025.
With funding from the National Science Foundation, the National Oceanic and Atmospheric Administration, the US Geological Survey, and the Federal Emergency Management Agency, she has studied, taught, and written about risk communication, alerts, and warnings for more than two decades.
Her signature project, sponsored by the Integrated Public Alerts and Warnings System (IPAWS) program at FEMA, led to the design, development, and deployment of the Message Design Dashboard (MDD), a software used by emergency managers and other public safety communicators to craft effective messages.
The data backbone and analog to the MDD, The Warning Lexicon, is used internationally for message development across a full range of hazards. A twin document, the Post Alert Lexicon, provides the structure and contents for “all clear” messages issued post-event. Additional studies on AMBER alert messaging have resulted in recommendations for effective missing persons messages.
She works at the University at Albany as an Associate Professor in the College of Emergency Preparedness, Homeland Security and Cybersecurity; serves as an Advisor to EM1; is co-host on The Alerting Authority; and is the founder and owner of The Warn Room.
