Current Research

My research focuses on the development and transition of probabilistic watch and warning information for hazardous weather such as tornadoes, wind and hail.  Specfically, I study effective ways for end users to visualize, communicate and make decisions with that information. By integrating broadcast meteorologists into research and testing within NOAA's Hazardous Weather Tested, I am researching how probabilistic hazard information can be optmized for effective communication.  I collaborate with reseachers at both NOAA's Global Systems Division and the National Severe Storms Laboratory.  In addition, I have led software testing for a program known as Hazard Services, which is the platform National Weather Service forecasters will use to issue weather warnings.  Before coming to CIRES, I was a researcher for CIMMS at the University of Oklahoma.  Before that, I was an on-air broadcast meteorologist.  I worked extensively in severe weather markets, including KLBK in Lubbock, TX and KETV in Omaha, NE.
