Keynote Speaker for the conference is Tim Marshall. Tim attended Northern Illinois University at DeKalb, attaining a B.S. degree majoring in meteorology in 1978. As an undergraduate student there, he and classmates surveyed some tornado damage paths of the 1974 Super Outbreak during informal travels to the National Climatic Data Center to collect severe weather data. Marshall went to Texas for graduate school, seeing his first tornado a few hours after entering the state. In 1978, he began storm chasing in west Texas and Oklahoma. During the past 30 years, Tim has filmed more than 200 tornadoes and experienced 17 hurricanes. In 2004, he rode out Hurricane Ivan in Pensacola, Florida and, in 2005, Tim rode out Hurricane Katrina in Slidell, Louisiana. In 2008, Tim saw Hurricane Ike on Galveston Island. Tim has appeared on dozens of television programs including those on The Discovery Channel, The Learning Channel, National Geographic, and The History Channel. He has been on The Oprah Winfrey Show twice.
