Dr. Edward (Ned) Vizy is a Research Scientist Associate in the Department of Geological Sciences at the University of Texas at Austin. He is an atmospheric scientist, and his work is focused primarily on understanding regional climate variability/climate change over the tropics/sub-tropics including Africa and the Americas. Dr. Vizy has over fifteen years experience developing and adapting high resolution regional climate system models for use in addressing climate related issues.

Dr. Vizy's current interests include understanding the relationship between the development of precipitation systems and the diurnal cycle of rainfall and how they relate to extreme weather, understanding the role of eastern South Atlantic ocean/atmosphere feedback processes and their influence on regional climate variability, and how extreme weather events (i.e., droughts, heat waves, floods, hurricanes) are projected to change in the future and assessing what impact these changes will have on society. Dr. Vizy earned his PhD in Atmospheric Science from Cornell University in 2003.
