Hurricanes/aftermath

Lenore P. Tedesco

Assistant professor, geology
(317) 274-7484 (Purdue-Indianapolis)
E-mail: ltedesco@indyvax.iupui.edu

Has taught courses on geology, oceanography, dinosaurs, and sedimentology and stratigraphy. Since 1984 has studied wetland stability and coastal processes in South Florida, Everglades and Bahamas. In Everglades National Park, has studied the role of sea level rise and catastrophic storms in controlling the stability of coastal wetlands. Has had research grants to study post-hurricane sediment redistribution, specifically how the coastal and shallow marine environments of South Florida changed after Hurricane Andrew.

Tornadoes

Ernest M. Agee

Professor, atmospheric science
(765) 494-4753

Has studied Doppler radar images of tornado events, especially those that occurred without operational warnings. Is developing a new conceptual model for detecting early tornado warning signatures in color Doppler weather radar images. Is a fellow of the American Meteorological Society. Served as U.S. representative to the International Association of Meteorology and Atmospheric Physics. Was a member of the United States National Committee of the International Union of Geodesy (science of the size and shape of the earth) and Geophysics, a position to which he was appointed by the National Academy of Sciences.
