Professor Criminale completed his baccalaureate degree at the University of Alabama in 1955. He received his doctorate at the Johns Hopkins University in 1960. His research focuses on the areas of initial-value problems in shear flows, large-scale oscillations in turbulent flows, mixing, and nonlinear mechanics. Professor Criminale is supported in his research by several agencies. Professor Criminale is the recipient of many honors which include: the Alexander von Humboldt Senior Research Award; Fellow, American Physical Society; Guest Scientist, Stanford-Ames Turbulence Research Center; the Faculty Research Award, Battelle Pacific Northwest Laboratories; and a Royal Society Fellow in the United Kingdom. He has also been a guest professor in Brazil, Canada, England, France, Germany, Italy, Scotland and Sweden.

Research Interests

Problems dealing with the breakdown of laminar flows and transition to turbulence. Particle dynamics, mixing, and flow control are topics being investigated using methods developed in the fields of stability and turbulence. Prototypical flows range from channel flows and boundary layers to those encountered in a stratified geophysical environment. Nonlinear mechanics.
