It contains a fairly complete description of my research as a graduate student at the University of Texas. Feel free to download the file if you want all the details, but if you only want the highlights you might want to stick to the published articles listed above. Print copies are available from University Microfilm, Inc. Online version: dissertation*Quantum signatures of chaos in periodically driven systems*,

This dissertation, and the papers that are derived from it, were completed under the supervision of Dr. Linda E. Reichl while I was a graduate student at the University of Texas at Austin.
