Ph.D., Astrophysical, Planetary, and Atmospheric Sciences University of Colorado, 1997
  • major thesis topic: application of low-order synchronized chaos to the prediction of relationships between                         large-scale weather patterns in the Northern and Southern hemispheres, using a Green’s function method to represent the time-lagged coupling between the corresponding quasigeostrophic midlatitude channel models, truncated to a small number of modes 
  • minor thesis topic: development of global entropy metric for cloud systems to enable the formulation of a second-law constraint on cloud morphogenesis based on water-cycle throughput
