Research Interests

• Large scale atmospheric dynamics (balanced dynamics, potential vorticity inversion, wave-vortex interactions, dynamics of middle-latitude storm tracks, etc.)
• Numerical methods for fluid flows (the application of contour-advective methods to models of the Atmosphere and Ocean, Optimal algorithms for wave-vortex interaction problems, numerical weather prediction)
