Richard F. Katz

Professor of Geodynamics

The research interests of my research group FoaLab are centred around the dynamics of fluid–solid systems with chemical, mechanical and thermodynamic interactions between phases. In particular: applications to geophysical systems; pattern formation in two-phase systems; fluid focusing and localization; shear and reactive instability in partially molten materials; plate boundary volcanism; reactive flow of magma and hydrous fluids through the mantle; geochemical predictions and comparison with geochemical observations; ice-sheets and sub-glacial hydrology; the integration of large-scale computation, analytical theory, and laboratory fluid dynamics experiments.

My teaching includes: Intro to Physical Thermodynamics (1st year), Problem solving in Earth Sciences with Matlab (2nd year), Geodynamics & Continental Deformation (3rd year), and Seminar in Mantle Dynamics, Seismology and Rheology (4th year).
