Graduate Student Opportunities

Funding opportunities are available for both M.Sc. and Ph.D. student applicants with interests in mantle convection studies and the modelling of fundamental heat transport processes in viscous fluids. Applicants should possess good communication skills and a first degree in mathematics, physics, geophysics or an appropriate branch of engineering. Potential students would be enrolled in either the Department of Physics, the Department of Astronomy and Astrophysics or the Department of Geology . The start date is typically August of each year. However, as the University of Toronto has only one intake time per year, it is essential that interested students begin the application procedure prior to the end of the previous year (November). Interested Masters and PhD program applicants are encouraged to contact me directly at lowman@utsc.utoronto.ca regarding potential research projects for 2008. Projects on offer include but are not limited to:

• Studies of the effect of spherical shell thickness on the wavelengths of mantle convection

• The effect of mechanical boundary conditions on the secular cooling of planetary interiors

• Power-law relationships for Rayleigh number and Nusselt number in the hard-turbulent regime for 3D convection

• The feedback between plate motion and mantle convection

• Numerical methods in computational fluid dynamics

• The heating modes and cooling processes in terrestrial planets

• Investigation of the feedback between mantle convection and surface motion

• The supercontinent cycle and its effect on the long wavelength heterogeneity of mantle convection

• Computer visualisation applications for 3D computational fluid dynamics
