Brief Research Interests: 

Geophysical imaging to study the structure and composition of Earth’s interior


Note to students seeking a Masters or Ph.D. advisor

If studentships are available, you will find them available here. However, since I am approaching retirement, I am not currently accepting new Ph.D. students. Please do not contact me by email if you are interested in being my student - I will not respond. Please check back here periodically to see if any studentships become available.



Use of geophysical imaging methods (primarily magnetotelluric and electromagnetic, also including seismic, potential fields) to study the structure, fluid distribution, composition, temperature and state of the Earth's interior from the near-surface scale to the deep mantle. High performance computation including massively parallel architectures including GPU and hybrid computing. Instrumentation and sensor research and development. Renewable energy including geothermal power. Studies of fluid flow in cracked, porous, reactive media including seafloor hydrothermal systems.
