PhD Position: Dynamic Nuclear Polarization using Electron-Nuclear Double Resonance
... Nuclear magnetic resonance is an amazingly powerful technique for studying everything from drug molecules to working human brains. However, many NMR experiments are limited by the small fraction of nuclei which are spin polarized. Electrons are more easily polarized but electron paramagnetic resonan ...

Magnetotellurics
Magnetotellurics (MT) is an electromagnetic geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface. Investigation depth ranges from 300m below ground by recording higher frequencies down to 10,000m or deeper with long-period soundings. Developed in the USSR and France during the 1950s, MT is now an international academic discipline and is used in exploration surveys around the world. Commercial uses include hydrocarbon (oil and gas) exploration, geothermal exploration, mining exploration, as well as hydrocarbon and groundwater monitoring. Research applications include experimentation to further develop the MT technique, long-period deep crustal exploration, and earthquake precursor prediction research.
