Lichao Liu.

During his studies, Lichao Liu researched the surface nuclei magnetic resonance (NMR) which can be applied in the groundwater imaging and the management of environmental problems. The NMR signal originating from groundwater in the background of Earth’s magnetic field is extremely weak. Lichao Liu developed a new multichannel wireless surface NMR system and proposed the signal extraction method using spectral analysis method from low signal-to-noise ratio data.

The developed new surface system contributes to reliable and fast groundwater investigation and the signal extraction improves the accuracy of parameter estimate.

The PhD degree was completed at the Department of Geoscience, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
