Dr. Marina Karagianni is an experienced research associate of the NMR lab of the NCSR “Demokritos”. She received her B. Sc. in Physics, in 1990 from the Department of Physics, National and Kapodistrian University of Athens and her PhD in the Physical Science in 1998 from the School of Applied Mathematical and Physical Science of the National Technical University of Athens. The research work of her PhD thesis was implemented in the NMR lab of the NCSR “Demokritos” where she gained experience and skills in advanced methodologies and NMR techniques, in NMR hardware (development of home-build NMR spectrometers) and in low temperature measuring devices and techniques. Since 1998 she has been working as a research collaborator of the NMR lab through National and European funded research projects.  Also, since 2002 she has been collaborating with the Technological Educational Institutions (TEI) of Athens and Piraeus as a lab assistant and as a teacher of Physics courses at the Dept. of Electronics Engineering, of TEI of Piraeus. She has co-authored 21 publications in peer-reviewed international journals.

Her scientific activities are focused on the development and application of advanced Nuclear Magnetic Resonance (NMR) methods in the study of flow dymamics and transport phenomena of liquids confined in nano-porous materials and the study of crystal and electronic properties of facet-engineered nanocatalysts. In recent years she has been involved in the application of NMR techniques in a variety of research activities, such as the study of magnetic nanofluids for biomedical, geological and industrial applications, of    photoelectrochemical cells, strongly coupled electron systems, new superconducting systems (MgB2 superconductor and electron-enriched derivatives systems, NaxCoO2 systems (0 <x <1)) and has also been involved in the development of a novel electromagnetic (EM) methodology for the exploitation of magnetic nanoparticles as magnetic nano-sensors for subsurface electromagnetic imaging of hydrocarbon reservoirs.
