Nectaria received both the B.Sc. degree in Geology in 2000 and the M.Sc. degree in Geophysics in 2002, from the Aristotle University of Thessaloniki (A.U.Th.), Greece. In 2008, she obtained the Ph.D. degree in Engineering & Electronics from The University of Edinburgh, U.K.

She is currently a Research Scientist with the Department of Geophysics at A.U.Th., Greece. From 2013 to 2018 she worked for Sensors & Software Inc. in Canada in the area of ground penetrating radar (GPR) R&D, applications and scientific advancements. During her tenure, she was also engaged in outreach and collaborative projects. Her main research activity involves the development of GPR technologies and their application to geophysical/engineering problems ranging from environmental monitoring to non-destructive testing and archaeological prospection. Her areas of expertise include numerical modelling using the finite-difference time-domain (FDTD) method and the application of numerical modelling to GPR.

Dr. Diamanti is a member of the Society of Exploration Geophysicists and of the European Association of Geoscientists and Engineers. She serves as an Associate Editor for the Journal of Environmental & Engineering Geophysics (JEEG). She is the Chair of IWAGPR2025, the 13th International Workshop on Advanced Ground Penetrating Radar and is the author of numerous scientific publications and reports on GPR and other geophysical methods.
