General information

Dr. Kalthoum Riahi (1989) was born in Kairouan,Tunisia. She studied ‘Fundamental Physics’ at the ‘Higher School of Science and Technology of Hammam Sousse’ (Tunisia)

Then, she obtained her master degree’s (MSc) in Condensed material 'nanostructures' (2014) and her Doctoral degree (PhD) in November (2017) from the University of Sfax.

Recently she joined the Magnetic Detection and Imaging group (MD&I) as Postdoctoral researcher at the University of Twente, Netherlands.

Research interests

Diagnosis of sentinel lymph nodes (SLN) with magnetic nanoparticles.

The aim of this research is to optimize the grain size and the magnetic behavior of different magnetic nanoparticles in different environment using Superparamagnetic Quantifier (SPaQ).
