​Dr Najet Mahmoudi, PhD

Najet is the SANS2D instrument responsible within the Small-Angle Neutron Scattering Group​ at ISIS and focuses on developing capabilities and applications of SANS in life sciences.

She joined ISIS in 2016 as a SANS instrument scientist in the Large Scale Structures Group, and in 2019 she became the instrument responsible for SANS2D.

Najet graduated with an Engineer's and MSci degrees from the University of Carthage (Tunisia) and gained her PhD from the Biology and Chemistry Doctoral School at the University of Nantes (France), studying the impact of structure on the interfacial properties of self-assembled proteins. She then went on to do postdoctoral work in protein biophysical chemistry at the University of Fribourg (Adolphe Merkle Institute, Switzerland), Cambridge University (Cavendish Laboratory, Swiss National Science Foundation Fellowship) and the University of Lund (Physical Chemistry Department, Sweden).

She is interested in understanding the structural properties of biological soft matter systems such as protein complexes and hydrogels, and drug delivery systems like lipid nanoparticles. She works very collaboratively with colleagues in academia and industry and is particularly interested in combining in-situ investigation of dynamics and mechanical properties to SANS using techniques like dynamic light scattering and rheology (DLS-SANS and Rheo-SANS)5 and size-exclusion chromatography (SEC-SANS).
