PhD position: Sub-micron structural assessment of hybrid biopolymer networks by NMR and MRI

This PhD project is a part of a large collaborative Industrial Partnership Programme between AMOLF, Wageningen University, University of Amsterdam and Unilever Research, entitled Hybrid soft materials: from physical mechanisms to designer products. The overall goal of the programme is to understand the physics of the assembly and visco-elastic properties of hybrid networks, consisting of mixtures of stiff and soft elements, which leads to the rich and complex multiscale physics that characterize real food products. The understanding of the design principles and the relation between the molecular, microscopic and mechanical properties of hybrid networks will be used in the design of new, improved systems, in particular new food products.

Job description
The PhD student will develop, validate and implement magnetic resonance approaches (NMR and MRI) for non-invasive assessment of hybrid biopolymer network formation and degradation under dynamic conditions such as stress and shear. Velocimetric measurements under shear (RheoMRI) will be combined with nanoprobe (PFGNMR) diffusometry to provide a view on biopolymer network formation/degradation at sub-µm scale.

The candidate should have an MSc degree (or the equivalent) in Physics or Physical Chemistry, with a strong background in NMR techniques applied to structure-function relationships of materials. Experience with food materials and/or MRI would be an advantage. Good communication skills in English are required.

Conditions of employment
When fulfilling a PhD position at the FOM Foundation, you will get the status of junior scientist. You will have an employee status and can participate in all the employee benefits FOM offers. You will get a contract for four years. A training programme is part of the agreement.
