We aim to improve the treatment of Tuberculosis, by visualising and understanding how proteins work within their cellular environment in health and disease. Will you help us achieve this goal? Then join the Nanoscopy Division in the Maastricht Multimodal Molecular Imaging Institute (M4I)!
Job description

Tuberculosis (TB) is an infectious disease caused by the bacillus Mycobacterium Tuberculosis. Even though TB is curable, about one and a half million people succumb to it every year. Current treatments are long and with side effects: the need for new antibiotics and vaccines is obvious.

We aim to understand how gene products or proteins work within their cellular environment in health and disease. Our institute houses a state of the art cryo-Light Microscopy/Electron Microscopy correlative workflow from cellular localization, milling with focused ion beam (FIB-SEM), down to cryo-electron tomography, subvolume averaging and image processing to study how these nano-machines work under native conditions.

We seek a talented Postdoctoral candidate to join our interdisciplinary team. Our biology research focuses on unraveling, controlling and tempering the pathogenicity of Mycobacterium tuberculosis at a molecular level. The applicant will apply in situ structural biology to understand these nano-machines within its native context of the infected cell. The important work in biochemistry and single particle analysis performed in our group will support the candidate´s project. The candidate will work within a team of academic investigators and (industrial) engineers to research and develop a next generation Vitrojet device for optimal vitrification of cells together with some companies like our startup .
