Postdoc position in Molecular Biology & Biophysics in Zürich

Studierende finden an der ETH Zürich ein Umfeld, das eigenständiges Denken fördert, Forschende ein Klima, das zu Spitzenleistungen inspiriert.


100%, Zurich, fixed-term

The Wieczorek Lab at the Institute of Molecular Biology & Biophysics at ETH Zurich investigates the physical principles underlying the self-assembly of complex intracellular structures from biomolecules. The group uses the microtubule cytoskeleton as a model system. We apply state-of-the-art methods in structural biology, in vitro biochemical reconstitutions, and single molecule biophysics to understand how diverse multi-microtubule assemblies form from a common tubulin “building block”. The results of our work are important for understanding the molecular basis of diseases such as cancer and neurodegeneration, which are often directly linked to defects in microtubule network assembly.

Project background

Previously, we solved the structure of the gamma-tubulin ring complex (gamma-TuRC), a huge multiprotein assembly proposed to nucleate and organize microtubules in cells (Wieczorek, Urnavicius et al. Cell (2019)). We are broadly interested in exploring the following open questions:

1) How does the gamma-TuRC regulate microtubule architecture?
2) How do gamma-TuRC co-factors interact with and regulate the various biochemical functions of the complex?
3) How are various microtubule networks properly established and regulated by the gamma-TuRC in conjunction with tubulin and other microtubule-associated proteins?

You will have the opportunity to explore these and other fundamental cell biological questions as the basis of their postdoc project in the group. 

The group has access to state-of-the-art electron microscopy instrumentation, including FEI Vitrobots and related grid preparation facilities and three Titan Krios microscopes, all hosted and maintained at ETH Zurich’s imaging facility, ScopeM. Appropriate computational resources are also readily available within the group and through a central computational cluster at ETH Zurich.

This is a fully funded position for a maximum of 4 years with an anticipated start date of January 1st, 2023 (negotiable). Further project details will be discussed during the interview.

Job description

We are looking for an enthusiastic and highly-motivated individual to investigate how microtubules self-assemble. You will develop cutting-edge assays for determining structural snapshots of microtubule assembly at near-atomic resolution.

Your profile
  • Structural biology background with hands-on experience in cryo-EM sample preparation, data collection, image processing (using e.g. RELION, cryoSPARC) and model building (using e.g. COOT, Phenix)
  • Experience developing custom scripts in e.g. Python for data/image processing, including using deep learning libraries, are a plus
  • A PhD degree in structural biology, biochemistry, biophysics, or other disciplines related to the position is required
  • Experience with basic molecular biology, cell culturing, and/or protein purification methods are a plus
  • Curiosity about the inner workings of the cell and a passion for basic science
  • The writing of scientific papers and active participation in internal meetings and in international conferences will require a good knowledge of English
