The Biozentrum of the University of Basel is one of the leading institutes worldwide for molecular and biomedical basic research and teaching. It is home to more than 30 research groups with scientists from over 40 countries. Research at the Biozentrum focuses on the areas of Cell Growth & Development, Infection Biology, Neurobiology, Structural Biology & Biophysics and Computational & Systems Biology. With its more than 500 employees, the Biozentrum is the largest department at the University of Basel's Faculty of Science.

The Abrahams group at the Center for Cellular Imaging and NanoAnalytics (C-CINA) of the Biozentrum studies 3D nanocrystals of proteins and smaller compounds, and semi-crystalline biological structures by electron diffraction. For measuring electron diffraction data, we use ultra-sensitive, radiation hard direct electron detectors based on the Timepix ASIC, which allow solving protein structures from a single 3D nanocrystal. Structures are solved using standard crystallographic procedures for data integration and phasing.

We study several biological systems in collaboration with research groups at the Biozentrum, at the Paul Scherrer Institute Laboratory of Biomolecular Research (PSI-LBR) and in international collaborations. Systems studied include membrane proteins, tubular structures and large, single protein complexes involved in protein quality control and breakdown. We have a fully equipped lab for protein production and purification and through close ties with the Paul Scherrer Institute (prof. Abrahams head PSI-LBR) access to synchrotron facilities and (in the near future) SwissFEL. At C-CINA, we operate a FEI Titan Krios, equipped with a Gatan GIF-LS and K2-Summit detector, a FEI Polara, equipped with another K2 Summit and a 512x512 Timepix electron diffraction detector, and a Talos Arctica with a 1024x1024 Timepix electron diffraction detector.

For supporting our efforts in method development and structure solution using electron diffraction data, we have a vacancy for a highly motivated postdoc.

Your responsibilities are

  • Optimising procedures for sample preparation for electron diffraction studies.
  • Developing optimal procedures for electron diffraction data collection using the rotation method.
  • Developing methods for measuring electron diffraction/scattering data of large molecular complexes.
  • Collaborate with biological research groups on structure determinations of protein nanocrystals, semi-crystalline single particles.

Your profile

Applicants should preferably have experience in cryo-EM data collection. But also if you are an expert protein crystallographer with hands-on expertise in data collection and methods development, you are invited to reply.

The primary language in the laboratory is English.

This position is funded for two years, an extension is possible.
