We always hope to grow the team with scientists and students who share our passion for high resolution microscopy of individual molecules, preparative mass spectrometry, and instrumentation development. Please be in touch to discuss opportunities in detail.
Postdoctoral Researchers
(1) PDRA position in analysis of glycans and glycoproteins adsorbed on surfaces by scanning probe microscopy. The position over 2 years in collaboration with the Struwe-group. The project includes working with the ESIBD and SPM equipment to develop methods in the analysis of individual complex biomolecules adsorbed on surfaces. Please contact Stephan Rauschenbach or Weston Struwe if you are interested in this post.
(2) Besides the currently open posts, we support applicants in preparing proposals for individual postgraduate research funding (e.g. ERC-Marie Curie Program, Humboldt program, Newton fellowship). Postdoctoral research projects can range over the entire spectrum of our scientific portfolio.
Please contact us with a short cv if you have interest in joining us as a postdoc.
DPhil (PhD)
We can offer a number of exciting projects for DPhil (PhD) studies.
(1) Cryo-TEM imaging of mass selected proteins. (Research Page)
Cryogenic electron microscopy (cryo-EM) is emerging as the dominating method for structure determination of proteins. However, the sample preparation is based on plunge freezing proteins in solution into thin ice layers, which limits contrast and scope of the sample preparation method as many proteins are not compatible with this preparation method. We are developing and applying and alternative method of cryo-EM sample preparation, which is based on preparative mass spectrometry to prepare samples without ice directly in vacuum.
(2) Imaging biopolymers by scanning probe microscopy.
Scanning probe microscope (STM: scanning tunneling microscopy, AFM: atomic force microscopy) can resolve molecular structure at the atomic level. We investigate molecules of complex structure and conformation adsorbed at a surface, brought there with ES-IBD. Important goal are the sequencing of peptides and glycans as well as the atomically resolved imaging of large molecules by non-contact AFM.
(3) Chemical reactions triggered by hyperthermal collisions of molecules and surfaces. (Research Page)
Energy is needed to make chemical reactions proceed. Usually this energy is supplied from thermal energy, sometimes from light or other excitations. The collision of ions with surfaces at hyperthermal energy represents a unique way of supplying that energy. In this project we use the unique capability of Electrospray ion beam deposition to tune the collision energy in the range between 1eV and several 100eV to trigger chemical reactions which otherwise cannot be observed. We will investigate the mechanochemical mechanism that proceeds in this type of reaction and explore its possibility to covalently modify surfaces with complex molecules.

(4) Development of novel electrospray ion beam deposition (ES-IBD) instrumentation
Electrospray ion beam deposition (ES-IBD) is the deposition of mass-selected molecular ion on surfaces in vacuum, whereby the energy of the molecular ion beam can be controlled. We develop a novel instrument based on advanced ion optics, which will allow us high selectivity (mass, mobility(shape)) while also have high beam intensity and control over the ionisation process.
