Open Positions

The EPFL

The Ecole Polytechnique Fédérale de Lausanne (EPFL) is one of the most dynamic university campuses in Europe and ranks among the top 20 universities worldwide. The EPFL employs 6,000 people supporting the three main missions of the institutions: education, research and innovation. The EPFL campus offers an exceptional working environment at the heart of a community of 16,000 people, including over 10,000 students and 3,500 researchers from 120 different countries.

DCI

The Dubochet Center for Imaging (DCI) is a joint initiative of the EPFL, the University of Lausanne and the University of Geneva. It will be inaugurated with two Titan Krios G4 and one Glacios cryo-electron microscopes, all equipped with Falcon-IV detectors. The Titans will feature Cold-FEG electron sources, and one Titan will have a SelectrisX energy filter. The instruments will run under high automation. Further instruments for the DCI will follow. 

The DCI will have as partner site the CryoGEnic cryo-EM facility at the University of Geneva. In addition, the DCI will closely interact with the EMF cryo-EM facility of the University of Lausanne and the BioEMCIME electron microscopy facilities of the EPFL.

The DCI will use frontier cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET) to contribute to life sciences research in the Lemanic region. The DCI will expand its cryo-EM and cryo-ET studies with correlative light and electron microscopy (CLEM), correlative serial block-face scanning electron microscopy or FIB-SEM, and advanced levels of sample preparation and data analysis. The DCI will train the next generation of structural biologists and serve as platform to host workshops and seminars. It will strive to implement the latest developments in the areas of hardware and software.

The DCi will contribute to the [email protected] initiative, and provide cryo-EM analysis to the thriving life sciences research landscape in Lausanne, Geneva, and beyond.

LBEM

Our Laboratory of Biological Electron Microscopy (LBEM) in the Physics Institute of the Basic Sciences division at the EPFL is headed by Henning Stahlberg. The LBEM will setup its own electron microscopes, which will be primarily dedicated to method development. The LBEM will be a client to the services of the DCI, so that the above listed instruments of the DCI are equally accessible to us. The lab language is English, while the city of Lausanne is in the French-speaking part of Switzerland.  

The LBEM is affiliated with the following graduate groups:

EDPY
(Physics)

EDMS
(Molecular Life Sciences)
EDNE
(Neurosciences)

 

We have the following openings at the LBEM:

We have a postdoc opening in our group LBEM at the EPFL in Lausanne, Switzerland, in the area of method development for coherent electron diffractive imaging.

The project aims to develop a system that can determine the structure of frozen hydrated proteins with a cryo-transmission electron microscope, using a high-speed hybrid pixel detector camera and diffractive imaging approaches. Proteins will be frozen in thin, free-standing ice layers as single particles, similarly as used for single particle cryo-EM. However, data will be collected with a probe Cs corrected 300kV Titan Krios cryo-EM instrument in diffraction mode, using a prototype high-speed hybrid pixel detector camera. The project involves development of data collection schemes on the electron microscope, collecting diffractive data at very high frame rates, developing and applying online pre-processing to the data, and developing structure reconstruction methods.

Your profile :
Candidates should have a Ph.D. in Physics, Electrical Engineering, Computer Sciences, or related disciplines, and should have expertise in electron microscopy.

A PhD student position is available in the Stahlberg laboratory to develop methods in Coherent Electron Diffractive Imaging (CEDI) to study frozen hydrated biological specimens. CEDI is a method that uses a high-end cryo-electron microscope to illuminate a frozen cryo-EM protein sample with a convergent but slightly defocussed electron beam. An aberration corrector in the illumination system of the electron microscope will allow to maintain coherence in the illumination despite the high angle of beam convergence. This beam will traverse the frozen cryo sample and phase-contrasted electron diffraction patterns of the sample will be recorded with a high-speed hybrid pixel detector camera. These patterns will be computationally evaluated with iterative algorithms in order to reconstruct the electron illumination wavefront and the object wavefront. The latter corresponds to the projection image of the specimen. This method will be automated to be applied to a multitude of frozen protein samples, and the ensemble of recorded patterns will be evaluated to obtain the high-resolution 3D structure of the biological protein. 

This project will utilize a prototype frontier cryo-electron microscope that will be installed in our laboratory. It will involve advanced electron microscopy optics, aberration correction, and phase contrast diffractive imaging. It will also involve the application of the method to study the 3D structure of an important membrane protein by cryo-EM. 

The candidate for this PhD position should hold a Master’s degree in Physics, Electrical Engineering, or a related field (in exceptional cases, a Bachelor’s degree will also be accepted). The lab language is English. The candidate must be accepted by the doctoral school in Physics.

For more information, please contact Henning Stahlberg.

A PhD student position is available in the Stahlberg laboratory to contribute to the development of advanced methods in automated high-resolution structure determination of biological macromolecules by cryo-electron microscopy. The laboratory will setup a frontier cryo-EM instrument in the basement of the Cubotron building. This instrument will be used in to perform real-space imaging and also reciprocal-space electron diffraction data collection. The automated control of the electron beam in diffraction mode in the electron microscope has to be developed. The beam shall expose the sample at various locations, but in synchronization with a high-speed camera that collects images and diffraction patterns at a speed of several thousand frames per second. Data will be recorded at very high speed and very large volumes, so that the data have to be processed in real time to extract the structural information before the noisy data are deleted. 

This project will be at the interface between physics, electronic engineering, mathematics and computer sciences. It will involve collaborations with several other laboratories on campus and internationally.  

The candidate for this PhD position should hold a Master’s degree in Physics, Electrical Engineering, Computer Sciences, Mathematics, or a related field (in exceptional cases, a Bachelor’s degree will also be accepted). The lab language is English. The candidate must be accepted by the doctoral school in Physics.
