Doctoral & Postdoctoral Positions in Computational Membrane Biophysics in Erlangen

 

Doctoral & Postdoctoral Positions in Computational Membrane Biophysics in Erlangen

Applications are invited for PhD positions/Postdoc/Senior Postdoc in our lab for theoretical and computational membrane biophysics at the Friedrich-Alexander University of Erlangen-Nürnberg, Germany.

Plasma membranes and in general biomembranes establish and maintain differences in composition between the cell or organelle interior and exterior. Biomembranes are the site for cell-cell recognition, they allow active and passive transport of material into and out of the cell, and they harbour proteins as initiators of signal transduction pathways.

Projects address the physico-chemical driving forces for the establishment of membrane domains within the immune cell plasma membrane, and their role for sensing of external signals by immune receptors and signal transduction, as well as membrane remodeling. The aim is to shed light on the cooperative action of proteins and lipids in shaping biomembrane structure.

Central questions for our research are

  • How are external signals sensed by immune cells, how do lipids contribute to signal transfer across the cell membrane, and how do lipids modulate immune cell activation?
  • What is the role of plasma membrane domains in immune cell activation?
  • Can we modulate or control immune cell function by cell membrane composition?

and more general

  • What are the physical driving forces for membrane domain formation?
  • How is domain formation linked to plasma membrane asymmetry?
  • How are plasma membrane asymmetry and biological membrane processes interlinked?

Applicants for doctoral positions:

Candidates should preferably hold a master degree in bio-/physics, theoretical/computational chemistry, life sciences or similar and a strong interest in interdisciplinary projects and collaborations to medical/immunology groups.

 

Postdoc applicants:

The successful applicant has a keen interest and strong skills in methods from statistical and computational physics, in particular atomistic and coarse-grained molecular dynamics simulations. The project involves close collaboration with immunology groups. The Postdoc will have the opportunity to participate in a research cluster studying the structure and function of immune domains.

Other requirements:

High level of English and good communication skills; effective team working.

Erlangen is a center for immunobiology with more than 70 groups focusing on immunological topics. In addition, since 2021, the University of Erlangen hosts a National High Performance Computing Center (hpc.fau.de) with a focus on atomistic simulations.

Interested candidates should send one pdf document containing a cover letter, CV, and certificates to

PhD Position in Biophysical Chemistry

Applications are invited for a PhD position in the research group of Professor Karin Hauser at the University of Konstanz. The project is dedicated to study molecular interaction mechanisms with infrared spectroscopy. We established an ATR-FTIR spectroscopic approach to study aggregation pathways of polyglutamine (polyQ) proteins by the controlled initiation of the aggregation process facilitating the structural characterization of intermediates in dependence of time. Expanded glutamine repeats are found in many neurodegenerative diseases, but molecular mechanisms leading to disease-related aggregates or preventing aggregation are not well understood. Focus of the project is the further development of the infrared spectroscopic approach and the analysis of molecular interactions between polyQ repeats and chaperones. PolyQ aggregation kinetics and pathways shall be analyzed in the presence of chaperones to get insights into molecular mechanisms of chaperone function.

PhD Position in Experimental Molecular Biophysics

Applications are invited for a PhD position in the research group of Professor Karin Hauser at the University of Konstanz. The project is dedicated to study protein folding dynamics by time-resolved infrared (IR) spectroscopy. In particular, a homebuilt IR spectrometer with a laser-excited temperature-jump will be used to monitor submillisecond structural dynamics. Focus of the project is the understanding of molecular mechanisms in the stabilization of protein structures. Model peptides with novel site-specific infrared probes will be applied to analyze structural dynamics on the basis of individual amino acids, thereby exploring backbone and side-chain dynamics separately.
We are looking for a highly motivated student who has successfully completed a master in (bio)physics or chemistry. The ideal candidate should have experience in spectroscopic techniques or laser spectroscopy or optics. Interest in biophysical research and interdisciplinary work is expected. Further requirements are the ability to work independently and in a team, as well as good English language proficiency.
The position is integrated in the Collaborative Research Center 969 “Chemical and Biological Principles of Cellular Proteostasis” (A2) and immediately available.
