Open Positions

PhD / Postdoc Positions

We are looking for highly motivated scientists with a degree in natural sciences to join our young and growing team as PhD student or postdoc. 

The positions are immediately available at the Department of Medical Biochemistry & Molecular Biology and Center for Molecular Signaling (PZMS) at Saarland University, Homburg, Germany, in the research group of Prof. Bianca Schrul.

Our group is interested in the biogenesis and function of lipid droplets. These subcellular organelles dynamically balance the influx, storage and consumption of neutral lipids in nearly all cells of our body and are therefore central hubs in lipid metabolism. Lipid droplets are implicated in a range of human pathologies including hallmark diseases of our modern society such as obesity, diabetes, hepatic steatosis and cardiovascular disorders. However, the molecular mechanisms underlying lipid droplet biogenesis and function as well as pathologic aberrations in these processes remain largely unknown. 

Projects in our lab address the following questions: 

  • What are the molecular mechanisms underlying protein targeting to and insertion into the membrane of lipid droplets?

  • Which physicochemical membrane properties drive protein partitioning to lipid droplets?

  • How is lipid droplet biogenesis from the endoplasmic reticulum membrane regulated?


  • How do lipid droplets communicate with other lipid metabolizing organelles to adapt to metabolic changes? 

We employ a range of biochemical and cell biological techniques including in vitro reconstitution experiments, protein-interaction studies, organelle / protein isolations, CRISPR/Cas9 genome editing, RNA interference, quantitative proteomics & lipidomics analyses as well as advanced fluorescence microscopy. We have established close interdisciplinary collaborations in which we integrate our expertise with molecular dynamics simulations, microfluidics, and EPR spectroscopy.

Qualification profile: 

  • We are looking for highly motivated scientists with the following qualifications:


  • For a PhD student position: M.Sc. degree (or equivalent) in Biochemistry, Molecular Biology, Biophysics or a related discipline 

  • For a postdoc position: PhD degree (or equivalent) in Biochemistry, Molecular Biology, Biophysics or a related discipline 

  • Strong interest in basic biochemical and cell biological research


  • Excellent communication skills and strong team spirit

  • Interest in learning / expertise in biophysical approaches to study membrane protein structures & dynamics and/or organelle properties would be a plus

  • Fluent English (oral and written) is essential

  • German language skills are desired 

What we offer: 

  • Our young research team is integrated in an interdisciplinary and diverse research environment offering state-of-the-art technology and excellent scientific exchange.

  • Further training opportunities are provided by Saarland University´s Graduate Centre GradUS. 

  • Modern lab space with excellent infrastructure and core facilities (advanced light microscopy, mass spectrometry, etc.) in a newly constructed research building (PZMS).

The positions are immediately available.

Please send your application including a cover letter stating your motivation to join our lab and your research interests, a CV, degree certificates and contacts for two references as one PDF file via e-mail to Bianca Schrul.
