Postdoc position available

Starting date: Spring 2019

A postdoctoral position studying radial plant growth is available in the group of Thomas Greb at the Centre for Organismal Studies (COS) of Heidelberg University, Germany.

Our group investigates the process of radial growth and cambium regulation as a model for elucidating developmental principles focussing on intra- and intercellular communication. In the context of an ERC project, it is envisaged that the successful applicant will address the fundamental question of how cell identities are reprogrammed during postembryonic growth processes using biochemical, molecular and/or computational methods. For more information on the project or the general setup, please view our website pages ( or contact Thomas Greb directly.

Research at the Centre for Organismal Studies in Heidelberg is dedicated to study organismic biology from the basic molecular principles to cell biology, developmental biology and physiology both in plants and in animals at all organisational levels. The institute is fully embedded into the Life Science campus of Heidelberg University and access to state-of-the-art imaging, proteomics and genomics platforms is assured.

Successful applicants will be highly motivated, have outstanding communication skills, be capable of working independently in a goaloriented manner and have published (or be close to publishing) in major international journals. Experience in some or all of the following disciplines is desirable: plant development, genetics, histology, molecular biology, cell biology and transcriptomics. To qualify for the position applicants should have a PhD degree or equivalent obtained in a related field, preferably no longer than three years ago.

Interested candidates are encouraged to send an email including a cover letter describing their motivation, CV and contact details for two referees to Thomas Greb ( Reviewing of applications will be continued until a suitable candidate is found.

The University of Heidelberg offers the positions of a


PhD student (TV-L E13, 60%).


Location: Centre for Organismal Studies (COS)                          Starting date: Spring/Summer 2019


Project: The proposed project is designed to address a fundamental question of plant research: How is co-translational imprinting of the proteome affecting proteostasis and protein translation under diverse abiotic stresses to achieve acclimative growth responses?

N-terminal protein acetylation occurs at the ribosome of eukaryotes and affects more than 80% of cytosolic proteins in humans and plants. Despite the prevalence of this imprinting mechanism on the plant proteome, we know only little about its contribution to protein function.

We recently demonstrated that N-terminal protein acetylation is dynamically regulated by the stress-hormone abscisic acid, which decreases transcription and stability of the ribosome-associated N-terminal acetyltransferase complex A (NatA). Down-regulation of NatA activity in genetically engineered plants causes sensitivity towards abiotic and biotic stresses and constitutively activates the abscisic acid response 1, 2.

This project aims to elucidate the function of N-terminal protein acetylation for stress-induced regulation of protein turnover. A unique feature of our research team is the combined expertise on profiling of stress-induced translation, co-translational modifications of proteins, and protein stability. We will apply this expertise to unravel how abscisic acid affects proteasome-dependent destruction of NatA substrates. Furthermore, we will test the importance of candidate E3 ubiquitin ligases for specific recognition of N-terminally acetylated proteins (N-degrons).


Collaboration Partners: The project offers stimulating interactions and training opportunities within the framework of the Heidelberg Biosciences International Graduate School and all groups at COS. Strong connections to research groups in France (CNRS/University of Paris-Saclay) and United Kingdom (University of Birmingham) support the project.


Profile of candidate’s qualifications: We look for highly motivated young scientists with interest in molecular genetics and cellular regulation. Practical experience in molecular biology, biochemistry or cell biology of plants will be of benefit. The applicants should hold a M.Sc. in Biology, Biochemistry or other relevant subjects. Successful acceptance at the Heidelberg Biosciences International Graduate School is expected for the PhD student.

The University of Heidelberg is an equal opportunity employer.


Profile of the host lab: The project is offered by the department of Plant Molecular Biology (, which has a long-standing record to successfully graduated PhD students and a leading expertise in co-translation modification of proteins and the stress-induced regulation of translation in plants.

The Developmental Biology Group (Prof. I. Lohmann) at the Centre for Organismal Studies (COS) in Heidelberg, Germany is looking for

to study stem cell behaviour in the Drosophila testis.

The Lohmann lab ( works on elucidating the role of HOX transcription factors in defining cell fate using Drosophila as a model. We are located at the Centre for Organismal Studies (COS) at the University of Heidelberg, Germany and part of the collaborative research network SFB873 “Maintenance and Differentiation of Stem Cells in Development and Disease” (https://www.cos.uni-
We now seek for enthusiastic new colleagues to analyze the interplay between germline stem cells and their support cells under homeostatic and compromised cellular conditions. In particular, the project aims at identifying pathways monitoring genome integrity in stem cells and at uncovering the role of mitotic checkpoint components in monitoring asymmetric stem cell division in the male germline. The project builds on a wide array of advanced resources established in the Lohmann lab and will provide ample opportunity to implement and apply high-end techniques to investigate stem cells of the Drosophila male stem cell system at multiple scales.
The Heidelberg Molecular Life Science Community offers a vibrant stem cell research community, as well as state-of-the-art core facilities. You will have the opportunity to closely collaborate with highly recognized stem cell researchers of the SFB873 and beyond.

Successful candidates will have experience in confocal microscopy, advanced immunohistochemistry and possibly in Drosophila genetics and molecular biology. The ability to quickly integrate into an interdisciplinary team and work independently within an academic research environment is essential. The position is immediately available, the salary is according to TV-L regulations. Disabled persons with comparable skills will be preferentially considered.

The “Developmental Neurobiology” group, member of the Center for Organismal Studies (COS) and the Interdisciplinary Center for Neurosciences (IZN), is looking for a highly motivated

Postdoc (f/m)

We are interested in the molecular basis of axon growth during development and regeneration. The Postdoc-project will focus on the interactions of cell adhesion molecules with other types of proteins and the impact of these interactions on axon elongation and navigation. Substantial amounts of data have already been collected for several projects; the Postdoc is therefore expected to complete and publish these studies. In addition to these basic research projects, also a new translational project could be started aiming at the improvement of axon regeneration. We are looking for a self-motivated person with a background in molecular and cellular biology, ideally in neurosciences.

We are a small but well equipped group with access to all facilities on the campus. The position is available (for up to 2 years) from 1st of April on (also a later start is possible); please send your applications until 10th of March. Payment will be according to German TV-L13 (full time; can be split). Please send your CV, relevant certificates, and a short letter of motivation (all documents as one pdf file) to G.E.Pollerberg@cos.uni-heidelberg. Preference will be given to equally qualified applicants with severe disabilities. For further inquiries, please do not hesitate to contact Elisabeth Pollerberg.
