A postdoctoral position is available in the laboratory of Dr Caroline Hill at the Francis Crick Institute (, which is a new world-class interdisciplinary biomedical Institute situated in central London.

Work in the Hill lab is focused on understanding how TGF-β superfamily signalling pathways function normally in early vertebrate development and in adult untransformed tissue culture cells, and how these signalling pathways are perturbed in cancer. We have been exploiting the very powerful combination of early vertebrate developmental systems (primarily zebrafish embryos), together with a variety of model tissue culture systems, and we use methodologies ranging from developmental and cell biology to computational modelling.

The Paridaen lab at ERIBA is currently looking for a highly motivated PhD student and post-doctoral researcher.

ERIBA (The European Research Institute for the Biology of Ageing) is a newly established institute at the University Medical Centre Groningen (UMCG). The mission of ERIBA is to better understand the molecular mechanisms that result in age-related decline and age-related diseases. We aim to develop novel strategies to prevent or combat age-related diseases and to provide evidence-based recommendations for healthy ageing. The research teams are working with different model systems and technology platforms and share their knowledge and expertise to accelerate discoveries. The ERIBA is housed in a new building and is part of the central UMCG campus in the vibrant University City Groningen in the north of the Netherlands. Groningen is a small (200,000 inhabitants), but vibrant city hosting over 25,000 students.

Stem cells act in developing and adult organisms to produce the proper number of specialized cells in the body. It is important that stem cells select an appropriate division mode to ensure proper development, maintenance and repair of tissues. In the Paridaen lab, we aim to understand the mechanisms underlying stem cell decisions in developing and ageing tissues. We employ single cell analyses techniques to study stem cell behaviour in the developing brain, using zebrafish and mouse as our model systems. In particular, we are interested in the role of fate-determining factors such as signalling pathways and subcellular structures in symmetric and asymmetric stem cell divisions.

PhD position in the mechanics of neuronal development


A 3-year funded PhD position is available at the Institut de Biologie Paris Seine to investigate the role of mechanical forces in the construction of a neuronal circuit in vivo.

During neuronal circuit formation, neurons move towards their final location while growing axons towards their target. While the biochemical guidance cues involved in neuronal migration and axon elongation are extensively studied, the contribution of mechanical forces in these processes remains largely unexplored in vivo

In the lab we address this question using the zebrafish olfactory circuit as a model system. Its location underneath the skin of the embryo makes it amenable to live imaging and mechanical perturbation. We already obtained imaging and functional data suggesting an important function for mechanical cues in the formation of the circuit: olfactory axons extend through the effect of extrinsic mechanical forces that drive the passive displacement of neuronal cell bodies away from their axon tips (Breau et al., Nat Comm, in press).  

The purpose of the PhD project is to further identify the origin and contribution of mechanical forces in the construction of the circuit, and the molecular mechanisms involved in force propagation and sensing. To achieve this goal, the student will use a pluridisciplinary strategy combining multiscale live imaging, genetic/optogenetic tools and physical approaches to measure and perturb forces in vivo. 

We are looking for a highly motivated student willing to join an interdisciplinary environment involving strong interactions between biologists and physicists.



- Master degree in cell/developmental biology or in biophysics 

- Strong interest towards interdisciplinary work


Additional beneficial skills:

- Experience with zebrafish 

- Skills in confocal, biphoton or light sheet microscopy

- Experience in image analysis (Image J, Matlab)


Starting date: between October 2017 and January 2018. To apply, please send your CV and references to Marie Breau, Institut de Biologie Paris Seine:

A PhD student position is available in the laboratory of Prof. Matthias Hammerschmidt at the Biocenter of the University of Cologne, Germany, to contribute to our ongoing research on bone development and homeostasis in the zebrafish. The project will focus on the vertebral column. One part will deal with the roles of different growth factors (retinoic acid, BMP, FGF, Wnt etc.) and their interconnection during spine development at larval stages, the other with mutants isolated during our in-house forward genetics displaying scoliosis in juvenile and adult fish / post metamorphosis. The causative recessive mutation of one of the scoliosis mutants has been resolved, requiring confirmation via CRISPR/Cas genetics, as well as further in-depth phenotypic analyses, including state of the art imaging technologies including multiphoton confocal microscopy and microCT.

PhD student position on zebrafish skin development, regeneration or carcinogenesis in Cologne, Germany

A second PhD student position is available in the laboratory of Prof. Matthias Hammerschmidt at the Biocenter of the University of Cologne, Germany, to contribute to our ongoing research on skin development, regeneration or carcinogenesis in the zebrafish. Using a combination of forward and reverse (CRISPR) genetics, transgenesis, pharmacogenetics, and in vivo imaging, we study different aspects of skin development, including cornification-like processes in epidermal appendages named breeding tubercles, as well as epithelial carcinogenesis and wound healing in the adult skin, including the formation and regression of scar tissue (see for instance, Richardson et al., Development 2016; Hatzold et al., eLife 2016). Our research is of high biomedical relevance, as several of our investigated genes are also implicated in human skin development, homeostasis or disease.

A postdoctoral fellow position is available for a creative and highly motivated scientist in the research group of Dr. Chris Hall in the Zebrafish Development and Disease Models Laboratory at the University of Auckland, to study macrophage activation during acute gouty inflammation.


Project description:

Acute gouty inflammation is the result of monosodium urate (MSU) crystal deposition in and around peripheral joints leading to activation of tissue-resident macrophages, neutrophil recruitment and acute joint inflammation. There is a clinical need for new anti-inflammatory treatments for gout as current therapies are non-specific and limited by potential drug toxicities, and gaps in therapeutic efficacy. The primary aim of this project is to leverage off a unique larval zebrafish model of MSU crystal-driven inflammation we have developed, to provide new insights into how macrophages are activated by MSU crystals and uncover new drugs to alleviate acute gouty inflammation.

Dr Hall’s research group has an established track record of exploiting the zebrafish model system to provide unique insights into innate immune cell function and as a drug discovery platform (see Astin et al., Methods Cell Biol 2017, Hall et al., Nature Communications 2014, Hall et al., Dis Model Mech 2014, Hall et al., Cell Metabolism 2013, Hall et al., Cell Stem Cell 2012, Hall et al., BMC Dev Biol 2007).


Position availability:

From 1st November 2017 (funded by a 3 year grant from the Health Research Council of New Zealand).


Applicant qualifications:

Candidates must have a PhD (ideally within the last 4 years) and show evidence of exceptional scientific contributions through publication in high impact journals, ideally in the fields of blood development and/or immunity. Candidates with experience in live cell imaging, standard and advanced cellular and molecular biology approaches, genetics, biochemistry, innate immunity and blood development will be viewed favourably. Although not essential, experience with the zebrafish model system and generating CRISPR mutants is desirable.
