The Fishman Laboratory in the Department of Stem Cell and Regenerative Biology at Harvard University is looking for an enthusiastic and highly experienced Research Assistant IV with an interest in developmental biology, genetics, and social behaviors. The Fishman Lab is interested in dissecting complex social behavior by using zebrafish as a model system.

The candidate will work closely with scientists in the lab reporting results to supervisor or other lab personnel. The candidate will assume a high level of responsibility for independent judgment concerning future experiments depending upon results.

The Juntti Lab at the University of Maryland is seeking a postdoctoral fellow to work in an HFSP-funded position to understand the neural circuitry of visual perception in cichlid fish. We work in a multi-lab collaborative team to understand the differences in visual circuits in comparison with zebrafish. This project will determine the stimuli that evoke behavior, and will use genetically-encoded calcium indicators to identify the responsive neurons. 

Our lab focuses on the control of social behavior, and we ultimately seek to link perception to behavior. We are a well-funded young lab using cutting-edge technologies in molecular genetics, neuroanatomy, pharmacology to make these links. We use the family of cichlid fish as our model system, as they exhibit complex social behaviors and are genetically tractable. We’re looking for a motivated candidate who will pursue independent research, working within a dynamic team of scientists.

Post-doctoral position available at ENS


A 2-3 years post-doctoral position is available at the ENS, Paris, to study the initiation and growth of cancer from a single cell in zebrafish. The idea is to use the optogenetic tools developed in the host lab to turn on one (or a few) oncogenes (or off some tumor suppressor genes) in single cells of a zebrafish larvea.  The probability of tumorigenesis will be measured and the genetic analysis of cancer developing cells vs non-cancer developing ones will be conducted.


For this project we are looking for a smart, independent and driven person with demonstrated experience in zebrafish: micro-injection, transgenesis, microscopic observations, ISH and genetic analyses.

Knowledge of image analysis (ImageJ) and computer programming (R, Matlab, LabView) favored.

The person will be paid a net post-doctoral salary of about 2800€ (depending on experience). 


Appropriate candidates should send their CV and three letters of recommendation to David Bensimon ( .

PhD Project - Nanomedicine & Molecular Biology Lab, Univesity of Pisa

Project Title: Nanotransducers in gene therapy

Supervisor: Vittoria Raffa

Application deadline: 29th May 2019

Project description:  The most significant genetic tool of the 21st century concerns targeted genome editing using engineered nucleases. Among these, the most commonly used is CRISPR/Cas9 technology that, by means of an RNA guide (g-RNA), recognizes specific genomic sequences and induces double strand breaks (DSBs). Despite its therapeutic potential, CRISPR/Cas9 system is considered not yet mature for clinical applications, because of potential off-target activity, e.g. unspecific cuts of the genomes. In this scenario, nanomedicine will be used to give both temporal and spatial control over gene editing to switch off gene expression at specific times in specific tissues. This technology would bring: i) improvement of safety; ii) treatment of multi-genic diseases; iii) non-viral delivery of editing components. From a scientific and technological point of view, accomplishment of these objectives will pave the way for new horizons and opportunities in the treatment of solid cancer tumors through the achievement of unmatched safety level for the development of effective genome therapeutics.

Laboratory of Angiogenesis and Redox Metabolism

Dept. of Biology, University of Padua, Italy

The laboratory of Prof. Massimo Santoro, Department of Biology at the University of Padua,

Italy, is offering an ERC-funded post-doctoral position to study blood flow signaling during

angiogenesis. Blood flow and mechanical stress have not been fully decoded within

aspects of cellular signaling during blood vessel development. As such, our goal is to

understand how blood flow regulates vascular development and homeostasis using genetic

approaches along with advanced molecular and proteomic techniques. This project focuses

on using genetically encoded metabolic sensor, DNA editing knock-out/in techniques, and

in vivo angiogenesis models. The Santoro lab currently holds extensive experience in

biochemistry as well as the genetic, molecular, and cellular biology of endothelial and mural

cells in different vertebrate animal models and in human primary cells (1). The laboratory

contains zebrafish and mouse animal facility, advanced stereo/confocal/light sheet

microscopy equipment, advanced gene-editing techniques, and metabolic core facilities.

The candidate must be highly motivated, enthusiastic, and an efficient researcher with a

PhD in a relevant discipline. The applicant must be capable of working in a team as well as

independently. Excellent communication skills both spoken and written English are required.

We offer a dynamic work environment in a stimulating scientific surrounding with a young,

enthusiastic, motivated team along the opportunity to contribute to high-impact projects. We

offer a strong competitive salary as well as contributions to health and retirement funds.


Please send your CV, letter of motivation, and the contact information of at least two referees
