Main interests

In every animal embryo, stem cells are required for the development, growth and regeneration of tissues and organs. At some point, the stem cells have done their job and must disappear. In fact, in adult animals only a few stem cells are still present.
However if unnecessary stem cells are left behind, malignant tumors can develop from them, in contrast if they disappear prematurely developmental defects can occur.

One and half orangesOur group uses the fruit fly Drosophila melanogaster as a model to study the mechanisms that regulate stem cell proliferation and fate during development. We are mainly focused in how temporal cues regulate the proliferation and fate of neural stem cells and their daughter cells. We are also studying how metabolism and nutrition affect stem cells and consequently animal development.

The understanding of how stem cells are temporally regulated and how they are influenced by external signals is crucial for the understanding of many developmental diseases, tumors and for their use in regenerative medicine.

1 Postdoctoral Fellow

1 ERC funded position for a postdoctoral fellow is currently open for a highly motivated candidate to join the Proliferation and Fate Regulation of Stem Cells Lab @ CEDOC-NOVA Medical School in Lisbon.

The research project aims to study how neural and adult stem cell fate is regulated by transcriptional networks and metabolism using the fruit fly as a model. The project includes state of the art methodologies, access to dedicated equipment and an interactive team with international collaborations.

Applications start on May 1st and will continue until the position is filled.

To apply, send one single PDF file including CV, cover letter and the name of three referees to Dr. Catarina Homem (catarina.homem(at)

- 2 Postdoctoral positions

2 ERC funded positions for postdoctoral fellows are currently open for a highly motivated candidates to join the Proliferation and Fate Regulation of Stem Cells Lab.

The positions are initially funded for one year, with possibilities of extension until the end of the project. Applications start on September 1st and will continue until the positions are filled.

Position 1 - The research project aims to study how stem cells are regulated by metabolism and nutrition using the fruit fly as a model.
Position 2 – Ideally for researchers with a bioinformatic background. The research project aims to do extensive bioinformatic analysis of large sequencing data sets.

To apply, send one single PDF file including CV, cover letter and the name of three referees to Dr. Catarina Homem (catarina.homem(at)
