Here is what you should do if you're interested in joining our group


Two fully funded positions

Two fully funded metabolomics/bioinformatics positions aiming at understanding the mechanisms underlying microbiome-brain interactions in Drosophila


We invite applications to join the behavior and metabolism laboratory (Ribeiro lab) at the Champalimaud Centre for the Unknown. We aim at using state of the art metabolomics and genomics approaches to identify how nutrients and the microbiome alter brain function. Recent research has highlighted the importance of nutrients and the gut microbiome in controlling physiology and behavior. How nutrients and gut microbes influence brain function to alter behavior is currently one of the big mysteries in biology. We have recently shown that two specific gut bacteria species alter feeding decisions in the powerful genetic model organism Drosophila melanogaster (Leitão-Gonçalves et al., 2017). We are now focusing on identifying the mechanisms by which nutrition and the microbiome alter the host brain to change behavior.

 We aim at filling two positions:

 1) A fully funded postdoctoral position

You will participate in an interdisciplinary, collaborative project between the Ribeiro lab and a leading metabolomics lab in the UK. We aim at establishing and using metabolomics and fluxomics approaches to identify the metabolites by which gut microbes act on the brain to influence the behavior of the host. The position involves using state-of-the-art metabolomics approaches, automated, quantitative behavioral assays, and other cutting-edge molecular and circuit neuroscience approaches to identify the mechanisms by which gut bacteria influence brain function.


2) A fully funded bioinformatician position (postdoctoral level)

You will participate in an interdisciplinary, collaborative project between the Ribeiro lab and leading metabolomics, fluxomics and genomics labs. We aim at establishing and using metabolomics, fluxomics, and transcriptomics approaches to identify the metabolites and transcriptional programs by which microorganisms act on the brain to influence specific appetites of the host. The position involves using state-of-the-art bioinformatics and data analysis approaches to probe metabolomics and transcriptomics datasets and identify the mechanisms by which nutrients and the microbiome influence brain function.

We are looking for highly motivated candidates with either a strong background in using molecular or metabolic approaches to attain mechanistic insights into complex biological processes such as metabolism or neuronal function (Position 1) or a strong bioinformatics background with either experience in the analysis of RNAseq or metabolomics datasets (Position 2). For Position 2, candidates with a strong biostatistics background and experience in mining large biological datasets will also be considered. Additional experience in Drosophila neuroscience, metabolism research, and microbe-host interactions are considered a plus. We strongly value team spirit and a positive and empowering work environment. You can find more information at: or inquire directly at

Candidates are encouraged to send applications (cover letter, CV, and contact information of 3 references) to and include “Postdoc or Bioinformatician Ribeiro lab 2019” in the subject line. Recommended application deadline is 20 February 2019. Reviewing of applications will start immediately until the position is filled. Openings are available immediately and the positions are fully funded until at least the end of 2021.
