Mobility project

Detecting genes under selection during the domestication of Mediterranean olive tree: towards association mapping studies for adaptive traits

The aim of my project is to better understand the domestication of the olive tree in order to facilitate association mapping studies. I will first infer the demographic history with a Bayesian approach of this crop using genetic data (RNA-seq and microsatellites) and secondly I will detect the genes that were under selection during the domestication process.

Biography & research interests

Interested in both archaeology and biology, I have always tried to combine these two topics in my research projects. During my PhD (2009-2012), I worked at the Institut de Recherche pour le Développement jointly with the Centre de Bio-Archéologie et d’Ecologie, both in Montpellier, France. The objective of my work was to understand the evolutionary history and biogeography of the date palm (Phoenix dactylifera L.) using a complementary approach of seed morphometrics applied to both current and archaeological samples and genetics.

After my PhD, I joined the group of Daniel Wegmann at the University of Fribourg in Switzerland (2013-2014) where I infered the past history of the date palm using a large genomic data set that we generated.

During my stay at Montpellier SupAgro, in the framework of my AgreenSkills fellowship, I worked on the genomic changes associated with olive domestication both in term of changes in protein coding genes and in gene expression. I am now a senior research scientist leading the date palm genome project at New York University Abu Dhabi, in the United Arab Emirates.
