Object: Postdoc Position Building a phylogenetic model for horizontal transfers of transposable elements A postdoctoral position (24 months) is available to work at EGCE (Gif-sur-Yvette, France, CNRS / Université Paris-Saclay) from January 2026. Transposable elements (TEs) are repetitive DNA sequences capable of promoting their own mobility. They are widespread across the tree of life and often represent a substantial fraction of eukaryotic genomes. Beyond their ability to invade genomes, TEs are frequently reported to undergo horizontal transfer, enabling their colonization of new hosts. However, understanding and predicting how horizontal transfers shape the distribution of TEs among species is far from straightforward. In particular, estimates of transfer rates based on documented cases are both biased and approximate, since transfers occurring close to speciation events are virtually undetectable. This project aims to develop explicit phylogenetic models of TE evolution that incorporate horizontal transfers, and to use these models to obtain statistical estimates of key evolutionary dynamics of TE families across species (e.g., horizontal transfer and extinction rates). The postdoctoral project will focus on exploring the impact of horizontal transfers on the distribution of TE presence/absence among related species, using statistical and/or computational approaches.
Context The position will be part of a 4-year collaborative project funded by the French National Agency (ANR). The research consortium gathers two departments (from Paris-Saclay university and from Université Lyon 1), and involves 7 Pls and 5 postdocs and PhD students devoted to distinct workpackages of the project. The postdoc will be based at EGCE, which is part of the Institute for Ecology and Evolution (IDEEV). The institute offers an exciting and active scientific life, it is located on the new research campus of Paris-Saclay, 35 km south of Paris. Relevant references Gilbert C et al. 2018.

Skills in statistics, programming, bio-informatics, and phylogenetic models will be appreciated.

This method is strongly inspired by previous by O Ovaskainen and J Merila :
academic.oup.com/genetics/art...
The key differences are that we use a different test statistics and a quite generally applicable estimator of co-ancestry developed by J Goudet and B Weir:
journals.plos.org/plosgenetics...
We show in the paper that doing so results in calibrated tests of neutrality, even in the face of highly structured scenario, contrary to classical Qst-Fst comparison. 🎉
The clever trick is since both estimates (using between- or within-population co-ancestry) refer to the same ancestral VA, they should be equal under neutrality.
LogAV thus compare these estimates as the Log-ratio of Ancestral Variances (hence the name) to 0 (the expectation under neutrality).
Instead of summarising co-ancestry with a global Qst, or Fst, index, LogAV uses the full, carefully designed, matrices of between- and within-population co-ancestry to refer to the same ancestral additive genetic variance.
As such, it fully accounts for the actual population structure.
