GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult.

Our latest work on causal models for this is out yesterday:

A short🧵:
Causal modelling of gene effects from regulators to programs to traits - Nature
Approaches combining genetic association and Perturb-seq data that link genetic variants to functional programs to traits are described.

We set out to investigate polygenic footprints of altitude adaptation in a moth species, but instead we uncovered a major selective sweep at genes often associated with insecticide resistance @prrnhd.bsky.social @schifanoalexandre.bsky.social @mgda76.bsky.social @cbgpmontpellier.bsky.social
A major selective sweep likely linked to insecticide resistance identified along altitudinal gradients in the pine processionary moth https://www.biorxiv.org/content/10.1101/2025.11.24.690095v1

In 2020, O Gaggiotti, J Goudet and I showed that Qst-Fst comparison was uncalibrated with high population structure.

During her PhD with us, Isa do O developed LogAV: a method that accounts for any population structure while testing for local adaptation :

A method for identifying local adaptation in structured populations
Species occupy diverse, heterogeneous environments, which expose populations to spatially varied selective pressures. Populations in different environments can diverge due to local adaptation. However...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants
