Research Interests

My work is focused on the study of fundamental questions about adaptation to environmental stress. More precisely, I’m developing experimental designs with the model organism Tribolium castaneum (commonly known as the ‘red flour beetle’) in two main, and linked directions:

First, I want to highlight the genetic basis of adaptation to temperature and humidity in this coleopteran. This is done by using RNA-seq on populations which have been submitted to long term evolution in more or less hot/dry environments. We are able, with this kind of design to target candidate genes with differential expression across environments. Gene expression levels will be measured together with morphological traits and individual fitness in each environment. The plastic triggering of expression will be studied by measuring RNA levels in response to different environmental values.

The second part of my project is focused on clarifying the role of gene flow, via migration, on adaptation. More precisely, we expect gene flow to promote or slow adaptation depending on 1. The receiving population status (size, inbreeding level, etc...) 2. The origin of migrants (are they carrying good/bad alleles?) 3. The rate of migration.
