The scientific team
Dr Maeva Leitwein
A specialist in genomics and epigenomics, Maeva studies diversity, adaptation and the interactions between natural and domestic populations. She brings her research experience to questions of conservation and management.
Background
Coming from the academic world and originally from the Molène archipelago in Brittany, I am particularly interested in the use of genomic tools for biodiversity conservation.
My research mainly focuses on understanding and evaluating the evolutionary mechanisms that shape intra- and inter-population biodiversity at different time scales.
After a Master’s degree in marine biology, I specialised during my PhD in the use of genomics to assess the consequences of introducing domestic individuals into wild populations. During my post-doctorate in Canada, I used genomic and epigenomic tools to study the impact of fish farms on the genomic heritage and fitness of wild populations. These approaches helped me understand the evolutionary forces (positive or negative) that shape the genomic landscape of natural populations.
Back in France since 2021, I now study the effects of temperature, in the context of global warming, on sex determination in European sea bass. Alongside this, I study the effects of lineage mixing (ancestry) on the phenotype of individuals and the consequences for the adaptation of species to their environment.
Within LDgenX, I bring my expertise in genomics to answer conservation questions for better management of natural and domestic populations.
