I am a PhD student at the University of Montpellier, affiliated with ISEM, where my research explores the impact of human infrastructures, including dams, on aquatic ecosystems and biodiversity. My work focuses on the genetic structure of migratory fish populations, combining molecular biology and bioinformatics techniques. My aim is to understand the dynamics and gene flow between fish populations along the river. The goal is to provide a solid scientific foundation to understand and mitigate long-term impacts on aquatic biodiversity and the ecosystem services it supports.
