Research

Current Research Topics

My research in evolutionary ecology aims to improve knowledge about the biology of diadromous fishes to provide guidelines for the conservation management of these species, which divide their life cycle between freshwater and marine environments.

I use various approaches at the individual and population levels based on field observations or experiments in the laboratory. My projects are based on population genetics and genomics approaches to understand the adaptation of living organisms to environmental changes. I focus mainly on European anadromous species that reproduce in freshwater and spend some time at sea: Atlantic salmon, sea trout, shads and lampreys.

My current projects address the following topics:

Effects of environmental changes, human-induced disturbances and management on the genetic diversity of anadromous fishes
Evolution of anadromy and parasitism in lampreys of the genus Lampetra
