Julien Devilliers

PhD student, my main interests are the action of selective pressure at the different scales: from the protein (molecular biology/biophysics/biochemistry), to behaviour (ethology/ecology/evolutionnary biology).

Entomologist, I am using different insect models (mosquitoes, butterflies, cockroaches) to study their evolution under various selective pressures. While natural selection is visible at the individual level and mesure as survival and reproductive success (fitness), action of mutations at the genetic level trigger the adaptation abilities essential in the currrent global warming context. Genetic and behavioural scales are thus complementary to understand how gene mutations can tune a protein function and modify the fitness of an individual.

Adept at multidisciplinary work, my various projects allowed me to combine ecology, evolution, molecular biology, genetics, biophysics, bioinformatics and to work with museum collections.
