Quentin Petitjean

Understanding how animals respond to a changing environment. Research in evolutionary ecotoxicology and ecophysiology at INRAE.

Evolutionary ecotoxicology & ecophysiology

Quentin Petitjean.

Understanding how animals respond to a changing environment.

I study how pollution, temperature and pathogens interact and why some individuals and populations cope better than others.

Ecotoxicology. Individual variation. Open science.

One environment. Different responses.

Research themes ↗
01 / MULTIPLE STRESSORS

Combined effects of environmental stressors

Understanding how contaminants, temperature and pathogens interact to affect organisms, from molecular responses to behaviour and survival.

02 / INDIVIDUAL VARIATION

How and Why individuals differ in their sensitivity

Investigating how sensitivity to environmental stress varies within and among populations, and the physiological and behavioural traits underlying these differences.

03 / WILD POLLINATORS

Wild bee diversity, health and pollination

Assessing how pesticides and their alternatives affect the health of different wild bee species, with consequences for bee diversity and pollination.
