Ecologist and ecotoxicologist, Céline Pélosi is working on the effects of human activities on soil organisms and the functions they perform. She is particularly interested in the sensitivity of earthworm and enchytrid populations and communities to environmental factors (humidity, temperature, agricultural practices including tillage, pesticide use, organic matter inputs, etc.) and their functional complementarity (soil structure, water flow regulation, organic matter degradation) in systems that are more or less disturbed.

Her work addresses issues related to the ecological intensification of agrosystems, climate change, and the preservation of natural resources (soils, biodiversity, water). Soil organisms are used as indicators of the vulnerability and adaptive capacity of agricultural systems, but also as agroecological levers for more sustainable systems.
