Louis Susset

Research Interests

Louis Susset investigates how antibiotic pollution and climate change stressors, such as heat waves, affect the structure and functioning of aquatic biofilms—microbial communities crucial for biodiversity and ecosystem processes. His research combines controlled microcosm experiments and in situ studies to explore how pharmaceutical pollutants interact with environmental changes.

Using metabolomics, metatranscriptomics, and other multi-omics approaches, he investigates how these combined stressors affect microbial communities at both molecular and phenotypic levels. His work aims to to identify ecological thresholds for regulation and management to protect periphyton biodiversity and functioning.

He is involved in the Pharm-ERA Doctoral Network, which aims to assess the impact of pharmaceutical micro-pollutants on microbial communities in terrestrial and aquatic ecosystems. By integrating chemical and microbiological contamination data, the project seeks to understand the links between pharmaceuticals, antimicrobial resistance, and ecosystem health, contributing to improved monitoring strategies and environmental risk assessments.
