Christine Dupuy

Christine Dupuy is a full Professor at La Rochelle University, affiliated with the CNRS/INSU - LIENSs Laboratory (UMR 7266). Her research focuses on Aquatic Ecology, Microbial Ecology, and Blue Carbon dynamics, particularly in coastal environments like marshes and intertidal zones.

• Deputy Director of LIENSs Laboratory (2020–present)
• Member of EMBRC-France (2018–2021)
• Coordinator of multiple national/international projects (ANR VASIREMI, BIOMIC, TETRAE, etc.)

Her research interests center on microbial trophic networks, planktonic-benthic coupling, and climate change impacts on coastal ecosystems. She uses innovative methodologies including ZooScan/ZooCAM imaging systems, stable isotope analysis, and biofilm mesocosm studies.

Her publication trends (135+ peer-reviewed papers) reveal a strong focus on:

• Microbial community responses to environmental changes
• Carbon cycling in temperate and tropical coastal systems
• Trophic interactions in anthropized marshes
• Blue Carbon assessment frameworks
• Long-term ecological monitoring (Bay of Biscay, Charente-Maritime)

She has served as:

• Expert for ANR CE32 (2018–2021)
• Member of CNU 67 (2007–2009, 2011–2019)
• Coordinator of educational programs (BIOSOUM, BIOEM diplomas)

Her laboratory (LIENSs) engages in regional and international collaborations through networks like Acclimaterra, NAIADES, and PEPR Faircarbon. Current projects include:

• ESA Blue Carbon Project (2024–2026)
• LIFE MARAISILIENCE (2024–2028)
• PPR RIOMAR (2023–2028)
