Anaïs Cario

Anaïs Cario is a Research Fellow at the Centre National de la Recherche Scientifique (CNRS), currently employed at the Institute of Condensed Matter Chemistry of Bordeaux (UMR 5026) since 2021. She completed her doctoral thesis in Earth Sciences - Microbiology at the École Normale Supérieure de Lyon in 2013, focusing on adaptations to life under high hydrostatic pressure in piezophilic microorganisms, particularly Thermococcus barophilus.

Her research interests span extreme microbiology, high-pressure environments, microfluidics applications, astrobiology, and deep-sea microbial ecosystems. Cario specializes in developing microfluidic tools to study extremophiles under conditions simulating deep-sea vents and subsurface environments. Her work bridges fundamental research on microbial adaptation with practical applications in CO2 geological storage, hydrogen metabolism, and prebiotic chemistry.

Analysis of her recent publications (2024-2025) reveals a strong focus on microfluidic approaches for studying deep-sea environments, with particular emphasis on prebiotic chemistry simulations, hydrogen metabolism in subsurface environments, and nanomineral production by microorganisms. Her research increasingly connects fundamental microbiology with energy transition applications, especially regarding geological storage and hydrogen production.

Anaïs Cario actively participates in thesis committees, having served on juries for doctoral students working on CO2 valorization through hydrogenotrophic methanogenesis, Thermococcales biomineralization, and hyperbaric techniques for deep-sea microorganism studies. Her collaborative network includes researchers from multiple French institutions, with Samuel Marre appearing as a frequent co-investigator on numerous projects.

She is a key contributor to the HOTDOG project and collaborates extensively with teams studying deep-sea microbial ecosystems, employing advanced microfluidic tools to simulate extreme environmental conditions at laboratory scale. Her work with the TWINN2SET project focuses on deep subsurface microbial life in the context of energy transition.
