Research interests

 

My research interests belong to the fields of microbial ecology and geomicrobiology. Studying the relationship between bacteria and their environment is of great interest since bacteria have colonized all ecosystems and play a key role in biogeochemical cycles; bacterial activity is the foundation of ecosystem functioning.

My PhD thesis focuses on the spore-forming bacteria and spore-like structures. As a first objective, we aimed to assess the possible use of spores for paleoecological studies, proposing a new powerful tool for the study of ecosystem history and the assessment of ecosystem health. We also investigated the possible use of spores as a biological marker for tracking antibiotic resistance genes (ARGs) in the environment. Because of its high dispersal rate and increased survival, the spores might represent key organisms for the persistence and dissemination of ARGs in the environment.
