Gabriela Salvadori

  • Post doc; PhD

About 

Gabriela Salvadori is a Postdoctoral Fellow at the Technology and Innovation Clinic (The Intervention Centre), Oslo University Hospital. Gabriela graduated with a DDS degree from the Federal University of Rio Grande do Sul, Brazil (2014), and later completed a Ph.D. in Oral Microbiology at the Faculty of Dentistry at UiO (2018). As a researcher in microbiology, she has made significant contributions to the field and has established protocols for cultivation and genetic modification of species from the genus Streptococcus. As a junior investigator, she received the prestigious Hatton Award from the International Association for Dental Research (IADR) and the Nordisk Odontogisk Förening for her work on quorum sensing systems in Streptococcus mitis and Streptococcus pneumoniae.

Passionate about staying connected with fellow researchers and staying updated on the latest advancements, Gabriela been actively participating in professional associations like the IADR and the Norwegian Society for Microbiology (NFM). 

She also has extensive teaching experience on the human microbiome, bacterial biofilms and quorum sensing, bacterial adhesion, and antimicrobial resistance. As a part of her previous Postdoctoral fellowship, she co-developed and participated as an educator in a Massive Open Online Course (MOOC) on antimicrobial resistance (https://www.futurelearn.com/courses/exploring-the-landscape-of-antibiotic-resistance-in-microbiomes). With the rising threat of emerging antibiotic resistant pathogens, this course aims to raise awareness, educate, and empower individuals to combat this global challenge. By disseminating knowledge on the mechanisms, consequences, and potential solutions of antimicrobial resistance, Gabriela strives to inspire effective actions among a wide audience, including the general public.

Research profile

Gabriela Salvadori’s research interest revolves around bacterial quorum sensing systems, which are cell-to-cell communication processes that regulate bacterial behavior and virulence factors. By unraveling the complexities of bacterial communication, her ultimate goal is to aid in the development of innovative strategies for managing infections and preventing diseases. Her current work involves employing streptococcal quorum sensing systems and genetics in the design of a bio-nanosensor that detects low amounts of different quorum sensing molecules.
