working on PhD entitle “Assess sediment trophic status and functional responses of benthic communities in Sado estuary (Portugal): Integrating metagenomic and stable isotopes approaches.”, it's focused on how environmental changes (natural and anthropogenic) can shape the benthic communities and affect sediment trophic status evaluating the multiple and complex interactions between organisms and the energy transfer analyzing stable isotopes and caracterize microbiome using 16S metagenomic
