Mariana received her B.Pharm from the Federal University of Minas Gerais (Brazil) where she completed her PhD in Pharmaceutical sciences in December 2014. Her undergraduate research first focused on identification of mutations that affect haemostasis and later on the analysis of synthetic peptides aiming towards improvement in clinical diagnosis of visceral leishmaniasis and the development of canine leishmaniasis vaccines. In 2011 she joined the Centre of Metabolomics and Bioanalysis (CEMBIO), San Pablo, Spain) as part of her sandwich doctorate to investigate early biomarkers for canine leishmaniasis through metabolomic approaches. In 2015, she joined the Metabolomics STP at the Francis Crick Institute and is working on the development and application of LC-MS methods for metabolomics and lipidomics research. Her current project, in collaboration with Luiz Carvalho, aims to unveil protein function in M. tuberculosis through metabolomics and lipidomics approaches. She is also investigating the involvement of M. tuberculosis lipids in pathogenicity and virulence and how the TB lipidome could be used to identify new therapeutic targets.
