Research Interests

Pharmaco-toxicology motivates Margarida Silva and her students to investigate drug-induced actions and reactions in relevant diseases for the improvement of therapeutic approaches. Her projects focus on elucidating the effects of small acid drugs on mitochondrial metabolism, cell bioenergetics and on the modulation of protein acetylation. Metabolite-targeted mass spectrometry (GC-MS, LC-MS/MS) is used for analyses of biomarkers in biological samples and for the characterization of specific targets at the biochemical and molecular levels.
