Joana Cristina Pacheco Barbosa

PhD in Biology – Specialization Molecular Biology and Genetics – at Universidade de Aveiro in collaboration with the Technical University of Berlin and Instituto de Medicina Molecular, Lisboa. Main research areas include: natural products of bacterial origin, particularly with antibiotic bioactivity, and their characterization in terms of structure, activity, mode of action and cytotoxicity; genetic manipulation and heterologous expression of bioactive compounds of interest; antibiotic resistance spreading surveillance; probiotic strains and their biomolecular and genetic characterization; food biotechnology. Currently, PhD researcher from CAPEOSBAC project – “Tailored microenCAPsulation technology for Extreme Oxygen-Sensitive BACteria with beneficial effects in the gut microbiota: Production, stability and functionality enhancements in various carriers”, focused on: characterization of the interaction between probiotic strains and eukaryotic cells; characterization of probiotic strains delivery systems, in terms of efficacy and safety; biomolecular assessment of probiotic strains fitness when subject to different stressors; genome mining approaches for genetic characterization of probiotic strains.
