Full Professor with Habilitation in Biomedical Sciences (Speciality Microbiology) in the Unit of Medical Microbiology of the Instituto de Higiene e Medicina Tropical and Global Health and Tropical Medicine from Universidade NOVA de Lisboa.

Bachelor in Sciences (Biology) with Major in Microbiology, a Master in Sciences in Biotechnology (Chemical Engineering) and a PhD degree in Biology (Microbial Genetics) from the Universidade de Lisboa.

In 2012 obtained the Habilitation in Biomedical Sciences (Speciality Microbiology) by the Instituto de Higiene e Medicina Tropical da Universidade Nova de Lisboa

Currently, researcher and teacher in Medical Microbiology, President of the Pedagogical Council of the IHMT/UNL and invited professor at the Faculdade de Medicina do Rio de Janeiro (Brasil).

His main areas of interest are in support of the mission and institutional strategy of teaching and capacity building for the Community of Portuguese Language Countries (CPLP) in Biomedical Sciences, International Health and Tropical Medicine. Scientific activity devoted to the early diagnosis of active or latent tuberculosis (TB) infections as well as the development of new diagnostic and therapeutic approaches to deal with MDRTB and with other drug resistant bacterial infections. Research mainly focused on tuberculosis and antibiotic resistant infections in support for alternative therapies of incurable diseases such as multidrug resistant tuberculosis and methicillin-vancomycin resistant staphylococcal infections using non-antibiotic adjuvants of the chemotherapy, as well as the early diagnosis of tuberculosis in low-resource countries by new nanotechnology based technologies.  Special interest in the study of the contribution of transporters and physiology to resistance, adding to the well-known and studied resistance by genetic mutations and the development of techniques to assess efflux by bacteria in a real time manner. Appling these techniques to different groups of bacteria he has been able to demonstrate the importance of the efflux activity in the overall resistance to different groups of antibiotics, namely in Mycobacteria and Staphylococcus aureus where, for many years the scientific community refused to accept their role in resistance, as well as contributed to the assessment of chemical inhibitors of efflux as putative adjuvants of antimicrobial therapy. Interested also in molecular biology of mycobacteria and immunology of TB. As Director of the TB Laboratory of the IHMT (since 2001) has contributed to the resolution of the pulmonary TB problem of Lisbon by the generation of complete reports within a period of 15 to 20 days for 10 Hospitals of the TB Task Force of Lisbon.

He has led eight research projects in those areas (aprox. 1,5M€), supervised and/or co-supervised several postgraduate degrees (5 pos-docs, 10 PhD, 24 MSc students) , and acted as consultant for the Portuguese National Directorate of Health, CPLP board and Health Ministries, Foundation of Sciences and Technologies of Portugal and ECDC. Founding member and Treasurer (until 2017), currently management committee member of the Study Group for Mycobacterial Infections (ESGMYC) of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) ( https://www.escmid.org/index.php?id=897 ). Elected Vice-chair of the Gordon Research Conference - Multi-Drug Efflux Systems - 2017-2019 - https://www.grc.org/programs.aspx?id=13929. Member of the evaluation panel of Individual Doctoral and Post-doctoral Grant proposals - area Biomedical Sciences and Basic Medicine -2013-2015 -Fundação para a Ciência e a Tecnologia – Ministério da Educação e Ciência de Portugal. Expert Evaluator for the Medical Research Council of UK calls (area Tuberculosis). Member of the Review and Advisory Panel of the ‘Wellcome Trust Awards”, UK. Ad-hoc reviewer for the expert panel of the The Research Foundation – Flanders (FWO), Belgium, Haut Conseil de l'évaluation de la recherche et de l'enseignement supérieur (HCERES), France and National Agency for Scientific Evaluation (ANEP), Spain. Member of the evaluation panels for the QREN R&D investment proposals of the Ministério da Economia de Portugal. Regular ad-hoc reviewer of several international scientific journal (Lancet, Nature, JAC, AAC, PlosOne, IJAA, Tuberculosis, BMC Microbiology, etc) . 2010 - present.
