Research Topics:
My previous and current scientific activities have been mainly developed in the Microbiology area of research. Since July 2009 I assumed a Ciencia2008 position at Faculty of Veterinarian Medicine and I'm now trying to obtain funds to establish my own Microbiology research lab, working with bacteria found in food and assessing for their pathogenicity potential, by comparison with human and veterinarian clinical isolates. Over the years the establishment of several collaborations with distinct institutions enriched my scientific and personal accomplishments that I intend to mantain and expand. The Microbiology lab at Lisbon Faculty of Sciences, where I worked for several years, has always acted as an ‘open lab’, following that approach we have always received students (graduated and under-graduated) or researchers that needed our expertises. The theoretical and practical courses in which I participated since 1999 are a clear example of our will to share and acquire knowledge. So, over the years I developed skills on diverse areas, including standard Microbiology methodologies (e.g., microscopy, culture and conservation of microorganisms, phenotypic and biochemical characterization), molecular tools (e.g., DNA, RNA and protein isolation; RFLPs, cloning, PCR, RT-PCR) and data analysis (handling of specific software e.g., NTSYS, KODAK 1D, GelCompar and Bionumerics). Being an academic as well as research laboratory the Microbiology lab always required special attention concerning its management. This laborious and time-consuming work has been performed in collaboration between the lab manager and the post-doctoral researchers. My research interests have always been directed towards Microbiology in diverse fields, including Environmental, Food and Clinical Microbiology. I began working in the identification of microorganisms but over the last years my research expanded to the assessment of pathogenic potential, screening for virulence determinants and evaluation of the environmental cues that trigger the expression of such traits. Human bacterial pathogens and the mechanisms involved in their pathogenicity are still far from fully unraveled, turning the research in this area appealing and stimulating. Nowadays I intend to mantain the line of work already established and also develop research activities towards the screening for Mobile Genetic Elements (MGEs) responsible for the spread of virulence determinants in order to further unravel the mechanisms responsible for the conversion of commensal bacteria in opportunistic pathogens responsable for life-threatening infections in humans and animals.


Organisms studied:
  • Enterococcus spp


Special methods / technologies:
PCR, RT-PCR Proteomics 1 DE and 2DE PAGE Transcriptomics, RAP-PCR


Suggestions for potential research cooperations:
Since 1999 the research group I integrated at Lisbon Faculty of Sciences until June 2009 (and with which I mantain strong collaborations), known as ‘Bugworkers’ decided to prepare courses directed to graduated researches or members of the academia that felt the need to learn or enhance their knowledge on microbial and molecular methodologies. I participated since the beginning contributing to the elaboration of protocols, selection of the supplied material and preparation of all the biological and non-biological materials needed.
As a teaching monitor I participated in all the lab sessions and several of the Lecture/Laboratory classes. In conclusion, as a teaching monitor I participated in 10 National and 1 International Course between 1999 and 2007.
