Short Bio:

Leonilde Moreira is a researcher in Bioengineering and Biosciences and an associate professor at the department of Bioengineering of Instituto Superior Técnico (IST). With a MSc in Biotechnology (1993) and a PhD in Biotechnology (specialization in Microbiology) (1997), Leonilde´s work focuses on the molecular mechanisms of virulence of opportunistic bacteria of the Burkholderia cepacia complex. By combining molecular microbiology, genomics, and evolution, she pursues to uncover the genetic and phenotypic adaptation of these bacteria during long-term chronic respiratory infections of cystic fibrosis patients. To promote science across different audiences, she co-organized workshops and practical courses for biology teachers and pupils.

Research Focus:

Comparative genomics to understand long-term evolution of Burkholderia multivorans isolates from cystic fibrosis patients and identification of bacterial genetic determinants implicated in multicellular aggregates formation.
