In 1990, she held the position of senior researcher at
The Rockefeller University in
New York, and starting from 1999, she also taught at the António Xavier Institute of Chemical and Biological Technology of the
New University of Lisbon, where she retired in 2011.[5][6]
Scientific work
Her research focused on studying the resistance of
pathogenic bacteria to
antibiotics, aiming to discover how bacteria acquire it, the genetic basis behind it, and how it develops in a population of bacteria.[7]
Thus, she studied from the perspective of microbial genetics, biochemistry, and molecular biology of
phagosomes and
Gram-positive bacteria, analyzing their mechanisms of
antibiotic resistance and the diffusion of clones and resistant genes.[5]
She studies the leading cause of hospital infections, the Staphylococcus aureus bacteria, particularly methicillin-resistant strains, which can cause severe infections such as
septic shock,
septicemia,
endocarditis, among others.[8][9]
In 2017, the team led by her and Maria Miragaia at ITQB decoded the gene in bacteria responsible for antibiotic resistance.[10]
Awards and recognition
She received the Professor Nicolau van Uden Award from the Portuguese Society of Microbiology for her contributions to this area of knowledge.[8][11][12][13]
In 2016, she was one of the Portuguese scientists honored by Ciência Viva in the first edition of the book and exhibition Mulheres na Ciência (Women in Science).[7]
She became a retired professor at the ceremony held in December 2017 at the António Xavier Institute of Chemical and Biological Technology.[5]
Hermínia de Lencastre was awarded the Medal of Scientific Merit by the Portuguese Ministry of Science, Technology and Higher Education in 2018.[14]
