Isabel Silveira
Group leader
Isabel Silveira graduated in Pharmaceutical Sciences from the University of Porto, Portugal, in 1990. She then pursued her studies in Molecular and Cellular Biology at the University Paris V in France. In 1997 she obtained her PhD degree in human genetics specializing in disease gene mapping.Her current work focuses on finding genes implicated in neurodegenerative diseases towards development of genetic diagnosis and treatment for these pathologies.
