Rafael Galupa is a biologist interested in understanding how cells sense, interpret and regulate differential gene dosage, i.e., the number of copies a gene in the genome. Trained in Molecular Biology and Genetics at the University of Lisbon (BSc. 2007-2010) and in Biomedicine at the Karolinska Institutet (MSc. 2011-2013), Rafael conducted his PhD project at the Institut Curie in Paris under Edith Heard's supervision and obtained his PhD from the Université Paris-Saclay in 2017. This was followed by postdoctoral work at the EMBL in Heidelberg in Justin Crocker's team, a short research stay in Edda Schulz's lab at the MPI-MG in Berlin and a visiting stay in Jérôme Cavaillé's lab at the CBI. In 2023, Rafael joined the CBI as a group leader and the CNRS as a tenured researcher to create and lead the team "Developmental Regulation of Gene Dosage". At the CBI, he is part of the Equality Committee and the PhD programme. Rafael has also been involved since 2006 in professional or voluntary activities in the field of science education with children and young people, including at the Lisbon Zoo. Rafael is a pro bono member of the direction board of Native Scientists and Cartas com Ciência, two NGOs that develop science education programmes with children and youth from minoritised communities underrepresented in academia.
