PUJADES CORBI, CRISTINA
Personal profile in our Scientific Output Portal (PPC)
I am Full Professor at the Universitat Pompeu Fabra. After getting my PhD in Biology from the Universitat de Barcelona in 1991, I went for a postdoctoral stay to the Dana Farber Cancer Institute at Harvard Medical School (Boston) where I worked in cell adhesion receptors. Looking for a more holistic view of science, in late 1995 I moved to the École Normale Supérieure in Paris to study the embryonic development of the Central Nervous System (CNS). I spent several years in Paris, first as a postdoctoral fellow in the ENS (1995-99), and then with an independent position at the Université Pierre et Marie Curie (1999-2010). In 2002, I joined the Department of Experimental and Health Sciences at the Universitat Pompeu Fabra, where I have been Academic Secretary (2007-10) and Vice-Chair (2010-13). I got the ICREA Academia award by the Generalitat de Catalunya (2016-2020).
We focus our studies on the embryonic development of the hindbrain, as a model to understand how cellular compartments operate during brain development, and how the neurogenic capacity is allocated. Our interest is to unveil when and how brain progenitors commit to a given fate and how they behave once committed. Therefore we tackle this studying how and when cell fate is established and how the different cell lineages are generated within the brain. We combine high-resolution imaging with genetics, using the zebrafish embryo as a model system (www.pujadeslab.upf.edu; @CristinaPujades).

Public Dissemination of Science
The UPF strongly believes that public universities have an obligation to inform the public of their work, and to establish an open dialogue with society with regards to findings that may have a strong impact on health and society. Members of Pujades lab are highly committed to the Public Dissemination of Science and contribute to the dissemination of their findings to a larger non-specialized public.
