translational control



Juana Díez studied biology and obtained her PhD from the University Autónoma of Madrid, Spain (PhD prize). For her post-doc she moved to the Institute of Virology (Madison, USA) where she carried the first genome-wide identification of host factors restricting viral replication under the supervision of Dr. Paul Ahlquist. In 2001 she obtained a professorship  at the Department of Experimental and Health Sciences at the University Pompeu Fabra (Barcelona, Spain) where since then she leads the Molecular Virology group and coordinates the Microbiology teaching Unit. She is a full professor from 2017. Currently her lab is financed by Spanish and European grants. She received in 2016 the ICREA Academia award for excellence in research and in 2019 the Technology Transfer award.



The main focus of her group is to decipher key molecular interactions of emerging viruses with their host cells and to use this knowledge to develop broad-spectrum antivirals. Her group combines transcriptome-wide translational analyses and cellular and molecular biology approaches to elucidate the complex and dynamic interactions that these viruses establish in human and mosquito cells to expand.
