Dr Beatriz Guillen Guio

I am a Sir Henry Wellcome Trust postdoctoral fellow working on the study of pulmonary fibrosis, acute respiratory distress syndrome (ARDS), and COVID-19 genetics.

I completed my BSc in Biotechnology at the University of Salamanca (Spain), my MSc in Biochemistry, Molecular Biology and Biomedicine at Complutense University of Madrid, and my PhD in Health Sciences at the University Hospital Nuestra Senora de Candelaria (Spain). I joined the University of Leicester in 2021.

Genetic and environmental factors influence COVID-19 susceptibility and outcomes, including the development of acute respiratory distress syndrome (ARDS), characterised by pulmonary infiltrates and severe hypoxaemia, and short- and long-term pulmonary fibrosis (i.e., lung scarring). These lung pathologies have a high mortality and there are no specific treatment options or effective prognostic methods for patients.

I currently hold a Sir Henry Wellcome Postdoctoral Fellowship to further study the genetics of pulmonary fibrosis, ARDS and COVID-19, including assessing potential genetic overlap between these three phenotypes. I am also involved in large initiatives including The Post-hospitalisation COVID-19 study (PHOSP-COVID) and the Spanish COalition to Unlock Research on host GEnetics on COVID-19 (SCOURGE).
