I completed BSc and PhD degrees in Immunology at Kings College London, before undertaking Postdoctoral fellowships at Guys Hospital London and Harvard Medical School, Boston. I moved to Millennium Pharmaceuticals in Cambridge USA as a scientist in the Inflammation Division, where I was involved in the cloning and in vivo characterisation of novel genes involved in Th2 responses. I moved back to the UK to start a Wellcome Senior Fellowship in Basic Biomedical Sciences in the Leukocyte Biology Section at Imperial College. I renewed my Fellowship in 2004, 2009 and 2015. I was awarded a Professorial Chair in Respiratory Immunology in 2006 and took over as Head of Section in 2010, and as Head of Division of Respiratory Sciences in 2015. I was the Institute’s Lead for Women (2009-2015) and led our application for Athena Swan status, and we achieved Silver Swan Awards in 2010 and 2014. I am the academic advisor to the Vice Provost (Research) on Early Career Researchers. I was Deputy Editor of Thorax (2010-2015), am an associate editor of Mucosal Immunology and an advisory editor for Journal of Experimental Medicine. My lab investigates epithelial-immune interactions underlying development and resolution of allergic airway inflammation. We are predominantly focused on how the genetic background of an individual and the external environment influences these interactions, particularly with respect to infection history and development of allergic immune responses in early life.
