I am a Consultant Respiratory Physician at the Royal Brompton and Harefield NHS Foundation Trust and Horonary Clinical Senior Lecturer at Imperial College London.

Following completion of my medical training at Imperial College London alongside an intercalated BSc, I trained as a respiratory doctor within North West London and spent time working within the lung transplant unit at Harefield Hospital and the Host Defence Unit at the Royal Brompton hospital. It was during this time that I encountered numerous individuals with fungal lung infection and developed my academic interest to try and better understand host susceptibility to fungal infection and develop translational research strategies to improve outcome.

This interest led to a MRC clinical PhD research fellowship in 2012-2015 in the Armstrong-James laboratory at Imperial College London analysing the effects of calcineurin inhibition on the human macrophage response to Aspergillus fumigatus using a combination of high-resolution time-lapse confocal microscopy alongside an 'omics' based approach. This work was published in the American Journal of Critical Care Medicine and presented at numerous national and international presentations.

Following completion of my PhD and clinical training, I took up a Consultant position at the Royal Brompton and Harefield NHS Foundation Trust in October 2016, working in the adult Cystic Fibrosis and Host Defence departments. I have continued and expanded my academic interests and research during this time, receiving numerous research awards and funding.
