Andrew Ritchie is a Clinical Research Fellow at the National Heart and Lung Institute and Honorary SpR at the Royal Brompton and Harefield NHS trust.

Andrew qualified from the University of Sheffield medical school in 2009. He intercalated with a BMedSci. in medical research. His work, characterising the surface proteome in Oviductal Epithelial Cells during the Reproductive Cycle, was awarded First Class Honours. In 2013, he was appointed to the post of NIHR Academic clinical fellow in Respiratory Medicine at Imperial College.

As a respiratory physician, his research interest focuses on the interplay of host-immunity, respiratory viruses and bacteria in the context of chronic lung diseases. He is currently undertaking a PhD. examining and investigating the nature of susceptibility to respiratory infections in Early COPD supervised by Professor Wedzicha. This has involved helping the group with their wider aim, to recruit a novel cohort of individuals at risk of developing COPD (>10 pyh tobacco, aged 30-45).

During his time at Imperial he has also spent 9 months in Professor Seb Johnston's group researching the pro-inflammatory effects of beta-2-agonists in asthma.

In 2016 Andrew began the role of Editorial Coordinator at the American Thoracic society for the AJRCCM, their flagship journal. This requires close work with the journal's senior editors to commission editorials and ensure timely peer review of manuscripts. His position at the journal has allowed him carry out a research project on the subject of peer review anonymity, and those findings were presented at the 2018 ATS meeting and have been subsequently published.
