Professional background

Dr Kay Roy graduated in medicine in 2000 from the University of Manchester. She was subsequently awarded a PhD in 2008 for research on characterisation of patients with chronic obstructive pulmonary disease (COPD). Her specialist respiratory training was undertaken in the Cambridge deanery.

She was appointed as a consultant in West Hertfordshire before moving in 2020 to lead the asthma service at UCLH. She is also Lead for UCLH's smoking cessation service. Dr Roy supports the complex infection service led by Professor Jeremy Brown and the interstitial lung Disease service led by Professor Jo Porter.

In her current role as an integrated respiratory physician, Dr Roy works closely with the community services involved in COPD care. She is also a member of the respiratory focus group at North Central London CCG and helps to run the specialist lung volume reduction MDT for emphysema.

Dr Roy has been the principal investigator on a number of multicentre clinical trials in COPD and asthma. Her current external duties include roles within the British Thoracic Society, in which she is a member of the quality improvement committee and the pulmonary infection specialist advisory group.

In 2019-2020 she has been a finalist for awards from The British Thoracic Society, The Health Service Journal and The British Medical Journal, for work on community-based projects around COPD exacerbations and point of care testing for infection.
