Dr Toby Maher

Dr Toby Maher

Consultant respiratory physician

Background and training

Dr Toby Maher qualified at Southampton Medical School and trained in respiratory medicine at Royal Brompton Hospital, the Transplant Unit at Harefield Hospital and at St Mary’s Hospital, Paddington. During his training he gained an MSc in respiratory medicine from Imperial College London.


In 2005 Dr Maher was awarded a Wellcome Trust Clinical Research Fellowship that enabled him to study the molecular mechanisms involved in the development of idiopathic pulmonary fibrosis. This research was undertaken at the Centre for Respiratory Research, University College London and culminated in the award of a PhD.


Dr Maher is consultant respiratory physician. He also holds the positions of honorary senior lecturer at the National Heart and Lung Institute, Imperial College London, and honorary senior research associate at University College London.  

Areas of expertise


Dr Maher has a subspecialty interest in interstitial lung disease and his areas of expertise include: 

  • idiopathic pulmonary fibrosis (IPF)
  • hypersensitivity pneumonitis
  • sarcoidosis
  • Langerhan's cell histiocytosis
  • Lymphangeiolyomyomatosis

He also manages pulmonary fibrosis and lung disease associated with systemic conditions such as Rheumatoid arthritis, Scleroderma and Wegener’s granulomatosis.

Research interests

Dr Maher's research interests include: 

  • basic and translational research into idiopathic pulmonary fibrosis
  • the use of acoustic lung imaging in diagnosis and disease monitoring in patients with chronic respiratory conditions
  • biomarker discoveries and development of new treatments for interstitial lung disease. 

Dr Maher is also the lead consultant for clinical trials in the Interstitial Lung Disease Unit.


He works closely with scientists at the Centre for Respiratory Research, University College London and has active collaborations with Nottingham University and McMaster University, Canada.


As well as publishing original research, expert reviews and book chapters, Dr Maher acts as an expert reviewer for a number of international respiratory journals and is an associate editor for Respirology.

Dr Toby Maher presented at the American Thoracic Society Meeting in San Francisco in May 2012 and the 17th International Colloquium on Lung and Airway Fibrosis in Modena, Italy in September 2012.


Dr Maher is actively involved in a number of specialist societies, and holds the following positions:
