Omar Usmani MB BS, PhD, FHEA, FRCP, FERS, is Professor of Respiratory Medicine at the National Heart and Lung Institute (NHLI), Imperial College London & Consultant Physician at the Royal Brompton Hospital (RBH) and St Mary's Hospital London. He is Clinical Director of ICRRU (Imperial College Respiratory Research Unit).

He is an International Authority on Aerosol Science and Inhalation Medicine whose research has fundamentally contributed to the understanding of therapeutic aerosol deposition and clinical effectiveness in inhaled drug delivery to the lungs.

In 2015, he was awarded one of the highest accolades in Aerosol Science, the Thomas T Mercer Award from the American Association of Aerosol Research (AAAR) and the International Society of Aerosols in Medicine (ISAM), recognising his International Research Excellence in Pharmaceutical Aerosols and Inhalable Materials.

As Chair of the UK Inhaler Group (UKIG), working with Asthma UK, he oversaw the production of a series of validated videos on inhaler technique and he represents UKIG on the Medicines Optimisation Working Group, part of the Taskforce on Lung Health. He was Chair of the Guidelines Working Party that developed the Inhaler Choice Guideline for UK healthcare professionals in 2017, which was updated in 2020.  

In 2019, he was awarded Fellow of the European Respiratory Society (FERS). In 2020, he was voted by the ERS Assembly 5 members as Head of Assembly 5 (Airway Diseases - Asthma, COPD, Chronic Cough). In 2021, he was elected as President-elect of the International Society of Aerosols in Medicine (ISAM).

Dr Usmani was appointed Co-Deputy Director of Imperial's MBBS Phase programme in 2021, is the Medicine Module Lead (Phase 1c) and Clinical Module Lead of CSI (Clinical Scientific Integration), a flagship Module in Imperial's new MBBS curriculum. He is Co-Director of Imperial's Network of Excellence in Aerosols and Health established in 2021. 

Since 2014, he has organised Outreach Events as part of Imperial's widening participation programme to London secondary and primary school pupils on STEM activities at Imperial College.


Dr Usmani qualified in Medicine at King's College London and has dual Specialist Certification in Respiratory and General Internal Medicine. He underwent his Speciality Training at the London Teaching Hospitals of St Thomas', Guy's and King's College.

During his clinical training he undertook a PhD at Imperial College London, through which his research into Medical Inhalers and Aerosol Science achieved wide Media publicity; BBCNewsOnline, together with his research into the Treatment and Pharmacology of Cough; BBCNewsOnline. He received the 2005 NHLI Best Thesis Prize NHLI PhD Prize for the Best Thesis submitted and an Alavi-Mandell Award from the American Society of Nuclear Medicine.


His Clinical Specialist Interests are Asthma, COPD and Chronic Cough. He is Group Leader of the Clinical Research Group within the Airway Disease Section at NHLI and a Principal Investigator. He is part of the Consultant-led RBH specialist Chronic Cough Service.


His Research Themes are Inhaled Drug Delivery, Small Airways Physiology, Lung Imaging, Respiratory Pharmacology and Tele-monitoring / E-health.

He has pioneered novel and sophisticated techniques of assessing inhaled drug delivery, detecting dysfunction of small airways physiology, and characterising airflow heterogeneity using pulmonary imaging, in order to understand structure-function-treatment relationships within the lungs.

His research expertise has led to invitations to deliver Keynote Lectures at prestigious International scientific meetings. He has written State-of-the Art reviews in his field, and presented his views as a leading expert about the future of inhalation medicine on ERS Vision. He advises on the future of inhalers and respiratory drugs on Advisory Board Panels to the Pharmaceutical Industry. 


In 2012, Dr Usmani was awarded a UK - National Institute for Health Research (NIHR) Career Development Fellowship to investigate the lung deposition behaviour of inhaled bronchodilator aerosols of different particle size within the airways of patients with Chronic Obstructive Pulmonary Disease (COPD). This was the first time this award category was given to Respiratory Science research in the UK.

In 2015, as Lead Clinical PI, he was part of a team awarded a highly prestigious EU HORIZON 2020 grant, myaircoach,  to investigate the role of Tele-monitoring and E-health in asthma self-management, where the proposal was ranked 4th highest of all 256 submissions to the call.

In Jan 2017, he was awarded as Co-PI and Lead Clinician, a highly competitive grant from the UK Newton Fund to tackle the increasing burden of chronic obstructive pulmonary disease (COPD) in China through the development of novel inhalable treatments

In Sep 2017, he was awarded a prestigious 5-year contract by the United States Food and Drug Administration (FDA) as Principal Investigator for a $2.3M project entitled 'Patient's perception of dry powder Inhaler devices' in collaboration with the University of Hertfordshire.

- Chair of the UK Inhaler Group (UKIG) since 2017, having taken over the role from Monica Fletcher OBE

- Vice-Chair of Drug Delivery to the Lungs (DDL) since 2010; Europe's premier scientific conference dedicated to pulmonary and nasal drug delivery

- European Liaison Officer of the International Society of Aerosols in Medicine (ISAM); former Board Member 2013-2017 (maximum two terms) of this International academic organisation dedicated to inhaled drug delivery to the lungs.

- Board Member of the Aerosol Drug Management Improvement Team (ADMIT) since 2014; expert group of European pulmonologists involved in inhalation medicine.

- Associate Editor to the journals Respiration, since 2009 and, to Pulmonary Pharmacology and Therapeutics, since 2016 and, to Breathe, since 2017

- Editorial Board member of Journal of Aerosol Medicine and Pulmonary Drug Delivery, since 2017 and Journal of the COPD Foundation, since its inception in 2014

He was a Steering Committee Member of the Small Airways Working Group of the World Allergy Organization (WAO) between 2012 - 2015; an International organization of Allergology and Clinical Immunology societies from around the world.

In 2016, he was appointed to lead and chair the second updated version of the International ERS/ISAM Taskforce Consensus Statement on "What the pulmonary physician should know about inhaled therapy".


Dr Usmani is a keen educator, teaching and training the next generation of future scientists and doctors. He himself completed CASLAT (Certificate of Advanced Study in Learning and Teaching) awarded by Imperial College London in 2010 and is a Fellow of the Higher Education Academy (FHEA)
