Mary Morrell is Professor of Sleep and Respiratory Physiology at the National Heart and Lung Institute, Imperial College London. She received her PhD in Physiology from London University, having previously trained and practiced as a Nurse at St Mary's Hospital, Paddington. As PhD student in the Department of Respiratory Medicine at Charing Cross Hospital she developed an interest in sleep and the control of breathing, which had shaped her research career.
Mary is the Interim Head of the newly formed Cumbria School of Medicine and Director of Phase One (Years 1-3) of Imperial College School of Medicine MBBS programme.
Research: Mary completed her Post-doc training at the University of Wisconsin-Madison, funded by a Wellcome Trust Prize International Travelling Research Fellowship. Upon her return to the UK, she set-up the Academic Unit of Sleep and Breathing with clinical colleagues at the Royal Brompton Hospital. The group aimed to investigate the causes and consequences of sleep disordered breathing. Specifically, to translate research findings into improvements in patient care. This led her to establish a UK respiratory sleep research network. The trials carried out by this team have been incorporated into national healthcare guidelines (NICE: National Institute for Health and Care Excellence, UK) and increased treatment options for patients with sleep apnoea.
Leadership: Mary has served on the Board of Directors of the American Thoracic Society as Chair of the Respiratory Neurobiology and Sleep Assembly, and on the Executive Committee of the Physiological Society as a Trustee and Chair of Policy Committee. She is a former President of the British Sleep Society.
Education: ‘Education is freedom’ and Mary is an enthueastic life long learner. As Director of Phase One she is responsible for the first 3 years of the MBBS programme, managing a team of educators and over 1,000 students. In August 2023, she was appointed the Interim Head of the newly formed Cumbria School of Medicine.
Imperial College School of Medicine has recently completed a major curriculum review, rolling out a new MBBS programme in 2019-20. Mary led a team of over 60 people, to develop the new Phase One curriculum with a focus on clinical skills, underpinned by the scientific understanding of medicine; incorporating the use of technology and preparing our students for the introduction of the new Medical Licensing Assessment and the challenges of working in the NHS.
Mary has also developed other educational programmes including an MSc Cardiovascular and Respiratory Healthcare, which she led for 5 years. An intercalated BSc in Remote Medicine - in collaboration with Dr Andrew Derby-Smith, and a Research Development Course, which is now managed by the Clinical Academic Training Office. She has also supervised 25 PhD/MD research fellows from a range of clinical and scientific backgrounds (2 students currently registered)
In 2014, Mary was awarded the President's Medal for Excellence in Teaching in recognition for her leadership in the development of the Imperial College Success Guide for Undergraduate students.
When not in the lab or teaching, Mary has also carried out Sleep Research Projects at high altitude and has held a Wellcome Trust Science Arts Grant.
