Ioannis has worked in the areas of pulmonary rehabilitation and clinical exercise physiology for over 30 years. For 3 years he was the Chair of the Rehabilitation and Chronic Care group of the European Respiratory Society (ERS) and has served the ERS as the Head of the largest Assembly (Respiratory, Clinical Care & Physiology). Ioannis represents the ERS on the World Rehabilitation Alliance hosted by the World Health Organisation (WHO). He has contributed to several joint ERS and American Thoracic Society (ATS) Statements on pulmonary rehabilitation, skeletal muscle dysfunction, cardiopulmonary exercise testing, respiratory muscle function assessment and physical inactivity in patients with COPD. He has co-chaired the ATS/ERS joint policy statement for enhancing the implementation, use and delivery of pulmonary rehabilitation globally.  He was a member of the Development Group for COPD for the WHO Rehabilitation Programme. He is currently a member of the National Institute for Health and Care Excellence (NICE) expert advisory panel for managing the long-term effects of COVID-19. His research focuses on the benefits of therapeutic exercise training in people with respiratory disease, long COVID and multimorbidity.  Ioannis is an Honorary Research Fellow at Newcastle Hospitals NHS Foundation Trust.   

Ioannis has worked in the areas of pulmonary rehabilitation and clinical exercise physiology for over 30 years. He is an opinion leader in pulmonary rehabilitation. This is attested by co-authorship on several Joint European Respiratory Society ERS (ERS) and American Thoracic Society (ATS) Statements on pulmonary rehabilitation, skeletal muscle dysfunction in COPD, standardisation of cardiopulmonary exercise testing in chronic lung diseases, respiratory muscle testing and physical inactivity in patients with COPD. He has co-chaired an ATS/ERS joint policy statement on enhancing the implementation, use and delivery of pulmonary rehabilitation globally. In recognition of excellence in scientific and educational contributions to Respiratory Medicine over many years, the ERS elected Ioannis a Fellow of the Society in 2018.  Under the auspices of the British Thoracic Society (BTS) Ioannis recently contributed to the clinical statement and quality standards on pulmonary rehabilitation.  

For 3 years Ioannis was the Chair of the Rehabilitation and Chronic Care group of the European Respiratory Society (ERS) and he is currently serving the ERS as the Head of the largest Assembly (Respiratory, Clinical Care & Physiology) counting >12,000 members. Ioannis represents the ERS on the World Rehabilitation Alliance hosted by the World Health Organisation (WHO). He was a member of the Development Group for COPD for the WHO Rehabilitation Programme. He is currently a member of the National Institute for Health and Care Excellence (NICE) expert advisory panel for managing the long-term effects of COVID-19.  Ioannis served the British Thoracic Society as a member of the Pulmonary Rehabilitation Advisory Group for 3 years.  

Ioannis has a sustained record of academic achievement at the highest international level. He is an Associate Editor for two journals (the European Respiratory Journal Open Research and the Chronic Respiratory Disease journal); He is an editorial board member for two journals: the Journal of Applied Physiology and Respiratory Physiology and Neurobiology journal; He has over 200 research outputs, exceeding 30,000 citations; Ioannis possesses 143 citations across 87 policy documents; 47 policy documents which cite his work have been cited a further 633 times in 400 other policy documents. He maintains a sustained record of keynote speaker invitations by several international respiratory medicine societies.

Ioannis demonstrates a lead role in high-impact interdisciplinary collaborations with a wide range of academic, industrial or government partners. Ioannis is member of the Mobilise-D consortium funded by the Innovative Medicines Initiative (a public-private partnership between the European Union and the European Federation of Pharmaceutical Industries and Associations) that lead to the development of digital biomarkers in mobility for several single long-term conditions. He is a member of the Post-Hospitalisation COVID-19 consortium (PHOSP-COVID) funded by the MRC/NIHR – a consortium of leading researchers and clinicians from across the UK working together to understand and improve long-term health outcomes for patients who have been in hospital with confirmed COVID-19. He has been a member of the research team for the multicentre NIHR-funded PERFORM trial (Personalised Exercise Rehabilitation FOR people with Multiple long-term conditions). He is currently the chief investigator of an MRC Gap Fund investigating digital mobility outcomes in people with multiple long-term conditions.

His research focuses on the benefits of therapeutic exercise in people with respiratory disease, long COVID and multimorbidity.  Ioannis is an Honorary Research Fellow at Newcastle Hospitals NHS Foundation Trust and maintains collaborations with several clinicians.
