Chair of Pneumology
Innovative research and clinical excellence in respiratory medicine
The Chair of Pneumology at Witten/Herdecke University is based at the Pulmonary Clinic of Cologne Merheim Medical Centre, part of Kliniken der Stadt Köln gGmbH. The Chair is held by the Head of the Department of Respiratory Medicine, Professor Dr Wolfram Windisch.
As an organ centre, the Pulmonary Clinic is an interdisciplinary clinic comprising the departments of Pulmonology and Thoracic Surgery. It offers comprehensive diagnosis and treatment of all diseases of the chest, with the exception of the heart.
The clinic comprises the following centres and areas of specialisation:
- Non-invasive ventilation and weaning
- Quality of life and health care research in respiratory medicine
- ARDS and ECMO Centre, respiratory intensive care
- Lung Cancer Centre
- Severe chronic obstructive pulmonary diseases
- Rare and interstitial lung diseases
- COVID-19 and Long COVID
- Tuberculosis and non-tuberculous mycobacterial infections
- Alpha-1 Antitrypsin Centre
- Cystic fibrosis and non-CF bronchiectasis
- Diaphragmatic dysfunction.

Research
The Chair of Pneumology, which specialises in respiratory failure and ventilatory medicine, is a centre for innovative research and clinical excellence. The Chair’s research activities focus on the development of new therapeutic approaches and technologies for the treatment of patients with acute and chronic respiratory failure.
Our main area of research is acute and chronic respiratory failure. In this context, members of the department play a leading role in the development of national and international guidelines (see staff profiles). Our research activities cover the entire field of respiratory medicine. Through the affiliated professorship in ECMO, the research group investigates innovative treatment options in intensive care medicine. The research group specialising in chronic respiratory failure, on the other hand, addresses all aspects of chronic respiratory failure, from diagnosis through to treatment. In addition to investigating the pathophysiological basis of these conditions, the focus is particularly on non-invasive respiratory medicine and health care research. To this end, the Chair of Pneumology collaborates both with various specialist pneumology clinics and with other departments such as neurology and infectious diseases.
Interstitial lung diseases are also a major focus at the Chair of Pneumology. An interdisciplinary team comprising pulmonologists and rheumatologists from affiliated hospitals deals with these conditions, some of which are extremely rare.
The Chair’s research activities are of great importance, as they not only improve our understanding of respiratory failure but also help to enhance the quality of life of affected patients and optimise treatment methods and care. Interdisciplinary collaboration with other departments and international research institutions plays a crucial role in this regard.

Teaching
The staff and contract lecturers at the Pulmonary Clinic are actively involved in the process of further developing teaching at Witten/Herdecke University. Teaching therefore plays a particularly important role at the Pulmonary Clinic. Teaching for students at Witten/Herdecke University as part of the model medical degree programme takes place during the ‘Internal Medicine’ practical block, in collaboration with colleagues from Medical Clinic I.
In addition, the Pulmonary Clinic offers training opportunities for students in the form of clinical clerkships of all kinds and during the practical year (PJ).

Partnerships
The Pulmonary Clinic in Cologne-Merheim comprises the specialist departments of Thoracic Surgery, headed by Prof. Dr Stéphane Collaud, and Pulmonology, headed by Prof. Dr Wolfram Windisch. In addition, an oncology outpatient clinic is affiliated with the clinic, which, in combination with the various specialist outpatient clinics, enables holistic, interdisciplinary patient care and stimulates interdisciplinary research. We also welcome diverse and often interdisciplinary collaborations. Of particular note here are:
