​​​​
​Prof Coenie Koegelenbe​​​rg, the Head of Division, is nationally and internationally recognized for his work in interventional pulmonology, lung cancer and pleural diseases and has advanced many local and international guidelines through his ground-breaking work. He heads the Interventional Pulmonology Service which is the premier service on the continent.  He is a past president of the South African Thoracic Society (SATS), and currently serves on the society's executive council.

​Prof Brian Allwood has been instrumental in establishing the Pulmonary Hypertension & CTEPH Service after completing a Fellowship in Pulmonary Hypertension at Massachusetts's General Hospital/Harvard, USA. He heads the Interstitial Lung Disease Service and established the first Post-Tuberculosis Lung Disease Clinic in the world. He has achieved international acclaim for his body of work in this field which continues to evolve. Prof Allwood has served on the SATS council for several years.

Associate Professor Jane A Shaw is a clinician-scientist affiliated with the Division of Pulmonology and the Division of Immunology in the Department of Biomedical Sciences, where she pursues her research into the pathobiology of pleural tuberculosis and the host immune response to Mycobacterium tuberculosis. In addition to her research in pleural and pulmonary TB and their sequelae, she is a skilled proceduralist with a particular passion for teaching thoracic ultrasound to improve patient safety and diagnostic yield from transthoracic procedures.

​Dr Usha Lalla is uniquely poised as a dual specialist in Critical Care and Pulmonology. The management and training within the intensive care unit occur under her 10 years of experience and expertise as an intensivist. She is also furthering research in TB therapeutics within critically unwell patients, which greatly expands current understanding and will guide clinical management. Dr Lalla was recently elected to serve on the SATS council.

​Dr Nevadna Singh has a keen interest in the interstitial lung diseases, as well as obstructive airways diseases. She is also invested in expanding the use and utility of cardiopulmonary exercise testing to improve the understanding and management of patients with complex cardiopulmonary pathology. She heads the Division's academic programme and is central to the successful training of both their physicians and pulmonologists

​Emeritus Prof Elvis Irusen has previously served as head of the division, president of the South African Thoracic Society, and the SA representative on the European Respiratory Society and GOLD. He has a particular interest in molecular and clinical aspects of asthma and COPD.

Dr Saadiq Moolla is a clinician researcher with a broad range of interests in pulmonology. His current research focus extends to post-tuberculous lung disease. He has a particular interest in technology where his work aims to bridge the gap between clinical practice and innovative digital tools to improve patient care and health systems.

​Dr Mohamed Faried Abdullah is one of our externally funded Pulmonology fellows. He earned his Fellowship of the College of Physicians (FCP SA) through the University of Cape Town and is currently completing an MPhil in Pulmonology at Stellenbosch University, supported by a Melomed Private Hospitals Group scholarship. During the COVID-19 pandemic, he served on the front-line team at Brackengate Intermediate Care Hospital, gaining extensive experience managing severe respiratory failure and coordinating multidisciplinary care. 

​Dr Gordon Audley is a specialist physician who  completed his undergraduate and physician training at Groote Schuur Hospital. He has now joined the Tygerberg Pulmonology team as a fellow. He has a keen interest in Critical Care and Interventional Pulmonology.

​Dr Nicola Wills joined as a fellow in May 2025 after completing her physician training at Groote Schuur Hospital in January 2025. With an initial interest in infectious diseases, and conducting research on PCP in Botswana following completion of a Masters in Tropical Medicine at the London School of Hygiene and Tropical Medicine, her research journey has pivoted towards the rich interface of infectious diseases and pulmonology. As a fellow, her goals include extending a clinical focus and contributing to translational research in infectious, interstitial and autoimmune disease, critical care as well as cardiopulmonary exercise testing.
