Professor Stefan Marciniak

Fellow
Subject: Medicine
Proteins must be folded properly to function. If this becomes defective, cells experience stress and respond by clearing away these misfolded proteins for destruction. My lab investigates how the response to this form a cellular stress is important in health and disease. Current projects in our group address a variety of lung diseases including mesothelioma, pulmonary hypertension, and pulmonary fibrosis.

My clinical research focuses on pneumothorax (punctured lungs) and how it can be caused by defective genes or by infections including COVID-19.

Director of Studies in Medicine
Professor of Respiratory Science; Director of the Cambridge MB/PhD Programme; Principal Investigator, Cambridge Institute for Medical Research (CIMR)

I studied medicine at the University of Cambridge as part of its MB/PhD Programme. After medical posts in Cambridge, London and Edinburgh, I undertook post-doctoral training in New York funded by the Wellcome Trust and as an MRC Clinician Scientist Fellow back in Cambridge. I established my own group in CIMR as an MRC Senior Clinical Research Fellow in 2012.  I am now Professor of Respiratory Science at the University of Cambridge and an Honorary Consultant Respiratory Physician at Addenbrooke’s and Royal Papworth Hospitals. My laboratory research focuses on the role of stress signalling in lung disease.  My clinical research focuses on pleural medicine, especially the genetics of pneumothorax. I am Director of the University of Cambridge MB/PhD Programme.
