Andrew Holmes is a Lecturer in Cardiac and Respiratory Physiology in the Institute of Clinical Sciences.

His research interests are in the field of cardiovascular and respiratory physiology and pathology, with an emphasis on identifying novel mechanisms underlying hypertension and cardiac arrhythmia.

Dr Holmes has a key research focus on evaluating how cardiorespiratory reflex dysfunction caused by hyperactive carotid body chemoreceptors promotes hypertension and cardiac autonomic dysfunction. He aims to develop new or repurposed therapies that directly target the carotid body to reduce hypertension and arrhythmia in associated diseases such as obstructive sleep apnoea and COPD. This work is currently supported by the Wellcome Trust.

In addition, he has a specific interest in understanding how acute and chronic hypoxia disrupt the electrical integrity of atrial tissue leading to heart rhythm disturbances. This work is currently supported by grants from BHF.  

Dr Holmes is an enthusiastic teacher and contributes to the delivery of both undergraduate and postgraduate courses. He is joint module lead on the Biomedical Science BSc Year 3 module- Hypoxia in Health and Disease.
