Dr Christina Warboys is a Lecturer in Basic Sciences and a British Heart Foundation Intermediate Research Fellow. Her background is in Cardiovascular Biology with a particular interest in endothelial cell mechanobiology.

Dr Warboys joined the Royal Veterinary College in 2019 as Lecturer in Basic Sciences. Dr Warboys obtained a first class honours degree in Medical Biochemistry from the University of Leicester before completing a PhD in Vascular Physiology in the Cardiovascular Division at King’s College London. In 2006 she began her postdoctoral research career in the Department of Bioengineering at Imperial College London followed by positions in the National Heart and Lung Institute at Imperial College and Cardiovascular Division at King’s College London. In 2016 Dr Warboys was awarded a British Heart Foundation Intermediate (Basic Science) Research Fellowship to investigate the role of β-catenin in the regulation of mechanical signalling in the endothelium.

During her postdoctoral studies Dr Warboys supervised several MRes, MSc and PhD students and has been actively involved in the day-to-day running of research facilities and numerous departmental and early career researcher committees. She also has extensive teaching experience and before beginning her Research Fellowship worked as Teaching Fellow in Physiology within the Department of Bioscience Education at King’s College London.

Dr Warboys is an elected committee member of the British Society for Cardiovascular Research.

Dr Warboys is interested in the initiation and development of cardiovascular disease, in particular how mechanical forces (such as shear stress) control the spatial localisation of atherosclerosis, that specifically occurs in regions of disturbed shear stress. With the support of her BHF Fellowship, she is currently investigating the mechanical regulation of the Wnt/β-catenin signalling pathway in endothelial cells utilising an orbital shaker model to expose cells to disturbed (atherogenic) or undisturbed (atheroprotective) shear stress. Her particular focus is on how β-catenin mechanosignalling regulates inflammation and permeability.

She also has an on-going collaboration with Professor Albert Ferro at King’s College London to investigate shear-regulated apoptotic signalling.
