Tim Warner graduated in pharmacology in 1986 from King’s College London. He then moved to the newly established William Harvey Research Institute to pursue his PhD studies under the supervision of Prof. Sir John Vane (Nobel Laureate, 1982) during which time he was awarded the Premier Prix Annuel de Recherche en Phlébologie. In 1989 he completed his PhD and went to pursue his post-doctoral studies with Ferid Murad (Nobel Laureate 1998) at Northwestern University and Abbott Laboratories, Chicago, USA. He returned to the William Harvey Research Institute in 1992, being awarded a British Heart Foundation lectureship in 1995. He was promoted Reader in Pharmacology in 1999 and awarded a personal chair in Vascular Inflammation in 2000, at which time he was the recipient of the British Pharmacology Society’s Novartis Prize. Prof. Warner has been listed by the Institute for Scientific Information among the top 0.5% of cited pharmacologists. Currently he is also Deputy Dean for Research in the School of Medicine and Dentistry and Deputy Director (Research & Innovation) of QMUL’s Life Science Initiative and previously SMD Deputy Dean for Postgraduate Research. He is a Fellow of the British Pharmacological Society, the American Heart Association and the Society of Biology, he is also a member of the British Society for Cardiovascular Research, International Society for Hypertension Research and the International Society on Thrombosis and Haemostasis. Prof. Warner is currently principal editor of the journal ‘Platelets’.
Undergraduate and Postgraduate teaching
Topics for PhD supervision:
Prof. Warner’s main focus of current research is the roles of different enzyme pathways in the formation of vasoactive mediators such as prostaglandin I2, thromboxane A2 and nitric oxide in blood vessels and blood cells, and so to the control of platelet reactivity within the circulation. Research into prostaglandin formation is supported by programme grant funding from the Wellcome Trust to Prof. Warner in collaboration with Prof. Jane Mitchell at Imperial College. Locally, researchers into platelet reactivity are being pursued in collaboration with clinical colleagues in the Trauma Department, the Ernest Cooke Vascular & Microvascular Unit, and the Cardiac Directorate of the Barts & the London NHS Trust. The British Heart Foundation is currently funding research into the effects of platelet-derived eicosanoids and the pharmacology of anti-platelet drugs. Prof. Warner has also received funding from AstraZeneca and the William Harvey Research Foundation to pursue investigations into interactions between different pathways of platelet activation and their relevance to therapy in particular patient groups.
