Investigator Biography

Matthew read natural sciences at Cambridge and stayed to complete a PhD with Stewart Sage (Department of Physiology, Development and Neuroscience) on the regulation of calcium signalling in platelets. He moved to Alastair Poole’s group in Bristol to work on platelet granule secretion and thrombosis. He is on the Editorial Board of the Journal of Thrombosis and Haemostasis, and the Editorial Advisory Panel of the Biochemical Journal. In 2015 he was appointed to a lectureship in the Pharmacology Department. His current research focuses on the triggers of platelet death, how it is controlled, and the role that it plays in thrombosis and thrombocytopenia.
