Ray graduated with a BSc Honours degree in Medical Biochemistry from Royal Holloway, University of London and then successfully completed a PhD CASE studentship in Molecular Biology and Biochemistry at Royal Holloway and Zeneca Agrochemicals. He then began a Postdoctoral Research Fellow position at University College London investigating the molecular biological aspects of beta2-glycoprotein I in antiphospholipid syndrome, and fibrinogen and its association with the thrombophilic markers Factor V Leiden, prothrombin gene mutation G20210A and MTHFR C677T in venous thrombosis, stroke, recurrent miscarriage and pregnancy complications. Since then, Ray’s research has been focused on the genetic and phenotypic links between von Willebrand factor-cleaving protease and thrombotic thrombocytopenic purpura.

Ray became a Senior Lecturer in Biomedical Sciences at the University of Westminster in 2011, where he taught and supervised both undergraduate and postgraduate students, led an integrated part-time BSc Applied Biomedical Science degree, was Admissions Tutor for Biomedical Sciences and was Director of Studies of a PhD student who successfully defended their thesis. Ray joined the academic staff at the 桔子短视频 in September 2017 as a Senior Lecturer in Biomedical Sciences and Course Leader of the BSc Biomedical Science degree. He is also Admissions Tutor for Biomedical Sciences and a member of the Worcester Biomedical Research Group and Health, Life and Environment Research Ethics Committee.

Teaching & Research


These specifically revolve around haematology, and in particular red blood cell haematology and the anaemias and thrombosis and haemostasis, but I also enjoy teaching human anatomy and physiology, fundamentals of disease diagnosis, processes in pathology, biology of disease and certain aspects of biochemistry, cell biology and genetics.

I am currently the module leader and teach on the following modules:

BIOL1004 Human Anatomy and Physiology (Level 4/Year 1)
BIOS2400 Project Development (Level 5/Year 2)
BIOS2401 Professional Aspects of Biomedical Science (Level 5/Year 2)
BIOS3401 Haematology and Transfusion Science (Level 6/Year 3)

I also teach and/or mark on the following modules:

BIOS3002 Independent Study
BIOS3113 The Biochemistry of Cancer


My research interests broadly cover the molecular biological and biochemical aspects of various thrombotic and haemostatic disorders. This has included work on the genotype of the glycoprotein 2GPI and its relationship with antiphospholipid syndrome. It has also included studies on fibrinogen and its association with Factor V Leiden, prothrombin gene mutation G20210A and MTHFR C677T in patients suffering from pulmonary embolism, deep vein thrombosis, cerebral vascular attack, foetal loss and severe obstetric complications. Most recently, I have undertaken research on the molecular biological and functional aspects of von Willebrand factor-cleaving protease (ADAMTS13) and its correlation with thrombotic thrombocytopenic purpura (TTP), a disorder characterised by widespread microvascular platelet-rich thrombi, which result in profound thrombocytopenia and microangiopathic haemolytic anaemia.

I am also a member of the Worcester Biomedical Research Group.
