Roy's interest were always in biology although he originally read chemistry as a sound knowledge of chemistry is a good grounding for biochemical research. For his PhD he chose to look at bacterial resistance to beta-lactam antibiotics. In that time he characterised two metallo beta-lactamases and studied their mechanism of action using cryoenzymology. On completion of his PhD he studied the mechanism of the zinc metalloenzyme  angiotensin converting enzyme  (ACE) with Bert Vallee at Harvard Medical School. It was during this time that the ACE inhibitors captopril and enalopril were discovered and high blood pressure ceased to be a major clinical problem. At the time Vallee and Folkman were trying to isolate a putative angiogenic factor and because of his protein expertise he asked Vallee if he could join the team. Angiogenesis was to be his main interest for the next 30 years and remains so today.

In 1989 he moved back to Oxford to set up the Angiogenesis Group of the Imperial Cancer Research Fund in the newly built Institute of Molecular Medicine.  Roy's work involved many studies on the newly identified vascular endothelial growth factor (VEGF) as well as other angiogenic factors. He was awarded tenure in 2004. These years led to some of his most highly cited papers including one that has over a thousand citations. That work showed that nitric oxide is essential for VEGF but not fibroblast growth factor induced angiogenesis. For the first time we realised that there is not just one mechanism of angiogenesis. With the rise of genomics Roy became interested in the identification of new endothelial genes. The first was delta-like 4 that was independently identified by three groups (one being led by a former PhD student of his). Later came Robo4 that he worked on for several years. Robo4 is the only endothelial specific roundabout gene and was an interesting finding for it showed that all four of the known neuronal guidance pathways have homologues in the endothelial cell involved in angiogenesis. In 2004 he was appointed Professor of Cancer Cell Biology in Oxford.

In 2005 Roy was recruited to Birmingham and started a five-year Cancer Research UK programme working together with Victoria Heath. They were still interested in novel endothelial genes but focussed on finding those that had potential as targets in tumour vessels. This led to the discovery of C-type lectin 14A (CLEC14A). CLEC14A expression is regulated by shear stress. Low shear stress induces expression and this leads to significantly higher expression in tumour vessels (due to poor blood flow) than in those in healthy tissues. Our work on CLEC14A has taken two paths. The first is to understand its function and the second is to develop it as a target. It is clearly involved in angiogenesis and we recently characterised the interaction with its ligand multimerin-2 (MMRN2) and showed that it forms a 'supercomplex' in which multimerin2 also binds the related endosialin and CD93. We plan now to study the functional consequences and interactions of this complex. For targeting they work with Steve Lee on CAR modified T cells (funded by the cell therapy catapult) and with several companies on antibody drug conjugates. Our final interest is in developing vaccines that target the tumour vasculature.

• Lectures and small group teaching for cancer and cardiovascular science to MBChB and Biomedical Sciences.
• Lectures in BMedSci year 3 modules in cancer, vascular biology and inflammation.
• Lectures on multiple MRes and MSc courses.

Roy has successfully supervised 50 PhD students to date. He currently supervises 6 students but is actively looking for new students. He is particularly interested in supervising doctoral research students in the following areas:

Elucidating the mechanisms by which multimerin-2 and it ligands CLEC14A, CD93 and endosialin mediate angiogenesis. We would like to focus on the extracellular protein interactions and intracellular signalling.

Development of a cancer vaccine using conjugate proteins.

Study of MCAM and its role in renal cancer. Use as a vascular target in mouse models of cancer.

Research Themes

• Angiogenesis
• Endothelial biology and vascular targeting of anti-cancer therapies
• Cell surface receptors and Imaging
• Targeted therapies including CAR modified T cells, antibody drug conjugates and vaccines

Our research focuses on the endothelial cell and endothelial genes that act either as targets or play a role in angiogenesis. We are particularly interested in the type 14 family of C-type lectins that includes CLEC14A, CD93 and endosialin and their common ligand multimerin-2. We are also interested in MCAM as a target in renal cancer and von Hippel Lindau induced renal cancer. We use a wide variety  of techniques from basic cell and molecular biology through to animal models of cancer and mouse transgenesis.
