I am a member of the Departments of Chemistry and Oncology and my research interests centre on nucleic acid chemistry and its applications. Our research relies on the synthesis of novel modified nucleic acids and analogues. Using X-ray crystallography and NMR we have studied the nature of base mispairing in DNA, the structure of DNA duplexes containing mutagenic lesions and the interaction of DNA with repair enzymes. We have developed rapid methods for the identification of mutations in the human genome such as Scorpions, which are used to analyse genomic DNA at single base resolution. Developed in collaboration with AstraZeneca, Scorpions were commercialised by DxS and Qiagen, and are used in companion diagnostics to match patients with the most suitable drugs. They have led to the clinical use of cancer therapies, which were previously rejected on the basis of limited efficacy. We also work on the chemical synthesis of oligonucleotide analogues for therapeutic applications and we are modifying CRISPR-based systems for cellular imaging and editing. We have developed a number of artificial DNA/RNA backbones that can be read through by polymerase enzymes and this led us to develop chemical methods of nucleic acid ligation and gene synthesis. I am the co-founder of three Biotech companies and I have published over 400 research papers. I am a Fellow of the Royal Society of Edinburgh, a Fellow of the Royal Society of Chemistry.
