Computational Drug Design.
We are interested in developing and applying computational methods to drug design. Methods range from rigorous alchemical thermodynamic calculations through to machine learning. Where possible the calculations are linked to ongoing work in Oxford or industrial partners.

Bionanotechnology for intelligent cell activation and vaccination.
Particular projects include solid-phase synthesis of polypeptide teams, for controlled triggering of cancer cell death or magnetic cancer cell capture for early diagnosis; also adapting auto-catalysed amide bond formation from bacteria to make “protein superglues” to engineer viral particles for new kinds of vaccine. Techniques that may be used: chemical modification of proteins, cell culture, fluorescence microscopy, mass spectrometry, DNA manipulation (PCR, cloning, mutagenesis), protein design and evolution, X-ray crystallography.

My group seeks to develop novel inhibitors against key enzymes of the malaria parasite. We are interested in targeting enzymes involved in a broad range of parasite functions, including chaperone proteins that enhance malaria virulence and enzymes involved in haemoglobin digestion by the parasite. We are structural biologists and biochemists, primarily using X-ray crystallography and solution-state NMR to understand these enzymes at the atomic level, and then developing in vitro biochemical assays of function. We collaborate with Oxford-based high-throughput pipelines (XChem and OxXChem) and an industrial partner (CloudPharm) for the in vitro and in silico identification and development of small molecules binding to our enzymatic targets, once the enzyme structure is elucidated.
