Prof. Davies' research interests lie in the mechanisms of protein modification by reactive species (radicals, two-electron oxidants, glycation reactions), the biological consequences of such reactions, and the development of methods to quantify protein damage in disease with a particular emphasis on cardiovascular pathologies.
He has interests in peroxidase enzymes (particularly myeloperoxidase), LC-MS (proteomic) detection, identification, characterization and quantification of protein modifications, EPR spectroscopy for the detection of transient radicals, the kinetics of oxidant reactions, extracellular matrix damage and the development of antioxidants and inhibitors of oxidant formation.
