Research interests
Chemistry of metals in medicine (bioinorganic chemistry, inorganic chemical biology and medicine).

Design and chemical mechanism of action of therapeutic metal complexes, including organometallic arene anticancer complexes, photoactivated metal anticancer complexes (for photochemotherapy), metallomacrocycles as antivirals and stem-cell-mobilising agents, and metalloantibiotics.

Besides synthesis of co-ordination complexes, research involves studies of interactions with targets such as RNA, DNA and proteins, and often industrial and international interdisciplinary collaborations.
