His research interests are best summarised as “molecular imaging” mainly using inorganic chemistry tools. Most recently he has begun to focus on use of PET to study metallomics and in vivo cell tracking. As Head of the Imaging Chemistry and Biology Dept, he has built a large interdisciplinary research group with wide interests covering radiopharmaceutical chemistry and biology for PET, SPECT and radionuclide therapy, applying inorganic chemistry from all parts of the periodic table to nuclear medicine. He has published >180 peer-reviewed papers and supervised 33 successful PhD students.
