His research focuses on the following areas:
•Medicinal Inorganic Chemistry
•Molecular recognition and self-assembly
Synthesis of metal-containing drugs and study of their interactions with
DNA (as potential anticancer drugs) and proteins (as inhibitors of phosphatases).
Development of metal-containing probes for biomedical imaging (MRI and optical)
Organometallic chemistry of palladium (cross-coupling reactions, development of fast chemical processes for PET labelling)
Development of receptors for selective recognition of anions (phosphate, chloride, arsenate) and cations (mercury, lead) for the development of chemical sensors
Anion templated synthesis of supramolecular assemblies

"Targeting DNA with small molecules for imaging and therapeutic applications"
DNA can assemble in a wide range of different topologies such as Z-DNA, triplexes and quadruplexes. With the mounting evidence that several of these non-canonical DNA structures play key biological roles, there is increasing interest in developing small molecules that can interact selectively with a given topology. In particular, over the past few years there has been increasing interest in the development of selective binders for guanine-quadruplexes (G-quadruplexes). G-quadruplex DNA has been shown to play important roles in regulation of gene expression, telomere maintenance and replication and therefore have been proposed to be attractive anticancer drug targets. This lecture will focus on the use of molecular tools to help us understand the biological roles of G-quadruplexes as well as their potential as drug targets.
