My research interests fall at the interface of chemistry and biology focusing on studies of bioactive molecules including, synthesis, interactions with biomolecules and drug delivery. The focus of my PhD thesis was the multistep synthesis of natural products (azaspiracid-3) and molecular recognition studies of barbiturates. As a postdoctoral researcher, I studied the resistance mechanisms of HIV-1 integrase inhibitors and revealed a two-way binding mode of the first FDA approved integrase inhibitor, raltegravir. The results of this study received the first award at the 7th European HIV Drug Resistance Workshop and published in Biochemistry as a rapid report that was characterised as one of the 10 most accessed rapid reports in 2009. I later became interested in the human proteasome and developed a computational protocol to study the factors that confer subunit selectivity to proteasome inhibitors and opened the prospect of collaboration with pharmaceutical companies. A current research project includes the evaluation of argyrin analogues as inhibitors of the proteasome and immunoproteasome by using molecular modelling and in vitro assays.
Another research area of interest is the transdermal delivery of highly potent therapeutics using microneedles. This project involves an exploration of microfabrication techniques for the preparation of microneedles, imaging techniques for evaluating skin penetration, drug delivery studies and finite element analyses for the structural characterization of the microneedles.
