Research Interests

Overview

The central theme of my research lies in the advancement of new strategies for the synthesis and functional assessment of structurally complex molecules. Specific goals include the development of new light activated anti-cancer and anti-microbial agents, the investigation of novel concepts for drug selectivity and the generation of chemical tools to assist in gaining a molecular level insight into biological processes. My research has its foundations in medicinal organic chemistry and chemical biology with strong collaborative links with biological imaging and medicine.

On-going Research Projects (Details of on-going Research Projects)

Near-infrared fluorochromes for real-time in vitro and in vivo imaging; tools for chemical biology and fluorescence guided surgery.
A new class of photodynamic therapeutic agent with anti-cancer and anti-bacterial potential.
Innovative methodologies for pharmaceutical synthesis utilizing microflow reactors.
Mixed metal Li/K amides (LiNK chemistry) as new reagents for synthetic chemistry.

Research Group

Current Research Group:
Research group currently consists of four Ph.D. students and two postdoctoral researchers.

Students Graduated:
Fourteen PhD and three MSc students graduated to date.
