BSc(Hons), PhD (University of Auckland)


Our group is interested in the way molecules and nanoparticles self-organise into functional architectures. We are currently introducing responsive elements into systems that allow them to respond to light, transmit signals and demonstrate adaptive properties. Such systems offer exciting possibilities for the development of molecular machines, smart materials and molecular electronics.

I conducted my PhD at the University of Auckland with Prof. Margaret Brimble, working on the synthesis of spirastrellolide B - a potent protein phosphatase inhibitor with potential anti-cancer properties. I then took up a Postdoctoral Fellow appointment in the same group for 18 months, and was involved in a range of projects including the total synthesis of bioactive molecules from traditional Chinese medicines and a medicinal chemistry project to discover novel telomerase inhibitors. In 2011 I moved to Bristol, UK, for 3 years where I worked with Prof. Varinder Aggarwal developing synthetic methodology involving a novel form of activated allylboron reagents. In 2014 I took up a Postdoctoral Fellowship with Prof. Leonard Prins in Padova, Italy, where I studied the use of gold nanoparticle-based supramolecular systems for chiral catalysis. In July 2016 I joined the staff at the School of Science at AUT.

Dynamic self-assembled systems responsive to external stimuli

Our group is interested in the way molecules and nanoparticles self-organise into functional architectures. We are currently utilising self-assembly to construct dynamic structures that possess emergent properties. This is possible by utilising cooperative effects - where multiple functional groups work together to exhibit properties that are not observed in the original building blocks. Such dynamic systems allow the introduction of stimuli-responsive moieties that allow these systems to respond to chemical fuels, light and other external stimuli. Such responsive systems offer exciting possibilities for the development of molecular machines, smart materials and molecular electronics.

Sustainable chemistry in water catalysed by multi-functional gold nanoparticles

In the current battle against climate change, chemists have an even greater responsibility to conduct chemistry with low environmental impact. This means following green chemistry principles such as utilising catalysis and minimising waste. The proposed project aims to immobilise catalysts onto gold nanoparticles which are water soluble, creating catalysts which are effective in water, and which are easily recyclable. How different immobilisation methods affect the kinetics and mechanisms of different reactions will be studied. Reactions of interest include ester formation driven by phase separation, the kinetic resolution of terminal epoxides and aldol reactions catalysed by proline-based organocatalysts. The immobilisation of multiple catalysts will also enable the development of cascade reaction methodology, another important goal in green and sustainable chemistry.
