Research interests

Controlled radical polymerization allows a control of polymer and nanoparticle architecture that was previously only dreamt of. Reversible addition fragmentation chain transfer (RAFT) is the most versatile of the currently available controlled radical processes. We exploit this new capability in our research to design and synthesize polymer particles and composite nanoparticles for a wide range of applications.

1. Disperse phase polymerization:

  • RAFT controlled radical polymerization
  • Emulsion polymerization kinetics and mechanisms
  • Preparation of composite nanoparticles.

2. Biomedical applications of magnetic nanoparticles:

  • Hyperthermia treatment of cancer
  • Targeted drug delivery
  • Medical Imaging.

3. Stabilization and rheological control of concentrated emulsions.

4. Improving the efficacy and performance of agrochemical actives.

5. Conducting collaborative projects with industry.

6. Ionic liquid ferrofluids for aerospace applications.

Current projects

  1. Preparation of composite nanoparticles for the enhancement of paint properties; with DuluxGroup (Australia) Pty Ltd.
  2. Improving the performance of explosive emulsions; with Dyno Nobel Asia Pacific Limited.
  3. Biomedical applications of sterically stabilised magnetic nanoparticles; with Sirtex Medical
  4. Ionic liquid ferrofluids for aerospace applications; with Michigan Tech and the US Air Force
  5. Enhancing the performance of Agrochemicals; With Syngenta Crop Protection
  6. Current PhD projects:
  • The particle size limits of the zero-one approximation in the kinetics of the emulsion polymerisation of styrene.
  • The preparation of polymeric Janus nanoparticles.
  • Polymeric nanoparticles in the treatment of kidney disease.
