My research group develops new materials for next generation solar cells and for biosensors.

Our main research focus using ultrafast optical spectroscopy to elucidate photophysical processes in materials including pi conjugated molecules and polymers, nanocrystals and organometal halide perovskites. This work contributes to the design of efficient next generation solar cells. The Ultrafast Laser Spectroscopy Research Group provides more information about the methods that we are developing and using for probing the optoelectronic functionality of such materials.

A second research area is biotemplated assembly of organic semiconductors. We have recently developed a class of hybrid materials that use natural peptides to encode the assembly of organic semiconductors into functional electronic devices.

Our third research focus is developing biosensors that use DNA aptamers as the recognition element. We have developed a range of sensors that are selective for the sex hormone 17b-estradiol, producing a strong colour change or electronic signal in the presence of extremely low concentrations of the hormone.

Students can be involved in all aspects of this research, including:

  • application of ultrafast optical spectroscopy to probe photofunctional materials
  • development of new ultrafast spectroscopy tools
  • peptide-directed self assembly of nanostructured functional materials
  • development of DNA aptasensors.

I am a principal investigator in the MacDiarmid Institute for Advanced Materials and Nanotechnology, where I contribute to the theme of materials for energy capture and utilization. My research also involves collaborations with several other research groups at Victoria University of Wellington, around New Zealand, and around the world.
