The main research focus of my group is on the optoelectronic properties of novel nanoscale semiconductor materials to deliver solutions for solar energy harvesting, optical switches, and polariton lasers. I am interested in:
- Harnessing chirality at a nanoscale and polarization of light to discover new optical phenomena
- Utilising strong light matter interactions via formation of polaitons to tune excitonic properties
- Molecular photophysics of semiconductor materials
