About Me

I received my PhD from Queensland University of Technology, Australia. I graduated from the University of Peradeniya with an honours degree for specializing Physics in October 2011. Then I successfully obtained a PhD position in Plasmonics Device Group at QUT in 2012. My PhD project is about studying the interaction between Quantum dot and plasmon supported by plasmonic waveguides which include nanofabrication, characterization and testing.

Positions Held

Secretary, Departmental Committee, Department of Physics - (2017)

department representative - Student Welfare Advisory Committee - (2020- present)

Ongoing Research and Projects

Synthesis of colloidal quantum dots for Infra-red photo-detection

Improve IR sensitive quantum dot performances to achieve efficient photodetection in mid-wave IR region

Plasmon enhanced dye sensitized solar cells

We expect to enhance DSSC efficiency by modifying photo-anode using nanowires and Ag/AgBr/TiO2 nanocomposite

waste water treatment using magnetic Fe@MgO nanoparticles

Our aim is to use recyclable magnetic Fe@MgO nanoparticles to efficiently remove Pb (II) ions from waste water.

Develop self cleaning nanocomposite coating on clay roofing tile
