Research Experience<\/h1>\n
Department of Nuclear Science, University of Colombo (Senior Lecturer ,since 2016)<\/h3>\n
- Currently I am deeply involved in determining feasibility of prompt gamma imaging for passive-scatter proton radiotherapy treatments using a Geant4 Monte Carlo simulation collaborating with the department of Physics, University of Cape Town.<\/li>
- I am also supervising undergraduate and postgraduate research projects in medical physics<\/li>
- Visiting medical physicist at the Maharagama National Cancer Institute and Cancer Treatment Center Tellippalai.<\/li><\/ul>
Medical radiation division, iThemba LABS, South Africa (Doctoral Training (2012-2014)<\/h3>\n
- Measured the discrete prompt gamma-ray emissions from water, Perspex, graphite and liquid nitrogen targets irradiated by a clinical passive-scatter proton beam of 200 MeV for in-vivo range verification purposes<\/li><\/ul>
Department of Physics, University of Cape Town, South Africa (Doctoral Training (2012-2014)<\/h3>\n
- Developed a Monte Carlo model of the entire experimental setup including iThemba passive-scatter proton beam line and detector with GEANT4 Mone Carlo code.<\/li>
- Developed a Monte Carlo model for a new beam range monitor<\/li>
- Validated the existing GEANT4 low energy physics for the proton inelastic nuclear reaction against available experimental cross-section data<\/li>
- Assisted MSc student from the Department of Physics, University of Western Cape to learn GEANT4 programming as well as to develop a Monte Carlo model for the simulation of Rutherford scattering<\/li>
