Vijay’s current project involves using nanoparticle contrast agent for NIR Photothermal Optical Coherence Tomography (PT-OCT). Objectives of the project includes, (a) optothermal simulations of NIR gold nanoparticles to investigate nanoparticles’ photothermal efficacy by finite element method using COMSOL Multiphysics and DEVICE, and (b) analysis of phase change due to photothermal property of gold nanoparticles embedded phantoms using  Photothermal Optical Coherence Tomography (PT-OCT). He is also involved in coordinating research collaboration among research groups in Europe for multiple EU research grants. Vijay received his Ph.D. in Applied Physics (Nanobiophotonics) in 2016 from NUI, Galway specialising in developing nanoprobes for multimodal imaging and therapy of cancer. He earlier obtained his Master’s degree from Western Sydney University, Australia in Biotechnology specialising in developing novel fluorescent sensor to detect DNA amplification in real time polymerase chain reaction (RT-PCR).
