Biography: Guanghui Ren is now a research fellow in the school of engineering at RMIT University. He received his PhD from RMIT University in 2016. His research is focusing on integrated optics, especially silicon photonics. He used silicon photonics as a platform to integrate different functional materials, such as 2D materials, chalcogenide, and plasmonic materials, to expand the capabilities of silicon photonics in the aspect of sensing, nonlinearity, modulation, et. al.
