I was born and raised in Guangzhou, China. I obtained my bachelor degree in computer and electrical engineering at University of Toronto, Canada. I obtained my master degree in the same university, with a focus on reconfigurable antenna design for satellite communication. Currently I am pursuing my PhD study at TU Delft, Netherlands in the area of passive light communication.

Outside of academia, I have a completely normal obsession with horror movies.

Visible light communication has been primarily exploited to communicate actively: control over the light source is required. My project focuses on the area of passive visible light communication. Modulating a lot of light sources, like the sunlight, is impossible, instead we will use smart surfaces to modulate the incident light signals by altering their properties between reflective and absorbing states (e.g. with materials such as eInk, LCD shutters or smart glass) or different reflective states (e.g. with digital micromirror devices).

My project aims to improve the performance of passive visible light communication systems on metrics such as modulation speed, range and capacity. This will be achieved through a combination of hardware prototyping with different devices, as well as developing analytical models to optimize the placement and configuration of transmitters and receivers in the system.
