I am current a Senior Researcher in III-V Materials and Devices group in Tyndall. As a principal investigator funded by Research Ireland, I lead a research team focusing on visible light emitting devices and the advanced intergration. I am the coordinator of the Horizon Europe project (Acronym: SLDAR), managing a EU consortium comprising of partners from 7 countries. Also is a co-PI in the newly established Ireland Semiconductor research centre, coordinating activities in a sub-theme on visible light platforms.

Before joining Tyndall, I received full funding from the Faculty of Engineering in the University of Sheffield pursuing my PhD degree from 2014 to 2018, where my research field was about the semi-polar and non-polar III-nitrides epitaxy using metal-organic chemical vapour deposition (MOCVD) for high efficiency light emitters. Prior to that, I completed Master studies focusing on the InGaN-based LEDs fabrication and characterization in the Institute of Semiconductors, Chinese Academy of Sciences from 2011 to 2014, during which I visited Taiwan University for academic exchange for 6 months. I received the Bachelor degree from University of Science and Technology Beijing in 2011.

My research interests lie mainly on the III-nitride based materials (GaN, InGaN, AlGaN), photonic devices (LEDs, SLDs and LDs) and their applications. Particularly, I am interested in the micro-LEDs, and the applications for microdisplays as well as high-speed optical links (visible light communication).

I am also interseted in the heterogenous integration of visible lasers in photonics integrated circuits (PICs). My expertise includes the micro-transfer printing technologies of III-V devices, which allows to assemble different components (lasers and waveguides for example) into one platform. This integration can be applied to many applications including AR/VR displays, sensing, etc...
