Dr. Wei Wen Wong received his B. Eng. (Hons) degree in electronics engineering majoring in Nanotechnology from Multimedia University, Selangor, Malaysia, in 2016. From 2016 to 2018, he worked as a Failure Analysis Engineer in Cypress Semiconductor in Malaysia. He obtained his PhD degree at the Australian National University (ANU) in 2022 under the supervision of Professor Hoe Tan and Professor Chennupati Jagadish, working on the selective area epitaxy of III-V micro-ring lasers for optoelectronic applications. He is currently working as a postdoctoral fellow at the Department of Electronic Materials Engineering, Research School of Physics, ANU. His current research interests include the growth and characterisation of low-dimensional compound semiconductors, design and fabrication of novel nano-lasers, and the development of bottom-up, on-chip micro-cavity lasers.
