Wong Wei Ru received her Ph.D. and B.Eng. degrees from Department of Electrical Engineering, University of Malaya, Malaysia. After her Ph.D. graduation, she worked as a post-doc at Integrated Lightwave Research Group, University of Malaya. She is currently a Senior Lecturer at the Department of Electrical Engineering, University of Malaya.

Her Ph.D. thesis involved the development of long-range surface plasmon based biosensor for dengue detection. During her PhD, she was sent to University of Ottawa, Canada as a visiting student under the Berini’s group for 2 years. The collaborative research on dengue detection with the University of Ottawa was featured in reputable high impact journals and media, including Nature, Science, and Laser Focus World. In 2015, her research named “Using Light to Diagnose Disease” has been selected as one of the six significant research projects featured under the “Defy the Conventional” campaign organized by University of Ottawa. In 2016, this research project on dengue biosensor was awarded a funding worth close to RM 2mil for commercialization purpose. She was the recipient of Malaysia Toray Science Foundation (MTSF) Science and Technology Award in 2017 and University of Malaya’s Excellent Service Certificate (SPC) in 2018. In 2020, she was one of the 20 honourees of the MIT Technology Review Innovators Under 35 Asia Pacific competition.

Being a junior researcher, her research interests span widely across the photonics areas, especially in the development of planar waveguides and optical fibers using surface plasmon for sensing applications. She has published more than 40 top quality internationally refereed journal papers.
