Fascinated by the beauty and power of both physical and mathematical laws, I am humbly seeking a perfect blend of them in solving engineering problems elegantly and rigorously.

- Contributed important findings in three areas – receiver architectures, multiple-input and multiple-output transmitter optimised designs, and the rate-energy region for characterising performance trade-offs – in making the performance of radio signals for simultaneous wireless information and power transfer (SWIPT) possible and feasible, as well as devised a first-ever integrated information and energy receiver design
- Overturned the conventional view that wireless interference is detrimental to wireless information transmission in SWIPT, proving instead it could be a beneficial energy source
- Pioneered studies on optimally managing wireless communications with intermittent environmental energy sources, including the development of a “staircase” structure as an ideal power allocation scheme
- Built on his work on wireless communications with unstable energy sources to authenticate a significant "separation principle" for reducing the complexities involved
- Innovative and highly collaborative in pioneering interdisciplinary research on a promising unified study of wireless information and power transfer
- More than 3,500 citations received for over 50 papers, a phenomenally high figure among the world’s researchers in his field
- Several high-impact papers published in prestigious Institute of Electrical and Electronics Engineers (IEEE) journals rank among the journals’ top three most-cited
- Holds a Hirsch index of 40, indicating high research quality and impact
- A well-respected reviewer for over 10 of IEEE’s journals and 15 of its conferences
- Appointed as associate editor of IEEE Transactions on Wireless Communications and IEEE Transactions on Signal Processing
- A regular invited speaker at established and prestigious conferences worldwide
- 6th IEEE Communications Society Asia-Pacific Best Young Researcher Award (2011)
