Welcome

For one reason or another, you are now visiting my homepage. I was born in a small town located in the northern region of Malaysia, and attending my primary and secondary schools there. Partly due to science fiction, I was fascinated by how science and engineering contribute to and improve human life. To pursue my ambitions, I spent a few years in University Technology Malaysia and Nanyang Technological University, Singapore, for my under-graduate and postgraduate studies.

My Ph.D. research work was on subband adaptive algorithms for high-order transversal filters, under the supervision of Prof. Woon Seng Gan. We proposed the Normalized Subband Adaptive Filter (NSAF), which is computationally efficient and proven to be extremely effective in dealing with colored excitation signals. Such algorithm is useful, for examples, in acoustic echo cancellation (AEC) and wideband active noise control (ANC) applications.

I am currently a Senior Principal Researcher at Data Science Research Laboratories, NEC Corporation, Japan. From 2006 to 2018, I was a research scientist at the Human Language Technology Department, Institute for Infocomm Research (I2R), A*STAR, Singapore. My current research interests include speaker recognition and characterization, multilingual recognition and identification, speech analysis and processing, machine learning and digital signal processing. I also serve as an Editorial Board Member for Elsevier Computer Speech and Language, and Associate Editor for IEEE/ACM Transactions on Audio, Speech and Language Processing. Our work on commercializing speaker recognition technology for mobile devices leads us to the IES Prestigious Engineering Achievement Award 2013.
