is currently an Associate Professor in the
School of Electrical and Electronic
Technological University, Singapore. Prior to that, he
obtained his Ph.D. ('02-'05) from the
Department of Electrical and
Imperial College London, after which he also served as a
research associate ('05-'08) in the same department. He
obtained his B.Eng. ('98-'02) in Nanyang Technological
University in Singapore.
His postdoctoral research
involved the development of signal processing algorithms for vehicle destination inference as well as the
design and implementation of acoustic array and seismic
fusion algorithms for perimeter security systems. His Ph.D. research was mainly on partial-update and
selective-tap adaptive algorithms with applications to mono-
and multi-channel acoustic echo cancellation for hands-free
He has also published works on speech enhancement, multi-channel microphone array and blind deconvolution algorithms. His other research interest include education data mining, machine learning applied to education data.
Andy currently serves as an Associate Editor for the IEEE Trans. Audio, Speech and Language Processing and the Journal of Multidimensional Systems and Signal Processing (Springer). He was a visiting professor at UIUC in 2012 under the Tan Chin Tuan Fellowship. He is the author and co-author of two papers awarded the "Best Student Paper Awards" and is a receipient of the Junior Chambers International "Ten Outstanding Young Persons Honouree Award 2011" and the Institute of Singapore "Prestigious Engineering Achievement Award 2012."
