| Biography |
Andy Khong is currently an Assistant Professor in the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore. Prior to that, he obtained his Ph.D ('02-'05) from the Department of Electrical and Electronic Engineering, Imperial College London, after which he also served as a research associate ('05-'08) in the same department. He obtained his B.Eng in Nanyang Technological University in Singapore.
His postdoctoral research involved in developing 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 telephony. He has also published works on acoustic blind channel identification for speech dereverberation. His other research interests include speech enhancement and blind deconvolution algorithms. He was the recipient of the best student paper award at the International Workshop on Acoustic Echo and Noise Control 2005. |
