Koay Teong Beng

Research Fellow

Teong Beng received his bachelor of engineering (BEng) in electrical and electronics engineering from Universiti Teknologi Malaysia followed by his Master of Engineering (MEng) in electrical and computer engineering from National University of Singapore. He enjoyed the R&D environment and the freedom in designing and building custom instrumentation that supported various researches in ARL. He has been leading designs of the hardware in many of the projects such as the stochastic tomography experiment, ROMANIS, high frequency ambient noise studies, mini PANDA, cPANDA used for humpback whale studies, acoustic bandwidth compression system, and recently involved in STARFISH, dPod, and modem development.
