Dr Heow Pueh Lee is a Professor and the Deputy Head for Research at the Department of Mechanical Engineering, College of Design and Engineering, National University of Singapore. He obtained his Bachelor degree from the University of Cambridge, Master of Engineering from the National University of Singapore, Master of Science and PhD from Stanford University. He was seconded to the Institute of High Performance Computing, Agency for Science, Technology and Research from 2002 to 2007 as the Deputy Executive Director for Research. He was a recipient of the Singapore Minister for National Development’s R&D Awards 2017 (Merit Award). The design of cantilevered jagged-edge noise barriers can be found in many construction sites along the new Thomson-East Coast Line of the Mass Rapid Transit system. His research efforts concentrate on characterization of sound and the design of acoustic meta-structures (manmade and non-existence in nature), in particular for low frequency regime where existing acoustic mitigation solutions fail. While he emphasizes on new insights of meta-materials designs from physics-based approaches, he also actively pursues the potential applications of technology for mitigation of environmental noise in densely populated cities. His is an Associate Editor for Applied Acoustics (Elsevier), and Member of Editorial Board for Acta Mechanica Sinica (Springer), International Journal of Applied Mechanics (World Scientific), Design (MDPI), and Acoustics (MDPI).
