Thomas Y. Wu holds a Ph.D. in E.E. from Nanyang Technological University and M.S. and B.S. from Shandong University. He worked on passive radar imaging & tracking, statistical signal processing, and time delay estimation at Coordinated Science Lab, University of Illinois at Urbana-Champaign in 1998-2001.  He is currently a Lead Metrologist and Assistant Director in the Mechanical Metrology Department of National Metrology Centre (NMC), A*STAR. He developed the world first THz attenuation metrology standard up to 0.5 THz with high dynamic range in 2009-2011. His article on a 220-325 GHz phase-shift measurement was featured by IET Electronics Letters in 2012. He has over 20 years of experience across diverse metrology fields, including THz/microwave and AC electrical measurements, low-current, phase noise, thermal noise, gas mixture and purity analysis, LNG flow/density/energy measurement, aerosol particles, light scattering, displacement, laser interferometry, acoustics, ultrasound, vibration, rotation, force, measurement uncertainty, statistical analysis, etc. Dr Wu is a member of TC22 (vibration measurement) of IMEKO, observer member of CCAUV under CIPM, and a member of TCAUV under APMP.  He has also served as a peer reviewer for other National Metrology Institutes and as a  SAC Technical Assessor in electrical, mechanical, and chemical calibration areas. He was a member of the SAC TC for Proficiency Testing. He has published over 70 papers in journals and conferences.
