Motor Driven Systems, Audit and Analysis

Dr. Lock is a Professor (Engineering) at the Singapore Institute of Technology (SIT) and the Head of its Energy Efficiency Technology Centre. He plays an active role in energy efficiency and sustainability, being the Chairman of Accreditation Committee for Energy Service Companies (ESCOs) and the Co-Chair of Steering Committee of Singapore Certified Energy Managers (SCEM) Scheme. 

He has a unique blend of practicing and academic experience acquired through a career which is equally split between the industry and the academia. He received both his B.Sc. (1975) and Ph.D. (1979) degrees in Electrical Engineering from the University of Strathclyde, UK. He was a faculty at the Department of Electrical Engineering, National University of Singapore for 17 years when he left to set up his consulting practice in 1997. He returned to the academia as a professor at SIT in 2016 after 20 years in the industry.

He is a specialist consulting engineer in the areas of mission-critical electrical design, power quality, EMC, and electrical safety. He is well-sought for advice on challenging electrical problems, including commercial & industrial electrical systems and offshore platforms. He was involved in the review and performance assessment of large thruster drives for deep sea drilling platforms. He has also consulted for many projects on simulation, measurement and mitigation of harmonic problems associated with variable speed drives (VFD). He has conducted failure investigations on motors/drives for application in process plants, air-con system, water treatment plant and semisubmersible rigs, including role as expert evaluator/witness in disputes.

He is a registered Professional Engineer (Electrical), a Fellow of Academy of Engineering Singapore and an Honorary Fellow of the Institution of Engineers Singapore.

Dr. Sivakumar Nadarajan joined SIT in July 2024, he obtained his PhD in electrical engineering from National University of Singapore, Singapore in 2016. Prior to SIT, he worked in Rolls-Royce, Singapore for 15 years as a technical manager and Head of CoE – Electrical equipment heath monitoring. He has accumulated around 19 years of industrial experiences from aerospace, marine, automotive, and other industrial sectors. He also worked as a lecturer in an Anna university affiliated college in Chennai, India, for a year where he thought electrical engineering modules for undergraduate and post graduate students, his research interests primarily in the field of condition monitoring and failure prognosis of safety and mission critical applications, architect safety critical electrical systems, applied AI for prognostic health management, fault tolerant electrical machines, medium fidelity modelling and simulation, and electrical drives.

Dr. Nadarajan has filed 40 patents in USA and Europe, and published over 50 research papers in international journals and conferences. He is a certified chartered engineer by Institute of Engineering and Technology (IET), UK. He also recognised with various awards for his innovation and technology development, received the 2023 ASEAN outstanding engineering achievement award from AFEO, the 2023 IES prestigious engineering award from IES, Singapore, and also received the Sir Henry Royce awards for innovation and engineering excellence from Rolls-Royce Plc.

Dr Shuyu Cao received Ph.D. degree in Electrical and Electronic Engineering from Nanyang Technological University (NTU), Singapore. She received B.Eng. and M.Eng degrees in Electrical Drive and Industry Automation Engineering from Tianjin University, China. She is currently a lead professional officer at Singapore Institute of Technology (SIT). Prior to joining SIT, she has worked as a senior research fellow in Energy Research Institute of NTU in Singapore, as a servo control manager at Western Digital Singapore HDD R&D Center, as an associate principal engineer in wind turbine converter control at Vestas R&D Singapore, as a staff servo control engineer in Seagate Singapore HDD R&D Center, and as a senior electronic design engineer in Tianjin Research and Design Institute of Electrical Drive (TRIED) in Tianjin City, China.
