BIOGRAPHY

Kelvin J. A. Ooi is an Associate Professor with the Xiamen University Malaysia Campus. He received his BEng (Hons.) and PhD degrees in Electrical and Electronic engineering, from Nanyang Technological University, Singapore, in 2010 and 2014, respectively. He has authored over 50 international journal and conference publications with a citation count of over 500 and h-index of 14. He has also received and presented 8 invited talks in international conferences. He is the recipient of several national and university research grants, and has secured over RM 300,000 in research funding (from the Ministry of Higher Education Malaysia under its Fundamental Research Grant Scheme (FRGS), and the XMUM Research Fund) as both Principal and Co-Investigators.

Prior to joining Xiamen University Malaysia, he served as a Postdoctoral Research Fellow, from 2013-2018, in the SUTD-MIT International Design Center, and also the Lee Kuan Yew Center for Innovative Cities, which are both located within Singapore University Technology and Design. He has worked on projects from various disciplines, which includes integrated optics design for optical computing and data transmission, as well as daylighting technologies for sustainable architecture design.

His current academic and research interests span interdisciplinary domains, primarily in the modelling of physical systems and its application to different domains of knowledge. He is presently investigating the physical models of urban traffic as well as neural propagation, and is interested to extend physical modelling to economics and social interactions. He is an active collaborator with scientists and researchers from different disciplines, including engineers, mathematicians, economists and social scientists.
