Ji Jinn Foo is a Senior Lecturer in Mechanical Engineering in the School of Engineering at Monash University Malaysia. He received his Bachelor of Science and Master of Science degrees in Mechanical Engineering from National Chung Cheng University in Taiwan in 1998 and 2000, respectively, and his PhD in Mechanical Engineering from Nanyang Technological University in Singapore in 2004. Following his PhD, he was a Postdoctoral Fellow at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany, from 2004 to 2008. Foo began his academic career at SEGi University in Malaysia in 2008, where he advanced to Associate Professor and Director of the Research & Innovation Management Centre by 2012. Since 2013, he has been a Senior Lecturer at Monash University Malaysia.
Foo's research focuses on novel heat transfer methods that employ insert-induced fluid flow fluctuations for thermal dissipation via forced convective or natural convective heat transfer. A key aspect of his work involves using planar fractal geometry to generate turbulence, capitalizing on its ability to produce higher turbulence intensities and rescalable flow frequencies across various characteristic length scales, thereby enhancing diffusivity, mixing, and transport of mass, momentum, and energy. His group investigates grid inserts to augment heat transfer, with projects funded by the Malaysian Ministry of Higher Education's Fundamental Research Grant Scheme and in collaboration with Daikin R&D. Selected publications include "Augmentation of piezoelectric thin-film flapping velocimetry turbulence strength detection via machine learning" (2025), "Heat transfer performance and fouling analysis of clove-treated graphene nanoplatelet nanofluid in a double-pipe heat exchanger" (2025), "Lattice Boltzmann-based microchannel concentration mixing with surface roughness-mediated flow dynamics" (2025), "A Computational Study on the Use of Phase Shift to Improve Dual-frequency Sonothrombolysis Outcomes" (2024), "Comparisons of Sequential and Simultaneous Acid–Base Injections During Thermochemical Ablation: A Computational Study" (2024), "Fractal cube-induced homogenisation of dual concentration microchannel flow in transitional Re: Lattice Boltzmann modelling" (2024), and "Fractal grid-induced turbulence strength characterization via piezoelectric thin-film flapping velocimetry" (2021).
