Dr. Jong Boon Ooi (Jacob) is a Senior Lecturer in Mechanical Engineering at the School of Engineering, Monash University Malaysia. He holds a PhD from Monash University Malaysia (2017), a Master of Engineering Science, and a Bachelor's Degree (Hons) in Mechanical Engineering, both from Universiti Tunku Abdul Rahman (UTAR). He is a Professional Engineer registered with the Board of Engineers Malaysia (BEM) and a Chartered Engineer with the Engineering Council, UK, as well as a Member of the Institution of Mechanical Engineers (IMechE), UK.

His research spans advanced nanomaterials including carbon-based and boron-based nanoparticles as fuel additives to enhance combustion performance, alongside the development of low-carbon fuel blends derived from renewable sources such as vegetable oils, agricultural waste, tires, and plastics. He applies machine learning, response surface methodology, and genetic algorithms to optimise fuel formulations and engine operating conditions. His fundamental combustion research encompasses experimental and computational studies of co-flow and counterflow diffusion flames, with a focus on flame structure, stability, and pollutant emissions using low-carbon fuels such as hydrogen, ammonia, synthetic methane, and biogas. His work is further enriched by integrated energy, exergy, economic, environmental, and life-cycle assessment frameworks aimed at advancing cleaner and more sustainable energy solutions.

Dr. Ooi has authored and co-authored over 38 international journal papers and secured research funding from competitive sources including Petronas Research, the Air Force Office of Scientific Research (AFOSR), the Fundamental Research Grant Scheme (FRGS), and various industry partners. He serves as an Editorial Board Member for Scientific Reports (Springer Nature), Discover Energy (Springer Nature), and Energy Research Journal, and as an Early Career Researcher Expert for Oxford Open Energy (Oxford University Press). He has also reviewed over 40 articles for leading journals in the fields of biofuels, combustion, and renewable energy.

In addition to his research, Dr. Ooi is deeply committed to education and student development. He has received multiple teaching excellence awards, including the Dean's Education Excellence Award 2025 from Monash University for outstanding contributions to student learning, and has consistently achieved near-perfect student satisfaction ratings across his units. He currently serves as Course Director for the Bachelor of Sustainable Energy Technology and Final Year Project Chief Examiner at the School of Engineering, Monash University Malaysia. He is also an Adjunct Professor at UCSI University and an active committee member of the IMechE Malaysia Branch.
