Dr. Koh Kai Seng obtained his B(Eng) degree in Chemical Engineering from The University of Nottingham Malaysia campus. He immediately conducted his Ph.D. research and was rewarded his Ph.D degree in Engineering at The University of Nottingham Malaysia Campus. His dissertation focuses on synthesis and characterization of an energetic solution, hydroxylammonium nitrate (HAN) and study of decomposition effect of the solution using electrolysis in macro- and micro-scale.

Before joining Heriot-Watt University Malaysia, Dr. Koh served as a visiting assistant professor in the University of Nottingham Ningbo campus, China. Dr. Koh has a broad range of academic interests including microscale fluid dynamics, multiphase flow, MEMS device packaging of design and fabrication, energetic material synthesis and characterization, as well as life science application using the technology of droplet microfluidics. He was able to secure 3 research grants which worth more than RM300,000.

Currently at Heriot-Watt, Dr. Koh is the module conveyor for

  • B19AB Chemistry of Materials for Chemical Engineers
  • B48BA Process Industries C
  • B48 BE Process Design A
  • B40 DC Energy Generation and Utilisation
