Senior Research Fellow

Dr Zhaojun Han

Ph.D, Nanyang Technological University, Singapore

B. Eng., Nanyang Technological University, Singapore

School of Chemical Engineering

Dr Han's research focuses on developing functional nanomaterials for energy storage and conversion, nanomaterials, plasma nanofabrication, electrochemistry, and advanced catalysts for hydrogen and CO2 reduction.

Dr. Han is an expert in vertical graphene, a special form of graphene that grows perpendicularly to the substrate. Vertical graphene can prevent the “re-stacking” issue of graphene layers, thereby enabling fast ion transport and large surface accessibility in energy storage devices. He has implemented vertical graphene for batteries and supercapacitors to offer highly-effective and reliable energy storage, as well as advanced electrocatalysts for low-cost and high-efficiency water splitting and CO2 reduction.

He is currently a Senior Lecturer at

  • School of Chemical Engineering

  • School of Mechanical and Manufacturing Engineering

He received 

  • PhD degree in 2009 from School of Electrical and Electronic Engineering (EEE), Nanyang Technological University, Singapore. His PhD studies focused on fabricating conductive polymer nanocomposites using plasma-immersion ion implantation (PIII) technique.

  • B. Eng degree in 2004 from School of Electrical and Electronic Engineering (EEE), Nanyang Technological University, Singapore.

During 2009-2012, Dr Han was the Office of Chief Executive (OCE) postdoctoral fellow at CSIRO, Lindfield. His postdoctoral research was on the synthesis and applications of carbon nanomaterials such as carbon nanotubes and graphene.

He then became Research Scientist and Senior Research Scientist in 2012 and 2015, respectively, with the research oriented to energy storage devices such as supercapacitors and batteries.

Since 2019, Dr Han has held 

  • Part-time (50%) Senior Lecturer at School of Chemical Engineering and School of Mechanical and Manufacturing Engineering, UNSW Sydney.

  • Part-time (50%) Senior Research Scientist at CSIRO, Lindfield.
