Ben started his research career at the National University of Singapore, and obtained his PhD of chemical and process engineering from the University of Canterbury. Afterwards, he undertook a Postdoctoral Fellowship at the Advanced Membranes & Porous Materials Center of the King Abdullah University of Science and Technology (KAUST), and led an industrial product R&D project in China. He returned to New Zealand with funding from the MacDiarmid Institute and worked at Massey University. He then worked as a research scientist at the New Zealand Institute for Minerals to Materials Research, until his current appointment at Victoria University of Wellington.
Ben's research interests span the creation of inorganic and organic materials and their applications in the environmental and energy industries. To be specific, Ben’s work includes 1) membrane separation process, 2) fabrication and applications of porous materials, e.g., metal-organic frameworks (MOFs), zeolite and advanced carbon materials, 3) hydrogen production and applications.
