About me

Benjamin Ung received a PhD in Electrical and Electronic Engineering in Terahertz Spectroscopy in 2013, during which time he was a postdoctoral research fellow in Prof Emma MacPherson’s Terahertz group at the Chinese University of Hong Kong until 2016. He then returned to Australia and was a Product Specialist at Carl Zeiss Microscopy Australia until 2019, when he joined the Mechanisms in Cell Biology and Disease Research Group under Prof Doug Brooks at UniSA as a Research Fellow. Ben also has a B.Eng. degree (Honors) in Computer Systems Engineering and the B.Sci. degree in Mathematics and Computer Science from the University of Adelaide, in 2005. Currently, Ben is with the Quality Use of Medicines and Pharmacy Research Centre... Read more
