About

I am Associate Professor at the School of Computing and Information Technology, University of Wollongong, NSW, Australia. My research focuses on public-key cryptography and network security. I was/am ARC DECRA Fellow (2017-2019) and ARC Future Fellow (2023-2026). I received my B.S. and M.S. degrees from Fujian Normal University in China (2005, 2008), and completed my PhD at the University of Wollongong in 2013.
