ABOUT ME

I am a senior lecturer of the UNSW Institute for Cyber Security (IFCYBER) in the School of Engineering and Information System (SEIT) at the University of New South Wales (UNSW). Currently, I am also the postgraduate program coordinator of Cyber Security Operations in UNSW. Before joining UNSW, I was a lectuer in the School of Information Technology and Electrical Engineering (ITEE) at the University of Queensland (UQ). I received my Ph.D. degree in the School of Information System (SIS) from Singapore Management University (SMU) in 2018 and became a postdoctoral research fellow in Data61, CSIRO. I visited Carnegie Mellon University (CMU) in 2015.

OUR TEAM

I work closely with Dr. Juanru Li from Shanghai Jiao Tong University. Moreover, I collaborate with the excellent researchers from different universities and research centres.
