  • Accepting PhD students

Rizka is currently an Assistant Professor to the Master of Cybersecurity with Monash University, Indonesia and Adjunct Associate Lecturer at University of New South Wales. Prior to this role, she was a postdoctoral researcher at UNSW Canberra Space, with past experiences working as a software engineer in Australia and Indonesia.

Her research interests are mainly in the application of artificial intelligence in various areas. Her current research interests include scams and phishing attacks, specifically on improving cybersecurity awareness, and developing AI based methods that could automatically help detect phishing attacks and scams. Besides AI for cybersecurity, she is also currently working in the area of AI for space, particularly on the use of federated learning on miniaturised satellite constellations, and space object characterisation using lightcurve data with deep learning.

Rizka received the bachelor’s degree in electrical engineering from Institut Teknologi Bandung (ITB), Indonesia, in 2013, and the master’s degree from the University of New South Wales (UNSW) in 2018, concentrating on artificial intelligence and internetworking. She completed her PhD  in 2022, from the School of Computer Science and Engineering at UNSW. Her PhD was funded by the University International Postgraduate Award (UIPA) and Cyber Security Cooperative Research Centre scholarships.
