Biography

Zahra Ghafoori is a postdoctoral research fellow in the University of Melbourne Academic Centre For Cyber Security Excellence. She studied her PhD at the School of Computing and Information Systems, University of Melbourne, where she developed robust and efficient techniques for unsupervised anomaly detection in complex and dynamic environments. Prior to her PhD studies, she worked as a security expert in Informatics Services Corporation, a top-tier IT service provider for Core/Retail Banking Solutions. She has hands-on experience in cybersecurity risk assessment, incident management, and security auditing. 

Zahra Ghafoori is interested in designing algorithms that with limited or no feedback on their performance can learn patterns from massive data collections and are robust against adversarial examples.
