Debin Liu is a PhD candidate at
School of Informatics and Computing, Indiana University, Bloomington, Indiana since Fall 2005 with major in
Security Informatics and minor in Finance and HCI.
His study focuses on Usable Security and Fraud Prevention. His PhD dissertation title is "Incentive, Behavior and Information Security Management", advised by Dr. L. Jean Camp.
He is actively seeking a full-time position to apply his research and analytical skills in Information Security to help secure systems and applications: reviewing actual and perceived security vulnerabilities, identifying consumer experience trouble spots, analyzing and detecting online frauds, assessing risk and outlining remediation strategies.
His latest CV in PDF format can be found here.
