I am an Assistant Professor in the Computer Science and Engineering Department at the University of South Florida. My research focuses on behavioral biometric authentication and applications of ubiquitous sensing. I lead the Cyber Identity and Behavior Research Lab (CIBeR). My group uses applied machine learning and mixed method research design for exploring applications of low-cost sensors for cyber security, biometric recognition, and healthcare applications. Research related to cyber security includes continuous authentication for IoT systems, with a particular emphasis on mobile sensors. Many efforts are collaborative, involving enhancement of mental health services by inferring emotional and social contexts from mobile sensors and measuring physical phenomena such as synchronization within human dyads.
