About the iSensor Research Team
Dr. Shuyuan Mary Ho Metcalfe, Ph.D. actively conducts trusted human-computer interactions research, addressing issues of cyber insider threats, computer-mediated deception and deepfakes. Dr. Metcalfe directs a team of researchers at iSensor Analysts Lab since 2010. iSensor Lab is primarily dedicated to sociotechnical research related to human factors (e.g., behavioral threat) in cyberspace. Experiments are conducted in a live, and virtual laboratory. Dr. Metcalfe’s sociotechnical research approach utilizes social-psychological theories along with pragmatic viewpoints on language-action cues to create an innovative methodology for computational modeling of next generation predictive behavioral reasoning systems—analyzing complex trust relationships, human disposition and intent detection. Dr. Metcalfe has been funded by U.S. Air Force, National Science Foundation, and Florida Center for Cybersecurity. Her research can be found in Journal of the American Society for Information Science and Technology, Journal of Management Information Systems, Computers in Human Behavior, Computers & Security, Computational and Mathematical Organization Theory, Information Systems Frontiers, Information Processing & Management, AIS, ASIS&T, ACM, IEEE, Springer, and many world’s leading refereed publications.
