About the iSensor Research Team
Dr. Shuyuan Mary Ho Metcalfe, Ph.D. is interested in trusted human-computer interactions research, specifically addressing issues of cyber insider threats and automated detection of online deception in spontaneous communication. Dr. Metcalfe founded the iSensor Lab in 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 was funded by U.S. Air Force STTR grant (Phase I AF21A-TCSO1-0185, FA864921P139 and Phase II AF21A-TCSO1-15465, FA864922P0708, 05/01/20 – 06/28/23), National Science Foundation (NSF) Secure and Trustworthy Cyberspace EAGER grant (1347113/1347120 $199,998 09/01/13 – 08/31/15) and NSF I-CORPS grant (1505195 $50,000 12/15/14-12/31/16).
