The Usable Security Empirical Research Lab

Welcome to the home page for the Usable Security Empirical Research (USER) lab at the University of Tennessee, Knoxville (UTK). The USER lab sits at the intersection of cybersecurity, privacy, and usability research. We measure and evaluate the effectiveness of existing security solutions, explore mental models and perceptions related to cybersecurity and privacy, and build novel security technologies to improve the lives of users the world around. In contrast to most security research labs, our research group integrates HCI methods to ensure that we properly understand the needs of users and that the technologies we build meet real-world needs and are used correctly. Our research group’s work has been published at top cybersecurity (IEEE S&P, USENIX Security, ACM CCS) and top HCI (CHI, UIST, UbiComp) venues.
