During my PhD journey, I investigated users' awareness of the privacy and security implications of smart homes [1]. My research expanded to devising strategies to increase awareness [2], enable control [3], and design usable authentication mechanisms [4,5] in this specific context. Beyond that, I engaged in diverse side projects, including interactive museum exhibits [6, 7], exploring user perceptions of physiological sensing technologies [8], and biometric authentication [9, 10].
