Ruba Abu-Salma is a Ph.D. student in the Department of Computer Science at University College London (UCL) in the UK, supervised by Prof. M. Angela Sasse and Dr. Sarah Meiklejohn. All three are members of the Information Security Research Group. Ruba’s research focuses on taking a user-centered approach to the design and use of secure communications. Ruba is currently supported by a SUDS (Supporting Usability and Design in Security) Fellowship from the Open Technology Fund. During her fellowship, Ruba will work towards creating foundational knowledge for the design of communication tools that support secure group chat in line with users’ needs, mental models, perceptions and computer security practices.
