About

Dr Nicholas Micallef is a Lecturer at Swansea University. His research interests include HCI, Misinformation, Usable Security and Privacy, Authentication and Mobile HCI. His recent research focuses on misinformation both from a data-driven and human aspects perspective. In his previous role at New York University Abu Dhabi he was involved in various projects that studied the countering of misinformation and the spreading of cross-platform multimodal misinformation. In his position at the University of New South Wales his research focused on designing privacy-enhancing technologies that provide users with realistic information to anonymize their online identities. Dr. Micallef obtained his PhD from Glasgow Caledonian University United Kingdom. In his PhD he investigated the use of mobile sensing to improve the usability of smartphone authentication

Taught Modules

CS-130 Professional Issues 1: Computers and Society

Students will be introduced to the main professional issues associated with software engineering and computer science research. Students will also examine the main impacts of computing on society and social issues on the practice of computing, including legal and ethical concerns such as copyright and the Data Protection Act 2018 (i.e., the UK¿s implementation of the General Data Protection Regulation - GDPR). Issues of network security will also be discussed. The course also includes communication and technical-report writing skills.
