I am an Assistant Professor at the Informatics Department (DI) of the Faculty of Sciences, University of Lisboa (FCUL) and a researcher at the Human-Computer Interaction and Multimedia (HCIM) Research Team at LaSIGE, a research unit of the same department, where I keep striving to empower disabled people and help surpassing the barriers of accessibility, particularly in mobile contexts. I am active on FCUL Labs, which I co-founded, a cross-disciplinary group that seeks to develop and deploy products closer to the community. I received my PhD in Information Systems & Computer Engineering from Instituto Superior Técnico (IST), Technical University of Lisbon (UTL). Currently, my main research interests are on mobile accessibility for blind and motor impaired people, cognitive and communication aids for people with dementia, usable security and inconspicuous interaction.
