Curriculum Vitae

João Pedro Vieira Guerreiro

João Guerreiro is an Assistant Professor at Faculdade de Ciências da Universidade de Lisboa and an integrated researcher at LASIGE. Previously, he was a Postdoctoral Researcher and a Project Scientist at Carnegie Mellon University. He received his PhD with distinction and honour in Information Systems and Computer Engineering from Instituto Superior Técnico, Universidade de Lisboa. His primary research, in the fields of Human-Computer Interaction and Accessible Computing, aims to improve visually impaired people's access to the physical and digital world using novel non-visual interaction techniques and systems. His most recent research has focused on inclusive virtual environments, with a particular interest in using Virtual Reality in accessibility and healthcare contexts. His past research efforts have resulted in the deployment of novel prototypes in the real world, advancing the state-of-the-art and impacting the lives of people with disabilities. Examples of such deployments include the installation of a navigation system (NavCog) at Carnegie Mellon University, Pittsburgh International Airport, Allegheny General Hospital, and DoubleTree Hotel in Pittsburgh during a conference for the Pennsylvania Council for the Blind. João Guerreiro has published more than 50 peer-reviewed scientific papers, of which 25+ are published in venues currently classified as CORE A* or A (conferences) and Q1 (journals). João was awarded the 2020 Best Junior (Early Career) Researcher at the LASIGE research unit. He has also been awarded five best paper distinctions (CHI'14 and CHI'23, ITS'15, W4A'19, and ISS'20), a Google Student Award, and an Accessibility Challenge Delegates Award (Best Demonstration at W4A'19). He has served as General Chair of the International Conference on Mobile and Ubiquitous Multimedia (2022) and in the organizing or program committee of the most relevant conferences in his research field, such as ACM CHI and ACM ASSETS. João Guerreiro is the PI of an ongoing FCT PTDC 2022 PEx project on Accessible virtual environments (AccessVR) and has participated in eleven scientific projects where his research team had an overall budget of approximately 3 million euros, including European projects, projects funded by the (United States) National Science Foundation or by the (Portuguese) Fundação para a Ciência e Tecnologia, and projects funded by industry (e.g., Shimizu Corporation).. These projects intersect with various disciplines relevant to Human-Computer Interaction and Accessible Computing in particular, and computer science at large, such as Collaborative and Virtual Environments, Multi-Agent Systems, Indoor Navigation, Rehabilitation, Human-Robot Interaction, Computer Vision, Information Visualization, and Cognitive Sciences. João has successfully advised 9 MSc students (+4 co-advised) and is currently advising 5 MSc students (+3 co-advising). He advises 3 PhD students.
