Talks: Gustave Tuck Lecture Theatre, Main UCL Building

Coffee breaks and lunch: South Cloisters, Main UCL Building




Invited speaker: Yvonne Rogers

Session Chair: Mirco Musolesi

Title: On Being Challenged

Bio: Yvonne Rogers is a Professor of Interaction Design, the director of UCLIC and a deputy head of the Computer Science department at University College London. Her research interests are in the areas of interaction design, human-computer interaction and ubiquitous computing. A central theme of her work is concerned with designing interactive technologies that augment humans. She was awarded the ACM SIGCHI Lifetime Achievement Research Award in 2022, “presented to individuals for outstanding contributions to the study of human-computer interaction.” In the same year, she was elected as a fellow of the Royal Society as “one of the leaders who created the field of Ubiquitous Computing”.

Bozidar received his PhD in technical sciences from EPFL.


Reception (in Haldane Room, Main UCL Building)

Tuesday 5th July

Talks: Gustave Tuck Lecture Theatre, Main UCL Building

Coffee breaks and lunch: North Cloisters, Main UCL Building


Invited Speaker: Kate Farrahi

Session Chair: Nic Lane

Title: Machine learning for mobile health and digital epidemics

Bio: Kate Farrahi is an assistant professor at the University of Southampton working in the vision, learning and control (VLC) group. The focus of her research is on machine learning, particularly deep learning often applied to health-related applications. She is interested in developing machine learning techniques to address novel sensor-driven healthcare problems, including natural language processing and vision related applications such as medical imaging and contactless vitals measurements. She obtained her PhD in Computer Science from the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland.

Invited speaker: Hugo Spiers

Session Chair: Cecilia Mascolo

Title: Using a mobile app to study world-wide cognition

Bio: Hugo Spiers is Professor of Cognitive Neuroscience in the Department of Experimental Psychology and a Fellow of the Royal Institute of Navigation. His research explores how our brain constructs representations of the world and uses them to recall the past, navigate the present and imagine the future. Current research from his group use a range of methods including mass online testing with mobile apps, brain imaging, neuropsychological testing, virtual reality and single cell recording to understand brain function and spatial cognition.
