I am an Assistant Professor at Utrecht University. My research focuses on crowd systems, their potential and their applications. I develop methods that help people collaborate, coordinate their efforts and innovate at-scale and efficiently, online or within physical spaces. To do so, I apply an interdisciplinary approach, which combines computational science (machine learning, agent-based modelling, mathematical optimization) with social sciences (personality testing, team building).
Prior to joining UU I worked as a Senior Researcher at the Luxembourg Institute of Science and Technology (LIST), where I coordinated the European H2020 project CROSSCULT. In the past I have also collaborated with the Human-Computer Interaction Institute of Carnegie Mellon University as a visiting researcher, and with INRIA Nancy-Grand Est and the Public Research Center Henri Tudor as a postdoctoral fellow. I hold a Ph.D. and an Electrical and Computer Engineering degree from the National Technical University of Athens. I am part of the ERCIM and Marie-Curie alumni networks. |

Our paper exploring "Quality of Experience in Cyber-Physical Social Systems Based on Reinforcement Learning and Game Theory" is now published as open access in the Future Internet journal! Learn how game theory and machine learning can improve the quality of experience of people in a complex cyber-physical setting, like that of a museum.
Participated as discussant in the Fair of European Innovators in Cultural Heritage, an key event of the 2018 European Year of Cultural Heritage. Let's use Information Technologies to keep European Heritage Alive!

Our paper titled "When Crowds Give You Lemons: Filtering Innovative Ideas using a Diverse-Bag-of-Lemons Strategy" has been accepted at CSCW 2018. Read how involving crowds can help not only produce novel ideas but also effectively filter them. And of course, congratulations to our truly global (EU, US, China) co-author team that made this work possible.
