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. |
