I am faculty member (Maitre de Conférences) at CNRS and INSA Lyon, France. Before that, I spent four years as a postdoctoral researcher at Aalto’s Data Mining Group, where I worked with Prof. Aris Gionis. Before I came to Helsinki, I received a PhD in Computer Science from the University of Toronto, where I worked with Prof. Nick Koudas, and a Diploma of Engineering from the National Technical University of Athens.
