summary: assistant professor at cnrs and insa lyon; ex-postdoctoral researcher at aalto university, helsinki,finland; phd at university of toronto; dipl.eng. at national technical university of athens; research on urban computing, polarisation on the web, social media; toolbox: python, scipy, networkx, scikit-learn, jupyter notebook, mongodb

This fall I join CNRS and INSA Lyon, France, as Assistant Professor (Maitre de Conférences).

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.

My interests lie mostly in the analysis of user-generated content on online social networks, social media, and other web platforms. For the current academic year, in particular, my research focuses on urban computing and polarization on the web. My hope is that, through the analysis of our online activity, we’ll be able to discover social patterns of behavior, understand their effects, and ultimately develop the tools for a better – and more social – Web. More on my work.

Finally, I am a co-founder of Helvia, a data analytics and applications company.
