I am an Assistant Professor at the Technology, Policy, and Management (TPM) faculty at TU Delft. I am also an Associated Researcher with the Max Planck Institute for Informatics (MPI-INF) and a core member of the International Data-driven Research for Advanced Modeling and Analysis Lab (iDrama Lab).

Research

Overall, my research focuses on applying machine learning and data-driven quantitative analysis to understand emerging phenomena on the Web such as the spread of false information and hateful rhetoric. I am also interested in understanding algorithmic recommendations on social media platforms. My research has been published at top-tier conferences such as WWW, ICWSM, and ACM IMC. My co-authors and I have received best/distinguished paper awards at ACM IMC 2018, best paper honorable mention awards at ICWSM 2020 and CSCW 2021, as well as a best paper award at CyberSafety 2019.

Personal

I was born in Larnaca, Cyprus. I spent most of my life in Cyprus, however, during my studies, I travelled to several locations in Europe and the USA. In my free time I try to get out of SilverGold division in League of Legends (mainly playing at the top lane with Jax), I like to watch various sports including Football (or soccer as my American friends call it), Basketball, and Tennis. Also, I regularly shitpost online, with my colleagues, and generate some high quality memes for fun/trolling. Furthermore, I lurk various Web communities including 4chan’s /pol/.
