I am a Postdoctoral Researcher in Web Data Driven Hybrid Human-Machine Systems within the Web Information Systems group at Delft University of Technology (TU Delft). I am also a Visiting Researcher of the Vrij Universiteit of Amsterdam, where I join the User Centred Data Science (UCDS) group group lead by Professor Lora Aroyo.

Education and Previous work

I graduated from the Electrical and Computer Engineering School of the National Technical University of Athens on 2013 (ECE National Technical University of Athens). After that, I also received a Research Master with double affiliation from IMT Atlantique (formerly known as Telecom Bretagne of Brest, France) and the University of Rennes 1 in Human Centered Computer Science.

During my PhD i worked for DRUID team (IRISA institute) under the Supervision of Professor David Gross Amblard and Assistant Professor Zoltan Miklos. I obtained my PhD in November 2017 focusing on quality improvement for task assignment methods in human computation. There I developed and tested a user and task model based on a scalable (for current Crowdsourcing platforms such as Amazon Mechanical Turk and FigureEight) hierarchical skill model that gives a significant improvement in quality when used for task assignment. My research was mainly funded by a MESR funding of the French Ministry of Education and part of my research was also funded by the ANR HEADWORK project.


My commitment and dedication to research has been rewarded with a PhD grant from the French Ministry of Education and latter on I had the honour to receive the best student paper award for my paper that I presented in WWW2016 in Montreal, Canada.
