About me

I am a faculty member at the department of computer science at the university of Toronto. I conduct research in the areas of data management, analysis of big data, data science and applied machine learning. My main interest is to develop techniques and build systems capable to analyze and process massive and diverse data sets. My current focus is in the intersection of recent machine learning techniques and data management.

I received a Bachelors Degree from the University of Patras in Greece, a MSc from the University of Maryland at College Park and a PhD degree from the University of Toronto.

I co-founded Sysomos a social media monitoring and analytics company, commercializing the research project BlogScope.

I have received two best papers awards for my research and served as the research DB track chair for CIKM 2010, as research program co-chair for VLDB 2011, as the Industrial program chair for SIGMOD 2013, as the sponsorship chair for SIGMOD 2014 and 2015 and the tutorial co-chair for VLDB 2018. I also serve as an associate editor for VLDB 2019. I served as a member of the G7 at the Creative Destruction Lab at the Rotman School of Business. I was named the 2011 inventor of the year by the University of Toronto (1st prize) and I serve as an advisor at Round 13 Capital and Highline in Toronto. I am also a co-founder at the Social WiFi Marketing and Analytics company Aislelabs
