At Yahoo he works with production teams of Flickr and Tumblr to build social recommender systems at scale. He has collaborated actively with several academic institutions worldwide. He organized the Social Informatics conference in Barcelona 2014.

Symeon Papadopoulos
Research Associate at CERTH-ITI
Thessaloniki, Greece

Bio: Symeon received a Computer and Electical Engineer degree from the Aristotle Univeristy of Thessaloniki in 2004, a Professional Doctorate in Engineering (P.D.Eng.) from the Technical University of Eindhoven in 2006, an MBA from Blekinge Institute of Technology in 2009, and defended his PhD thesis on social multimedia mining and knowledge discovery in the Informatics department of the Aristotle University in 2012. Since September 2006, he has been working as a research associate with the Information Technologies Institute (ITI), part of the Centre for Research and Technology Hellas (CERTH), on a wide range of research areas such as information search and retrieval, social network analysis, data mining and web multimedia knowledge discovery. He has co-organized a number of workshops in the area of social media mining (ICMR SoMuS 2014, WWW SNOW 2014, ICME WeMuV 2015), the Summer School on Social Media Modeling and Search (SSMS 2012), and the 10th European Summer School on Information Retrieval (ESSIR 2015).

Haewoon KwakHaewoon
Scientist at QCRI
Doha, Qatar

Bio: Haewoon is a data scientist with a background in complex networks, and has studied online social networks for many years. He has worked with social scientists, physicists, and scientists in other fields since 2007, and such experiences have guided his multi-disciplinary approach to finding and solving complex problems. He is a lead author of “What is Twitter, a social network or news media?” (WWW’10), which has been cited more than 2,000 times. Similar to his Twitter paper, he is always exploring new areas, such as his work on YouTube and other online social networks. At QCRI, Haewoon focuses on computational social science and computational journalism. He investigates human nature through large-scale electronic traces collected from popular user services, such as Twitter, Reddit, online games, etc. Haewoon also works on news media interplay with social media and society at-large.
