Dr. Haewoon Kwak is an Associate professor at the Luddy School of Informatics, Computing, and Engineering, Indiana University Bloomington. He and Prof. An co-run a research group, Soda Lab, with focus on studying social phenomena through large-scale data and computational tools, aiming to tackle big societal problems.
Dr. KWAK's research lies in the intersection of network science, machine learning, and computational social science across diverse domains, such as news media, online games, social media, sports, politics, and so on. He is a lead author of “What is Twitter, a social network or news media?” (WWW 2010), which has been cited more than 9,000+ times. His work has been featured by Nature News, ACM Tech News, BBC, The Times, The Economist, Slate, Scientific American, and many others. He has been a member of SPC/PCs of major CS and computational social science conferences.

Online social networks and social media

How are they changing people's lives?

Structures and dynamics of every system, from an online social networking service to a football team, interact with each other. Retweets in Twitter go along with follow relationship and those lead to an act of following to the original author. Similarly, positions of football players and passes between them are strongly related. Network science is an interdisciplinary research field to examine underlying structures, dynamics therein, and relationship between two.

Game analytics

A miniature of the real world

Online game players interact with each other in various ways, as they do in the real world. More importantly, in-game actions could be easily quantified and logged in detail. The huge volume of behavioral data collected in online games help researchers study human nature in an unprecedented scale.

Computational journalism

Is the world flat? -- We are finding answers from global news media

We are strongly relying on domestic news media to obtain information on foreign countries even in the era of social media. Which countries are more frequently reported than others? Which countries are more positively reported than others? Such patterns unconsciously shape our worldview. With large-scale databases from online news sites, what events are chosen and how they are reported can be quantitatively measured.
