SMU Assistant Professor of Information Systems Kim Youngsoo, an empirical economist by training, is intrigued by how our behaviour, including the way we communicate and make decisions, is changing because of smartphones and social media. Similar to how historians record notable events for posterity, Associate Prof Kim wants to curate this IT-based evolution and analyse the socio-economic changes that are taking place along with it. In particular, he is interested in how IT products such as social media, e-commerce and Global Positioning System (GPS) are changing user behaviour.
