Database, Data Mining and Big Data

Jeremy Blackburn researches a better understanding of how people behave online. He is particularly interested in “bad” behavior and has studied how cheating spreads like a disease in a social network of gamers, mis- and disinformation, online extremism and memes. As part of this broader work, he is building practical tools and systems for large-scale data collection and analysis with the https://iDRAMA.cloud project.
