Research Interests

V.S. Subrahmanian focuses on the intersection of AI and security problems. He develops machine learning based models to analyze text/geospatial/relational/social network data, learn behavioral models from the data, forecast actions, and influence outcomes. His models have been used to forecast terror attacks and terror network evolution, to reduce poaching, to identify bad actors on social media, to forecast systemic banking crises, to maximize airline profits, to predict if apps are malware or not, and more.
