Research Interest: study human social dynamics on the web via an interdisciplinary approach of Computer and Social Sciences. I model user and group behavior (e.g., intent, attitude, belief and engagement) in online communities to help design cooperative information systems between citizens and organizations. This research is employed into a variety of humanitarian informatics problems for social impact, including crisis response, gender-based violence, public health resilience, and education assessment.
Technical Interest: merge top-down and bottom-up data mining approaches by employing domain semantics and guidance from offline socio-behavioral knowledge into statistical methods, and understand online user-group behavior from unstructured, large-scale social and web data.
