Research Interest: study human behavior on the web via an interdisciplinary approach of Computer and Social Sciences. I model individual and group behavior (e.g., intent, attitude, belief and engagement) in online communities to design cooperative information systems that mine crowd-generated and opensource data to support organizational decision making. This research is employed into a variety of humanitarian informatics problems for social good, including emergency management, 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 individual and group behavior from unstructured, large-scale social and web data.

Studying real-world problems
related to online human social dynamics (engagement, intent, belief, cooperation) in social network communities by leveraging models using behavioral knowledge from psychology (Social Identity, Social Cohesion, etc.). I have worked on Intent Mining, Bipartite Matching, Expert Detection, Community Evolution, and User Engagement analysis in large-scale unstructured data from social media. My research has key applications in improving humanitarian crisis coordination and the understanding of online user behavior.
