My core research interest is in the area of Social Computing where I examine how users, communities, and networks evolve on social media. I am also interested in data-driven approaches towards informing digital rights and accountability. In particular, my research examines the following topics:

• Churn prediction (from online services, applications, and communities) using machine learning techniques.
• Recommender systems with collaborative filtering - with an emphasis on latent-factor models.
• Information diffusion models (e.g. general threshold, multivariate cascades).
• Large-scale data mining using parallel-processing techniques implemented over distributed hardware.
