My research interests include multifacets of Information Retrieval (IR) systems that are situated in a social context. My recent studies focus on bringing fairness and transparency to IR. In particular, I try to understand the bias associated with search and recommendation systems. I develop fundamental frameworks and efficient algorithms to strike a balance between fairness and different factors of IR systems.
