I study what happens when people and information systems, particularly recommender systems, collide in many different ways. This work blends human-computer interaction, artificial intelligence, and information retrieval to answer two key questions:
- How can we build information systems that are better able to meet human needs?
- How do these systems interact with people and society?
I am currently working on several problems around bias and discrimination in recommender systems, effective evaluation of recommender systems, and techniques to support specific information needs of various classes of users.
