I am interested in algorithms and interfaces for improved information retrieval, as foundations of semantic web technologies pdf download as general issues in human-computer interaction. I have been at Microsoft Research since July 1997. My current research focuses on gaze-enhanced interaction, the temporal dynamics of information systems, user modeling and personalization, novel interfaces for interactive retrieval, and search evaluation.
Prior to coming to Microsoft, I co-developed a statistical method for concept-based retrieval known as Latent Semantic Indexing. Colloquia: Drawing causal inference from big data.
