I am a Senior Researcher at Microsoft Research, Redmond, USA.
My research interests lie at the intersection of information retrieval, data mining, and human-computer interaction. I study how people search for information in domains such as the Web and the enterprise, and develop tools to help people search more effectively, solve problems, and learn. My three current foci are search interaction, expertise modeling, and health seeking.
I chair the steering committee for the ACM SIGIR Conference on Human Information Interaction and Retrieval (CHIIR), pronounced "cheer". CHIIR is a merger of HCIR and IIiX. CHIIR 2016 will be in March 2016 in Chapel Hill, NC.
Our book entitled "Exploratory Search: Beyond the Query-Response Paradigm" was published
