I'm an Associate Professor in Information School, an Adjunct Associate Professor in Paul G. Allen School of Computer Science & Engineering, and an Adjunct Associate Professor in Human Centered Design & Engineering (HCDE) at University of Washington (UW). In 2018, I was a Visiting Research Scientist at Spotify and in 2019, an Amazon Scholar. Prior to UW, I was an Associate Professor at Rutgers University. Currently I am also a Visiting Researcher with Microsoft AI.

My research interests include studies of interactive information retrieval/seeking, trying to understand the task a person is doing and providing proactive recommendations. I also study social media and data generated by wearable devices as kinds of signals that can help us understand and impact human behaviors. I apply them to various problems related to search, personalization, and recommendation. Recently I have also been exploring ways to reduce bias and bring fairness in search and in general in Machine Learning. My work -- Human-Centered ML/AI -- falls under and uniquely connects Computer Science, Data Science, and Information Science.

I received my PhD in Information Science from University of North Carolina (UNC) at Chapel Hill. I hold an MTech, Computer Science & Engineering from Indian Institute of Technology (IIT) Madras, India and an MS, Computer Science from University of Massachusetts (UMass) Amherst. I have published and talked extensively on topics related to social and collaborative information seeking, interactive information retrieval, and social media. I have served as a consultant to the United Nations Data Analytics on various Data Science projects involving social and political issues, peacekeeping, climate change, and energy.

At UW, I direct the InfoSeeking Lab, as well as special interest groups on Neural IR, Social Information Seeking, and Sensor-Aware Information Seeking Behavior.
