I'm an Associate Professor of Information Science and an affiliate member of Computer Science at Rutgers University. Currently I am also a Visiting Research Scientist at Spotify.

My research interests include studies of interactive information retrieval/seeking, especially those involving social and collaborative aspects. I 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. My work 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 serve 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 Rutgers, I direct the InfoSeeking Lab, as well as special interest groups on Collaborative Information Seeking, Social Information Seeking, NeuIR, and Sensor-Aware Information Seeking Behavior. I am also affiliated with Social Media and Society cluster, HCI Lab for Health & Sustainability (HCIL), and the Rutgers Climate Institute. If you are interested in working with me, please check out these research groups/labs before contacting me. Look at my research themes, currently funded projects, and a list of my current and past students.

I'm a competitive ballroom dancer and teacher, and an avid traveler. My wife Lori, our daughters Sophie, Zoe, Sarah, and I live in Somerset, NJ with our dog Legolas, guinea pig Wilbur, and a fish named Spot!
