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). I also work closely with industrial research labs on cutting-edge problems, typically as a visiting researcher. The most recent engagements included Spotify (2018), Amazon (2019), and Microsoft Research AI (2020).

My research revolves around intelligent systems. On one hand, I am trying to make search and recommendation systems smart, proactive, and integrated. On the other hand, I am investigating how such systems can be made fair, transparent, and ethical. The former area is Search/Recommendation and the latter falls under Responsible AI. They both create interesting synergy, resulting in Human-Centered ML/AI.

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 search and recommendation, social media, and fairness in ML. 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. If you are interested in working with me, please check out these research groups/labs before contacting me.
