Biography
Chirag Shah is Professor in Information School (iSchool) at University of Washington (UW) in Seattle. He is also Adjunct Professor with Paul G. Allen School of Computer Science & Engineering as well as Human Centered Design & Engineering (HCDE). He is the Founding Director for InfoSeeking Lab and Founding Co-Director of Center for Responsibility in AI Systems & Experiences (RAISE). He works in the area of intelligent information access systems, focusing on task-oriented search, proactive recommendations, and conversational systems. He is also engaged in work with generative AI, specifically in information access and image classification problems. In addition to creating AI-driven information access systems that provide more personalized reactive and proactive recommendations, he is also focusing on making such systems transparent, fair, and free of biases.
Shah is a Distinguished Member of Association of Computing Machinery (ACM) as well as Association for Information Science & Technology (ASIS&T). He is the recipient of 2019 Microsoft BCS/IRSG Karen Spärck Jones Award. He has published nearly 200 peer-reviewed articles and authored seven books, including text books on data science and machine learning.
He is very selectively looking for new students in his lab and center with strong background and interest in generative AI, large language models in search and recommendation, and bias and fairness in information access systems.
