Understanding how big data and AI reshape exploration, creativity, and innovation.
Yulin Yu is an incoming Assistant Professor at the University of Arizona, College of Information Science, where she is the Principal Investigator and Director of the AHA Lab (Analytics of Human & Artificial Intelligence). She is a computational social scientist studying human–AI interaction and innovation, with a focus on how disruptive technologies impact people and society. Her current research examines how big data and AI transform the ways people explore, think, and innovate across science, art, and the technology workplace (PNAS 2024, CHI 2026). As a human-centered data scientist, she analyzes large-scale digital trace data by developing and applying computational and statistical frameworks.
Her research has been published in top-tier general science venues (e.g., PNAS) and leading computational social science/HCI venues (e.g., The Web Conference, ICWSM, CSCW, and CHI). She was recognized as an EECS Rising Star by MIT and has received a Special Recognition Award from IC2S2. Beyond academia, her research has attracted attention from prominent science communication outlets, including Science, ScienceDaily, and Inside Higher Ed. She received her Ph.D. from the University of Michigan School of Information and has been affiliated with Microsoft Research, the Northwestern University Kellogg School of Management, and the Northwestern Institute on Complex Systems (NICO).

Research Lab and Perspective Student
The AHA Lab — Analytics of Human & Artificial Intelligence — studies how human and artificial intelligence systems shape exploration, knowledge production, creative work, and innovation. Methodologically, our lab uses a range of computational social science approaches, primarily leveraging large-scale digital trace data. We apply natural language processing, network science, and statistical modeling to design social measurements and extract patterns and insights.
I am actively looking for motivated pre-PhD students, research assistants, visiting students, and prospective PhD applicants interested in human–AI interaction, computational social science, science of science, creativity, and innovation. Prospective PhD applicants for the 2027 cycle are welcome to reach out in advance.
- Human–AI interaction and information diversity
- Big data, scientific discovery, and innovation
- Creativity and computational measures of novelty
Personal
Art motivates creativity in research. I am a classically trained mezzo-soprano; you can visit my performances on YouTube. I am also interested in visual art; for earlier creative projects, visit my undergraduate arts page.
I am also a big fan of outdoor activities, including hiking, scuba diving, and visiting national parks.
