Haijun Xia

Haijun Xia is an Assistant Professor at the University of California, San Diego (UCSD), where he directs the Foundation Interface Lab and contributes to the Cognitive Science and Design Lab. His work focuses on Human-Computer Interaction (HCI) and Human-AI Collaboration, emphasizing the development of dynamic, malleable interfaces that integrate human cognition with intelligent systems to enhance thinking and working paradigms.

• Education:
  • Bachelor's, Tsinghua University
  • Master's and PhD, University of Toronto

His research spans generative AI, interface design, and creative collaboration, with applications in data visualization, programming, and scholarly work. He advocates for treating information as a malleable material that can be flexibly manipulated by users and AI agents.

Recent publications highlight advancements in:

• 2025 CHI Conference - Generative user interfaces, malleable overview-detail designs, and compositional structures for human-AI co-creation
• 2024 CHI Conference - Structured design space exploration with LLMs, ASCII diagram analysis, and adaptive presentation systems
• 2023 CHI/UIST Conferences - Data particle visualization, contextual logging tools, and metaphor generation for science communication

Scientific recognitions include:

• Multiple Best Paper Awards and Honorable Mentions at CHI and UIST
• Hellman Fellowship and grants from NSF, Microsoft, Google, Meta, Apple, and Adobe

He actively recruits undergraduate and graduate interns and has an upcoming postdoc position in early 2025 for researchers interested in foundational interface development.
