Yan Han is an Instructor and Full Library Faculty member at the University of Arizona's College of Information Science. His research focuses on Optical Characterization Recognition (OCR), Data Science, and Metadata (XMP), with active participation in ISO standards development (e.g., XMP metadata, PDF standards). He leads projects such as the Afghanistan Digital Repository (afghandata.org) and the Pashto-English Dictionary (pashtoenglish.org), and contributed to the U.S. Electronic Theses and Dissertations white paper. His work emphasizes recycling mine tailings, biopolymer-stabilized materials, and sustainable construction solutions.

Research interests include metadata standards, OCR applications, and data-driven library systems. He has advised over 12 students who secured roles in tech companies (Amazon, Microsoft) and academic institutions. His technical contributions span geopolymer composites, structural health monitoring, and rock mechanics. Awards and grants are not explicitly listed, but his extensive publications and ISO committee involvement highlight professional recognition.

Key collaborations include the ANSI Technical Advisory Group and ISO/TC171. His lab and team efforts focus on digital preservation, metadata interoperability, and environmental applications of geopolymer materials. Current work continues exploring smart materials for construction and library informatics.
