Zhichen Guo
PhD in Psychometrics
About Me
I am a PhD specializing in Psychological Measurement (Psychometrics) and currently a Postdoctoral Researcher at The Chinese University of Hong Kong, Shenzhen. My research lies at the intersection of artificial intelligence and psychological science, with a focus on AI-driven assessment, multimodal data integration, and advanced psychometric modeling. I am particularly interested in how large language models and other AI techniques can enhance personality assessment, intelligent testing, and psychological measurement more broadly.
On this site, you will find information about my ongoing projects, publications, and academic contributions. I am passionate about advancing knowledge in my field, fostering interdisciplinary collaboration, or addressing real-world challenges through research.
Research Interests
- Latent Variable Modeling (e.g., Item Response Theory, Cognitive Diagnostic Models)
- Multimodal Data-Driven Assessment
- Educational Data Analytics
