Recruitment

CEED Lab focuses on research in knowledge graphs, AI and digital education, AI ethics, and inclusive digital education for diverse learners, including seniors. Our research aims to create an educational environment where everyone can understand and effectively use AI and digital technologies by integrating computing technologies with education. In particular, we explore a wide range of topics, including knowledge representation and utilization based on knowledge graphs, AI-supported teaching and learning methods, ethical and social issues surrounding responsible AI use, and digital education approaches designed for diverse learners across different age groups.

Students who join the lab will participate in various research projects under the supervision of Prof. Sujin Yoo. Through these projects, students will gain hands-on research experience connecting computing and education, such as data analysis, knowledge graph construction and applications, and the development of AI-based educational content. During the research process, students will also experience essential stages of research, including problem definition, data collection and analysis, system design and implementation, and the organization and presentation of research outcomes.

Through these experiences, students will develop interdisciplinary research skills that bridge computer science and education, while also building the problem-solving abilities and research experience required in the future digital society.
