The Department of Computer Science and Engineering at Yonsei University's Graduate School was established in 1988 within the College of Science to cultivate professional talent in the field of computer science. Reflecting the diverse demands of applied sciences and engineering, it moved to the College of Engineering in 1996. To lead AI-centered paradigms, such as the Fourth Industrial Revolution, and to strengthen interdisciplinary research and education within and outside the university, the department was reorganized under the College of Computing in 2022. For over 40 years, the department has produced outstanding talents and conducted world-class core and interdisciplinary research in computer science. Currently, the department comprises approximately 200 graduate students (both master's and doctoral programs) and 24 faculty members.
The core of computer science education at Yonsei is to nurture global leaders in information and AI-driven societies who can contribute to national and human development. The education emphasizes fostering creative thinking, the ability to understand and solve real-world problems, and the development of practical skills in the computer science field.

Research in computer science covers fundamental areas such as data structures, algorithm analysis, and theoretical computer science, which form the foundation for problem-solving through software. In computer systems, active research is conducted on computer architecture, including cutting-edge GPU and many-core architectures, high-performance computing, and distributed systems. Core fields also include operating systems, system software, compilers, and programming languages.
Rapid growth is seen in areas that connect platforms and communications, such as computer networks, the Internet, 5G/6G mobile communications, and the Internet of Things (IoT). Additionally, blockchain and cybersecurity technologies have emerged as essential research areas for ensuring secure communications in systems and network environments.
Data-centric fields like databases, big data analytics, and data and text mining also form a major pillar of computer science.
Leading the Fourth Industrial Revolution, technologies like Artificial Intelligence (AI), machine learning, deep learning, multimodal AI, and natural language processing (NLP) are now at the core of modern computer science. Alongside these, emerging paradigms such as virtual reality (VR), augmented reality (AR), computer graphics, multimedia processing, human-computer interaction (HCI), brain computing, and quantum computing are becoming key future research areas.

Computer science plays a central role in driving the future society's information, data, and AI industries. The demand for software and AI specialists, as well as for computer science technologies across various fields and the broader cyber space, is growing rapidly.
For instance, key algorithms and machine learning technologies are critical in autonomous vehicles; perception and mobility technologies are vital in the robotics industry; and software and AI technologies are essential across diverse areas of the healthcare industry.
Graduates from the Department of Computer Science pursue diverse career paths, including university professors, researchers at computer and software-related institutes and companies, and R&D personnel at leading global corporations such as Samsung Electronics, Hyundai Motor Company, Google, Apple, and Meta. They are also active in consulting firms specializing in management and systems applications.
Moreover, graduates have founded startups such as Daum Communications, VirtualTek, SOCAR, and Vibe, and are contributing to theoretical development and practical applications in cutting-edge fields like autonomous systems, quantum computing, and robotics.
Additionally, some graduates have entered public service (through technical civil service exams) or have become patent attorneys, making key contributions to technological innovation and intellectual property protection in the rapidly evolving digital landscape.

Yonsei University's Graduate School Department of Computer Science and Engineering participates in the BK21 (Computer Science and Engineering BK21 Graduate Program for Core SW Researchers and Problem Identifiers) program, aiming to emerge as a global top-tier research group in AI-based future computing for the Fourth Industrial Revolution era.
Through this initiative, the department has established strategies for nurturing talent, promoting research that responds to future societal changes, strengthening industry-academia cooperation focused on solving social issues, and building a world-class global research network.
