Explore the principles of computation and intelligence to create the future.

In the Department of Information Science, students engage in a vast spectrum of study and research, ranging from the theoretical foundations of computation to programming languages, graphics, computer vision, computer architecture, machine learning, and bioinformatics.

By delving into the principles and theoretical underpinnings of information processing, students acquire exceptional technical proficiency—an ability to create something out of nothing. This emphasis on fundamental knowledge fosters intellectual resilience, a quality that will undoubtedly serve them well, no matter which field they pursue in the future.

Understanding the Foundations of Computing and Cultivating the Ability to Create from Scratch

A common question concerns the distinction between this department and those in engineering faculties that focus on information-related fields. The fundamental difference lies in our approach: here, we study information itself—its theories, systems, and applications—through a comprehensive and systematic curriculum covering everything from the theoretical foundations of computing to its practical implementation.

For instance, students in this department undertake experiments in which they design and implement everything from a computer’s CPU and hardware to compilers and applications. This hands-on experience of constructing a computer from scratch is an invaluable and distinctive aspect of our program, unparalleled in other departments. While engineering faculties tend to emphasize practical applications, the Faculty of Science’s Department of Information Science places greater importance on principles and theories.

As a center for cutting-edge research in computing, the department ensures that undergraduates first develop a deep understanding of computational principles and theoretical backgrounds. The curriculum fosters the ability to abstract complex problems and the technical skill to create new systems from scratch. Though mastering these foundational elements may seem like a long and indirect path, the intellectual strength gained through this rigorous training will prove indispensable, no matter where students choose to apply their expertise after graduation.
