In this blog post, we’ll examine the development of the electrical and electronics industry—one of South Korea’s core industries—as well as the education and research programs at Seoul National University’s School of Electrical and Information Engineering, and explore the opportunities that electrical and information engineering offers across various industries and career paths.

Electrical and Electronic Technologies Driving South Korea’s Key Industries

In 2006, during my senior year of high school, I spent about a month in the UK for a training program over the summer break. I remember being quite surprised when I browsed the home appliance section at Harrods—one of the UK’s largest luxury department stores at the time—and saw that products from Samsung Electronics and LG Electronics dominated the floor. Products from companies like Sony and Panasonic—which had been regarded as symbols of aspiration just a decade or so earlier—were tucked away in a corner, barely noticeable, and even looked somewhat shabby by comparison. It was also impressive to see so many foreigners naturally accepting TVs and various home appliances made by Samsung Electronics and LG Electronics as products of world-class quality. At the time, the electrical and electronics industry accounted for a very high proportion of South Korea’s exports, and various indicators were emerging that demonstrated the industry’s role as one of the key growth engines of the South Korean economy. Since then, as related industries—including semiconductors, displays, information and communications technology (ICT), and electrical and electronic components—have continued to advance, electrical and electronic technology has established itself as a core sector underpinning South Korea’s industrial competitiveness. One of the leading educational institutions cultivating the talent that has supported this industrial development is the School of Electrical and Computer Engineering at Seoul National University. Are you interested in electrical engineering?

How was the School of Electrical and Computer Engineering established?

Just as the electrical and electronics industry plays a major role in the national economy, the School of Electrical and Computer Engineering at Seoul National University is also one of the largest schools within the university. The current School of Electrical and Information Engineering was formed through the integration of the Department of Electrical Engineering, the Department of Electronic Engineering, and the Department of Control and Instrumentation Engineering. Beginning in 1992, these three departments were consolidated into a group of departments covering the fields of electrical, electronic, and control and instrumentation engineering to recruit students, and in 1995, they officially adopted the name “School of Electrical Engineering.” Subsequently, in 2012, the school was renamed to its current name, the School of Electrical and Information Engineering.
Given the integration of diverse academic fields, the School of Electrical and Information Engineering conducts extensive education and research not only in electrical, electronic, and control engineering but also in closely related fields such as semiconductors, information and communications, computers, and electrical energy. Currently, the research and education areas of the School of Electrical and Information Engineering at Seoul National University can be broadly categorized into systems, devices, and computers, with various subfields—such as electrical energy systems, communications, control, semiconductor devices and integrated circuits, electronic physics and optoelectronics, and computers and ultra-high-density systems—interconnected with one another. The curriculum is designed so that even at the undergraduate level, students first gain a broad foundation across multiple fields and then, as they advance through their studies, can choose a major that aligns with their interests and career goals.

What Do You Learn in Electrical and Information Engineering?

Since the department was formed by integrating various disciplines, there are numerous subfields; however, based on the current curriculum, they can be broadly categorized into three main areas: systems, devices, and computers. First, the systems field can be further divided into subfields such as electrical power, communications, and control. Simply put, the communications field researches methods for efficiently and accurately transmitting the vast amounts of signals and information exchanged via mobile phones, computer networks, and other systems.
In the field of electrical energy, students analyze the characteristics of the power market and study the production, conversion, transmission, and efficient use of electrical energy. Since electrical energy serves as a vital foundation for modern industry and daily life, technologies for managing it stably and efficiently are of great importance. Research is also being conducted to ensure that new energy sources, such as renewable energy, can be effectively integrated into power systems. In the field of control, researchers study various control techniques to develop technologies that automatically operate and regulate robots, machinery, and systems. Robot-related technologies, such as robot soccer—which attracted widespread public interest in the past—are also closely related to these fields of control and robotics. The curriculum at Seoul National University’s School of Electrical and Computer Engineering offers major courses in various system fields, including electrical power, communications, and control.
Next, the device field covers a wide range of areas, including semiconductors and electronic physics. In the semiconductor field, research focuses on the principles, design, manufacturing, and application of various semiconductor devices and integrated circuits, including memory semiconductors such as DRAM. One of the key research topics is how to integrate more functions and electrical components into chips of limited size while simultaneously improving performance and efficiency. Home to world-class semiconductor companies such as Samsung Electronics and SK Hynix, South Korea boasts a large semiconductor industry where related research is actively conducted. Furthermore, electrical and information engineering is closely related to biomedical engineering, connecting to the electronic, signal, and control technologies necessary for the development and application of medical imaging devices—such as MRI—and various other medical devices. The field of electronic physics is closely linked to modern physics; it researches various technologies related to optoelectronics, plasma, displays, and semiconductors based on fundamental principles such as quantum mechanics. In particular, as semiconductor technology has already shifted to nano-scale microfabrication processes, the importance of electronic physics—which focuses on understanding the physical phenomena, materials, and device characteristics observed at the nanoscale—is growing even further.
Finally, there is the field of computer science. While it overlaps to some extent with the Department of Computer Science, the computer science program within the Department of Electrical and Information Engineering covers a broad range of topics—from computer software itself to the computing technologies necessary for controlling electrical and electronic systems and machinery, as well as operating various devices. Therefore, the program emphasizes not only learning programming languages but also understanding systems that integrate hardware and software and applying this knowledge to real-world industries. It can also be linked to artificial intelligence, data processing, embedded systems, intelligent systems, robotics, and various automation systems; students can also gain exposure to related fields—such as game development—through computer programming, graphics, and systems technology. Today, as computer technology is integrating not only with the electrical and electronics industries but also with various other sectors—including manufacturing, telecommunications, automotive, robotics, and artificial intelligence—the range of career paths where students can apply the knowledge and skills gained from majoring in computer science is expanding.

What opportunities are available to those who major in Electrical and Information Engineering?

Even with this broad overview of each field, Electrical and Information Engineering encompasses a wide variety of subfields, so delving deeper allows you to explore many more academic disciplines and technologies. The appeal of the Department of Electrical and Information Engineering lies in the fact that various academic disciplines are organically interconnected within a single department, enabling students to experience diverse fields during their undergraduate years and offering a wide range of career paths to choose from based on their aptitudes and interests. Furthermore, since electrical and information engineering is closely tied not only to the various products and services we use but also to diverse industries such as manufacturing, energy, telecommunications, automotive, robotics, healthcare, and artificial intelligence, there is a high likelihood that you will be able to apply your major-specific knowledge even if you choose a career path unrelated to your major after graduation.
The School of Electrical and Information Engineering at Seoul National University has structured its curriculum to provide a broad foundation in the fields of electrical, electronic, and control engineering, followed by the opportunity to select from a variety of specialized courses. Recently, the school has also been expanding its educational and research programs linked to future technologies such as artificial intelligence, AI semiconductors, and intelligent communications.
If you major in Electrical and Information Engineering—a field that can be applied to such a wide range of areas—during your undergraduate studies, you will be able to combine the knowledge and experience gained from your major with other fields to create new possibilities, no matter what career path you pursue after graduation. The academic journey is not easy, as you must earn a relatively large number of major credits compared to other departments and study a broad range of subjects, from foundational disciplines like mathematics and physics to specialized knowledge in the fields of electrical engineering, electronics, and control systems. However, as the saying goes, “No pain, no gain.” If you persistently study electrical and information engineering in college while exploring your areas of interest, you will develop not only specialized knowledge but also the ability to analyze problems and understand new technologies. Since electrical and information engineering is not a discipline limited to a single industry but rather a foundational field that connects various technologies and industries, it is a major that opens up a wide range of possibilities even for students who have not yet firmly decided on their future career path.
