College of Science and Technology


Exploration, leading the science technology era


The College of science and technology pursues a scholarly understanding and application of the natural phenomena in all the realms of nature: the universe, earth, and all living things as subjects of exploration. This College is a place to research scholarly important discoveries that illuminate the relationships between man and nature. Through such exploration, we can find new tools for the development of scientific technologies. The College of science and technology, equipped with outstanding teaching staff and the latest research facilities, has carried on bilateral education between the scientific theories and their applications through lectures and experiments. It trains scientific minds that will contribute to advanced science and technology in the future.

Educational Objectives

As with the study of the behavior of natural phenomena, modern science investigates natural objects like the universe, the earth, and life. Through these investigations, modern science illustrates the relationship between nature and mankind, and provides new ways to develop scientific technology.


On the basis of these facts, it is desirable that every field of modern science should be studied and developed together rather than independently. Currently, there is a general trend of interrelated studies being actively carried our in the dields of science and Technology.

Established in 1983, the College of Science and Technology (CST) has grown to become one of the leading institutions in the field of applied science in Korea. CST pursues not only a scholarly understanding of natural phenomena in all realms of nature but also practical application of science in human life. Now CST is comprised of five departments with 50 faculty members and about one thousand students are in the undergraduate and graduate programs. CST trains scientific minds that will contribute to the advances in 21st century technology.


In the Applied Mathematics Department, based on three traditional fields, for instance, Mathematical Analysis, Algebra, and Geometry, there are three majors- Scientific Computing, Analytical Science, and Applied Statistics. Eight faculty members are actively working and researching on their areas of interest pursuing the practical principle of academy.


Department of Applied Physics is devoted to the 21st century’s cutting-edge semiconductor technology and science. More specifically, the field named as nano-information-device physics includes fabrication of nano-scale semiconductor structures, measurements of physical properties of those nano-devices and the understanding of them on the basis of quantum physics. The education program covers the state of the art fields in which major Korean semiconductor industries are interested.


Teaching in Applied Chemistry major is centered around four subdivisions of physical, organic, inorganic and analytical chemistry with the equal emphasis on the theory and experiments. The 12 faculty members, along with more than 50 graduate students and researchers, carry out active research in areas that encompass fundamental sciences and cutting-edge industry, namely bionano fusion technology, nano materials and devices, medicinal chemistry and fine chemical industry.


The Department of Environmental Marine Sciences researches the underwater acoustics and physical oceanography elucidating oceanographic properties. It also studies exploration on the marine geo-resources and geophysical environments, and conservation of marine biodiversity and restoration of coastal marine environments. Another research topic is biogeochemical and microbiological studies on the major elements.


Life Science is the field that aims to unveil the secrets of life. The department seeks to gain basic and advanced knowledge about life and to solve medical, environmental, and developmental problems. Life Science requires the understanding of several levels of organization, including bio-macromolecules such as proteins, nucleic acids, lipids, and carbohydrates, complex cellular processes such as metabolism and signal transduction, and the behavior of whole cells and organisms.

Q. Please introduce yourself and the College of Science and Technology to our readers.
A. The study of science and technology is based on understanding an object or natural phenomenon, and applying that knowledge to human life. The College of Science and Technology studies the mutual relationship between basic science and applied science. In doing so, we have made many accomplishments in the field of technology so far. Our goal is to foster scientific geniuses with a magnificent understanding in modern science. As to whom I am, I am a professor in the major of Applied Physics, and have done some research on thin film used for semiconductors and solar batteries. Currently, I am doing research on the future semiconductor production process.


Q. Would you briefly introduce each of the majors in the College of Science and Technology?
A. The College of Science and Technology was founded in 1983 and is divided into two divisions: the Division of Science and Technology, and the Division of Molecular & Life Science. The Division of Science and Technology consists of four majors: the Major of Applied Mathematics, Major of Applied Physics, Major of Applied Chemistry, and Major of Environmental Marine Sciences. All the majors within the college are based on applied studies. Although it has only been 25 years since the first students graduated from the college, we assume that there are over 150 students who received a doctor’s degree in and out of the country.


Q. How many professors and students are there in the college?
A. There are a total 800 undergraduate students, two of whom are international students. We also have 120 post graduate students, ten of whom are international students. There are 49 full-time professors and one foreign professor.


Q. Does the college have its own personality at HYU?
A. ERICA is an organization which conducts research on basic science, and applies the obtained knowledge to applied sciences. Focusing on practical studies is the academic tradition of HYU, and I guess you can say that the College of Science and Technology is in the core of that tradition.


Q. What are some special achievements that helped to build the reputation of the college?
A. Firstly, there is the annual Applied Science Technology Competition in the college where nearly 20 teams participate to compete against each other with their outcomes of academic research. Many of these outcomes are sensational enough to be published in academic journals. Secondly, there are many companies based on Applied Science that the professors and graduates established. To name a few, there are ‘Genocheck’, ‘SJbiomed’, and 'Nano-View’. Lastly, the Division of Molecular & Life Science has been chosen as the SRC (Science Research Center) in 2011, after going through fierce competition.


Q. What is the futuristic vision of the college?
A. Globalization, unforeseeable future, and rapidly progressing technology are the key terms of today’s society. I believe that practical education with a strong foundation on basic science is one of the best ways to prepare for the marvelous future. The College of Science and Technology, as a global college, will pursue in practical science education and applied research to become the leader of tomorrow.
