I graduated from the Korea Military Academy in 1983 with a bachelor's degree in science, and was commissioned as a First Lieutenant of the Korean Army. I served as a platoon leader in the 17th Infantry Division and the Korea/US Joint Armed Forces. Upon completing intensive training in computer programming at the Korean Army General Management School, I became a computer program officer.
The Army Scholarship for Studying Abroad opened a door for me to study in the United States, and I completed my M.S. and Ph.D. in computer science at the University of Missouri-Kansas City in May 1990 and December 1993, respectively. My study focused on transferring files in a heterogeneous computer environment, which can really be seen now in the Internet world. My assignment was to renovate the army's computer networking systems by incorporating emerging Internet technology.
I began my teaching career in 1995 at the Korea Military Academy and the Korea National Defense University, where I taught for 12 years. While there, I regularly taught microcomputer applications, computer networks, mobile communications, computer architecture, and C/C++. I received several research grants to study the next generation architectural design of Command Control Communication Computer Intelligence (C4I) Systems.
In 2007 I retired from the Korean Army as a lieutenant colonel and associate professor of computer and information science, and immigrated to the United States. Since the fall of 2008, I have been an assistant professor of computer science at JCC. I routinely teach courses about Python, Java, HTML/CSS, PHP, computer networks, network administration, and data structures.
I am originally from Hampyung, a small town in the South Chon Province of Korea, where my siblings still live. My immediate family has migrated to Western New York with me, and we continue to enjoy exploring this area.
