I was born in Seoul, Korea (South) in 1971. Before I came to US for my graduate study I spent 25 years of my life there. I did my Master of Science in Computer Science at the Syracuse University. After one year Ph.D., I moved down to sunny Florida State University at Tallahassee, FL from snowy Syracuse, NY. I usually spend my extra time playing tennis and golf if the weather is fine. If it is hot or raining (FL) / cold or snowing (NY) , I will enjoy myself with movies and music.
