Hi. I have moved to a faculty position in Chungnam National University since March 2001
and the present page may be out of date
(visit new homepage).
I have my educational background in astronomy in general. I got a PhD degree at Department of Astronomy in Seoul National University, and am now working for Big Bear Solar Observatory as a research scientist. I have been studying various kinds of magnetic activities in the solar outer atmosphere with the help of others' works ( ADS, ApJ, A&A, Solar Physics, JGR, and so on) and by analyzing new data obtained by space-borne observations ( Yohkoh, SOHO, TRACE , GOES and HESSI) as well as by ground-based observations (BBSO, NSO and MSO).
