Career
She represented South of Korea in two editions of the Olympic Games (1996 and 2000), and also earned bronze medals in the medley relay at the Asian Games (1994 and 1998). Lee made her Olympic debut at the 1996 Summer Olympics in Atlanta. At the 2000 Summer Olympics in Sydney, Lee drastically shortened her program on her second Olympic appearance, swimming only in two events.
On the first day of the Games, Lee placed thirty-fifth in the 100 m butterfly.
Swimming in heat three, she powered past the field with an early lead at the first turn, but faded down the stretch to a fourth-place time and a lifetime best of 1:02.22. Lee also teamed up with Shim Minister-Ji, Chang Hee-Jin, and Ku Hyo-Jin in the 4×100 m medley relay.
Swimming the butterfly leg in heat two, Lee recorded a split of 1:03.15, but the South Koreans rounded out a six-team field to last place and seventeenth overall in a final time of 4:16.93.
