Career
Joe competed in a breaststroke double at the 2000 Summer Olympics in Sydney. In the 100 m breaststroke, held on the first day of the Games, Joe challenged seven other swimmers in heat four, including two-time Olympians Valērijs Kalmikovs of Latvia and Arsenio López of Puerto Rico. He earned a fifth spot and forty-fifth overall by almost seven-tenths of a second (070) behind joint winners Kalmikovs and Lopez in 1:04.71, worthy enough for a personal best.
Three days later, in the 200 m breaststroke, Joe placed twenty-ninth on the morning prelims.
He set a new South Korean record of 2:19.16 to overhaul a 2:20 barrier and to touch the wall first in heat three.
