Noh won the
2010 Junior World Championships, and due to the format of the South Korean National Team selection rules, he was able to win a spot on the team with his speediness on the ice for the 2010-2011 season despite his inexperience compared to veterans of the sport. He quieted critics of his placement on the team by performing well at the
2011 Asian Winter Games, but struggled against experienced skaters at international events during the
2010–11 ISU Short Track Speed Skating World Cup, where technical aspects such as positioning skills are considered essential. He won the overall World Championship in his first season on the senior level. In the following week, Noh helped Korea to win 2011
World Team Championships (last one to be scheduled into foreseeable future) in
Warsaw, setting a new world record in 3000m in the process. He discovered a benign tumor in his left shoulder in September 2013 and upon further inspection, it was discovered that he had a five-inch malignant tumor in his shoulder. He delayed surgery to allow him to compete at the
2014 Winter Olympics in Sochi. He would have competed in the Olympics, but was ruled out due to a broken elbow. He died on 3 April 2016 from cancer. == Personal life ==
