In 2000, Lang/Tchernyshev moved to Hackensack, New Jersey to train with Alexander Zhulin, who coached them until the end of the 2001–02 season. They missed their 2001 Grand Prix events because Tchernyshev had shin splits. Returning to competition, they won their fourth national title at the 2002 U.S. Championships and then won their second Four Continents title. They placed eleventh at the 2002 Winter Olympics and ninth at the 2002 World Championships.
