She achieved her personal best throw of 20.04 m in May that year and managed fifth place at the 2007 World Championships in Athletics held in Osaka.
In November 2010 she announced her retirement from the sport through persistent elbow injury she had first sustained after a fall in training two years earlier.

She was selected to compete in the two-woman event at the FIBT World Championships 2012 alongside Sandra Kiriasis and won the silver medal, finishing a third of a second behind the winning Canadian team.
