Buisson represented France at the 2008 Summer Olympics in Beijing, where she successfully cleared a height of 4.15 metres in the women's pole vault, an event which was later dominated by world-record holder Yelena Isinbayeva of Russia. Buisson, however, failed to advance into the final, as she placed twenty-third overall in the qualifying rounds, tying her position with Iceland's Thórey Edda Elisdóttir.
