Career Highlights: With four silver medals in hand, Joyce has had her fair share of success at the Olympics. All four medals have come in relays, and now she will be looking to win her first individual medal in the 50-meter freestyle in London. Joyce won silver in the 4x100 freestyle relay and the 4x100 medley relay at the 2004 and 2008 Games but has never finished higher than fifth place in the 50 freestyle. The former University of Georgia star was a four-time national champion in the 50 freestyle and 100 freestyle during her collegiate career, and she set the American record for the 50 freestyle in 2006. Joyce also set the record for the 50 at the Pan American Games in 2003, and her last victory in the 50 came at the 2010 CP National Championships. When Joyce isn't in the pool, she enjoys shopping and also is a vocalist and drummer for the ABSC Rock Band.
