An Olympic and World Championships gold medalist and a six-time NCAA champion, USC graduate Rebecca Soni is in her third year as a volunteer assistant swimming coach at USC.
The top breaststroker in the world, Soni swept the 100m and 200m breast at the 2011 World Championships and won another gold in the 400m medley relay (with an American record) as well as a bronze in the 50m breast.
She won three gold medals (50m, 100m and 200m breast) at the 2010 Short Course World Championships (she also won a silver in the 400m medley relay) as well as titles in the 100m and 200m breast (lc) at the 2010 Pan Pacific Championships. Soni, who also won those events at the 2010 U.S. Nationals, was named USA Swimming's Female Athlete of the Year for 2010 for the second year in a row.
Soni was an 11-time All-American as a Trojan between 2006-09 and became the first woman to win the NCAA title in the 200y breast four consecutive years. She also won the NCAA 100y breast crowns in 2008 and 2009 and won a combined six Pac-10 titles.
Soni became an international swimming star at the 2008 Olympics when she won the gold medal in the 200-meter breast in a then-world record time (2:20.22). Her gold came just days after winning a silver medal in the 100m breast (1:06.73) and was soon followed by a silver on the U.S. 4x100m medley relay.
She solidified her standing as one of the top breaststrokers ever when she followed up her Olympic success with a gold medal in the 100m breast at the 2009 World Championships and a silver in the 50m breast. She also won breaststroke titles in the 100m and 200m at the U.S. World Championships Trials and at the U.S. Spring Nationals. Soni, who won her fifth and sixth NCAA and Pac-10 titles in 2009, was voted the 2009 U.S. Female Swimmer of the Year. She was also a 2009 Sullivan Award finalist.
One of USC's top student-athletes, Soni graduated from USC in 2009 with a degree in communications. She also earned Pac-10 All-Academic honorable mention honors for the second year in a row.
Soni is the American record holder in the 100m breast and the 400m medley relay and is the former world record holder in the 50m, 100m and 200m breast. She also holds the American, NCAA and Pac-10 records in the 200y breast, NCAA and Pac-10 records in the 100y breast and USC records in the 100 (yards, lcm) and 200 breast (yards, lcm, scm) as well as the 200y and 400y medley relays.
In 2008, in addition to her Olympic success, Soni won the 200m breast title at the U.S. Olympic Trials and won both the 100y and 200y breaststroke at the 2008 NCAA Championships, the first time she had swept both NCAA races. Her title in the 100y was USC's first in the event. USC's first swimmer to win two NCAA titles in the same season since Kaitlin Sandeno in 2004, Soni also earned All-American honors as part of USC's 400y medley relay. She did all of this less than two years after undergoing surgery to correct a rapid heartbeat condition. Like she did at the NCAAs, Soni won both the 100y and 200y breast at the 2008 Pac-10s.
Soni underwent minor heart surgery in the summer prior to the 2006-07 season which limited her training, but she still put together a strong sophomore campaign. She successfully defended her NCAA Championships crown in the 200y breast and reached the final of the 100y breast for the second year in a row. At the 2007 Pac-10s, Soni was second in the 200y breast (the only time she did not win a postseason 200y breast) and fourth in the 100y breast. At the U.S. vs. Australia Duel in the Pool in April, Soni was second in the breast and third in the 100m breast. At the 2007 U.S. Summer Nationals, Soni won national titles in the 100m and 200m breast, the second and third of her career. At the Japan International, the final major international meet of the 2007 season, Soni posted a pair of seconds in the 100m and 200m breast.
Soni put together the top season for a Trojan breaststroker in a decade as a 2006 freshman, winning an NCAA title in the 200y breast and capturing Pac-10 crowns in the 100y and 200y breast. She was a three-time All-American at the NCAA Championships, winning the 200y breast, taking second in the 100y breast and helping USC to second in the 400y medley relay in a school record 3:33.97. Soni was unbeaten in the 200y breast on the season. In addition to posting USC's fastest breaststroke times, she also posted USC's top times in the 200y IM and 400y IM. Despite having minor heart surgery during the summer, Soni still raced at the 2006 U.S. Summer Nationals, where she was 10th in both the 100m and 200m breast.
Soni was the 2005 U.S. national champion in the 200m breast after her final year competing at West Windsor-Plainsboro North in Plainsboro, N.J. The New Jersey state record holder in the 100y and 200y breast, Soni was ranked among the top 25 in the world in the 100m and 200m breaststroke throughout the 2005 season. She won a pair of silver medals at the 2005 U.S. World University Games, taking second in both the 100m and 200m breast and seventh in the 50m breast. She made the WUG team after placing third in third in the 200y breast and fourth in the 100y breast at the 2005 U.S. World Championships Trials. She was a 2004 Olympic Trials semifinalist in the 200m breaststroke and was second in the event at the 2004 U.S. Summer Nationals. She was also a two-time finalist at the 2003 Summer Nationals.
