Career Highlights: 2008 Bronze medalist at the Olympic Games in the 400m Hurdles; 2005 World Outdoor champion; 2003 USA Outdoor champion; 2005 USA Indoor 400m champion; 2002 U.S. junior champion; 2002 World Junior bronze medalist; 2002 World Junior 4x400 champion

Jackson's 2007 season was highlighted by wins at the Kansas Relays, Osaka GP, and at the Athens GP. In ending the 2007 season ranked #5 in the world, Jackson has been ranked in world's the top ten in the men's 400m hurdles by Track & Field News each year since 2003.  The dominant force in the men's 400m hurdles throughout the 2005 season, Jackson was motivated by his failure to make the 2004 Olympic team. His determination paid off.  Jackson used his tremendous finishing speed in capturing the gold medal at the World Outdoor Championships in Helsinki in a personal best time of 47.30 seconds. Jackson's victory was the first for an American in this event at a World Outdoor Championships since Derrick Adkins mined gold at Gothenburg in 1995 (47.98). With fellow American James Carter finishing second, it marked the first time Americans had finished 1-2 in the men's 400m hurdles since Rome in 1987 when National Track & Field Hall of Famer Edwin Moses won the gold and Danny Harris brought home the silver medal. Jackson and Carter's career best performances in Helsinki are even more impressive considering that the race was held during a torrential downpour in Helsinki. Their times were the second and third fastest in the world during the 2005 season. Jackson's 2005 season got off to a tremendous start with his performance at the USA Indoor Championships, where he won the 400m national title in 46.05 seconds. Jackson's only loss during the 2005 outdoor season came when he was the runner-up at the USA Outdoor Championships. His 12 worldwide wins in 2005 made him an easy choice for the coveted 400m hurdles world #1 ranking that year from Track & Field News. The newest phenom over the intermediate hurdles, Jackson has improved his personal best by more than 2 seconds since 2002. For the second season in a row, Jackson posted the second fastest time by an American with his monster (then) personal best of 47.86, which bettered his previous PR of 48.23 in winning at Madrid in 2003. The 2002 U.S. junior champion and World Junior bronze medalist, Jackson planned to be part of the University of South Carolina track powerhouse, but he instead competed on the circuit....In 2004 joined the St. Augustine's College roster... raised in Miami, he now lives and trains in Raleigh, N.C., where he is coached by 2004 Olympic Team Head Coach George Williams...daughter Shawnte was born May 2, 2005.
