Brett Clothier is the Head of the Athletics Integrity Unit (AIU), the independent body that manages all integrity related issues for the sport of athletics globally. The AIU became operational in 2017 following changes to the World Athletics Constitution. These changes enshrined the operational independence of the AIU from the rest of World Athletics and put in place an independent Board to oversee its functions. Mr Clothier has worked in sport integrity for 20 years. Prior to becoming the inaugural Head of the AIU, Mr Clothier worked in Australia as Head of Competition Integrity for the Australian Football League (AFL) and Legal Counsel to the Integrity Services Department of Racing Victoria.
