Medicine in Motorsports with Dr. Julia Vaizer

Jun 10, 2026 · 70 min

Description Katherine Legge is joined by Dr. Julia Vaizer, medical director for IndyCar and the Indianapolis Motor Speedway and the first female medical director in IndyCar history. Vaizer explains how early motorsports fandom and a MotoGP tragedy pushed her to merge racing with emergency medicine, leading her to become the first fellow in the Motorsports Medicine Fellowship and later IndyCar leadership. They discuss how IndyCar medical teams coordinate with other series and specialists, research projects like safest driver extrication and analyzing IMS patient data, and what race day at the Indy 500 looks like.
