Dr. Julia Vaizer will succeed Dr. Geoffrey Billows as the director of medical services for IndyCar and Indianapolis Motor Speedway (IMS). Vaizer becomes the first female medical chief in the sanctioning body’s and track’s history.

Vaizer, who has served as the assistant medical director for IndyCar and IMS since 2021, also served as acting medical director when Billows was on a short medical leave of absence earlier this spring. Billows will continue contributing to medical services part-time starting in 2023.

“Dr. Billows has been a friend, a mentor, a teacher and like family to me,” Vaizer said. “There are a lot of emotions of excitement for him to take a new stage in his life and spend more time with his family. It’s wonderful that he’s going to stay on as an INDYCAR physician.

Vaizer received her undergraduate degree in 2011 from the University of Florida and her medical degree in 2016 from the University of Central Florida. She completed her emergency residency training at Detroit Receiving Hospital in 2019 and completed a dual EMS/motorsports medicine fellowship at IU School of Medicine in 2021.
