Those positives come as no surprise given that Cullen has exceptional experience in the field of motorsport, previously working alongside seven-time Formula 1 world champion Lewis Hamilton during several of his championship-winning campaigns.
Speaking about the pair's relationship, Cullen has revealed that she hopes to be impacting Armstrong positively but stressed that their working partnership is still very much in its infancy.
"I hope so. I really hope so,” Cullen replied when asked by IndyCar if she thought she was making a difference to Armstrong's season.
“We’ve only seen working together maybe three months, so the way I coach is very much about getting to know them as a person and then helping facilitate how I can help them.
“So we’re probably still in the infancy stage, sort of navigating how that’s going to work in the future.”
Cullen's comments at the end suggest that she and Armstrong will continue to work together into the future, suggesting a long-term link-up.
Armstrong currently sits P14 in the 2024 IndyCar standings.
