What if the bacteria living in our gut could help determine how well a cancer treatment works?

In this episode of The Curious Mindset, we sit down with 2026 Early Career Investigator Dr. Arielle Elkrief to explore her research into the gut microbiome and cancer immunotherapy. From uncovering how antibiotic exposure can affect treatment outcomes to investigating fecal microbiota transplantation, Arielle’s work is helping reveal new ways to improve how patients respond to cancer treatment.

We also dive into the realities of scientific discovery—from learning directly from patients and navigating uncertainty to understanding how a disappointing result can lead to a groundbreaking discovery.

Beyond the lab, Arielle shares her advice for young scientists, her dream of becoming an astronaut, her love of running and Taylor Swift, and the snack that sparked some serious debate.
