Erica Barnell, Geneoscopy

This week on Careers in Discovery, we’re joined by Erica Barnell, Chief Medical Officer and Co-founder of Geneoscopy. Erica shares how Geneoscopy is transforming gastrointestinal health with a platform that uses RNA biomarkers from stool samples to diagnose, monitor, and help prevent colorectal cancer and other GI diseases. She talks about the inspiration behind the company, building a patient-friendly alternative to colonoscopy, and why early detection is key to changing outcomes in colorectal cancer. We also dive into Erica’s journey from MD-PhD student to entrepreneur, the challenges of shifting from product development to commercialization, and how she navigates the balance of leadership, family, and growth in a dynamic start-up environment.
