This episode teaches that innovation is born at the intersection of curiosity and persistence. Dr. Gudrun Stengel, co-founder and CEO of Alida Biosciences, reveals how her startup is transforming the landscape of RNA research through a novel technology called proximity barcoding. Dr. Stengel’s story exemplifies the power of entrepreneurial spirit in driving scientific discovery, offering a glimpse into how one idea can reshape an entire field.

At Alida Biosciences, Dr. Stengel and her team are pioneering new tools for detecting RNA modifications, a largely unexplored realm of epigenetics. Using their proximity barcoding platform, researchers can read multiple RNA modifications simultaneously, uncovering potential biomarkers and therapeutic targets for diseases like cancer, Alzheimer’s, and diabetes. This technology bridges a critical gap in multiomics, allowing scientists to dive deeper into how epigenetic changes influence gene expression and cellular behavior.

Beyond the lab, Dr. Stengel shares her experience as a first-time founder, balancing scientific rigor with startup life. From managing a team to fundraising, her journey underscores the importance of resilience, optimism, and maintaining a long-term vision. She also offers valuable advice for budding scientists, encouraging them to embrace challenges and remain persistent in the face of setbacks.
