Date Posted: Friday, November 07, 2025
Heidi Tissenbaum, PhD, recently appeared on Longevity Roadmap, a podcast hosted by Dr. Buck Joffrey, MD, that features conversations with leading scientists in the field of aging research.
In the episode, “Molecular Secrets of Aging Told Through Worms,” Dr. Tissenbaum discusses why the tiny nematode Caenorhabditis elegans is such a powerful model organism for studying longevity, and how seminal research in C. elegans uncovered an evolutionarily conserved biological pathway—the insulin/IGF-1 signaling pathway—that ultimately led to the identification of a key gene associated with human longevity. She also emphasizes the importance of measuring healthspan (healthy aging), not just lifespan, and shares her perspective as a basic scientist on the future of aging research.
