Short Description UCL professor challenging programmed‑aging dogma in C. elegans.
Description Evolutionary biologist David Gems studies lifespan pathways in nematodes, questioning theories that aging is programmed versus stochastic damage. His lab showed that insulin/IGF signaling affects worm aging via pheromone perception and metabolic reprogramming. Gems is a vocal critic of hype, pushing for evolutionary rigor in longevity claims and advising UK regulators.
