Mouse models reveal how genome maintenance impacts aging and longevity. Studying these genetic pathways helps understand the molecular basis of human aging and cell viability.

Area of Science:

  • Gerontology
  • Molecular Biology
  • Genetics

Background:

  • Aging research heavily relies on model organisms like yeast, nematodes, and mice.
