Research

Our lab studies several different aspects of aging biology.  We mainly use the powerful genetic model C. elegans as a discovery tool for new longevity genes and perform functional analyses to elucidate the mechanistic basis of their longevity functions.

Chromatin & transcriptional regulation in development and longevity

  • How do changes in global chromatin landscape and specific gene expression impact the aging process and longevity?
  • What are the key chromatin and gene regulation factors that modulate aging and longevity?
  • How do mild stress early in life results in beneficial resilience later in life?

Fat metabolism, reproduction, and longevity

  • How do organisms coordinate resources between reproduction and somatic maintenance?
  • How do sterile mutants re-configure the excessive resources that normally are required for reproduction?
  • What are the molecular players involved in this energetic reconfiguration?

Mitochondria and Longevity

  • How do mild dysfunction of mitochondria impact physiology and longevity?
  • What are the molecular players that mediate the signaling communication between mitochondria in different tissues?
