Research Interests

  • The study of aging and stress resistance using the mouse and the nematode worm (Caenorhabditis elegans) as models.
  • The nematode is an excellent system for identifying new longevity and stress resistant genes.
  • The mouse studies focus on identifying genes responsible for stress resistance using a novel stem cell approach.
  • See our detailed IBG research page for the most up-to-date information.

Current Worm Research Projects

  • Health Span and Life Span - Examination of the relationship between health span and functional aging versus life span.
  • Stress Resistance and Life Span - Examination of the relations between life span and stress resistance, using comparative studies of stress resistance versus longevity, stress reporter lines, and forward genetic screens for stress-resistant mutants.

Current Mouse Research Projects

  • Identification of genes influencing stress resistance in the Mouse.
  • Identification of disease resistant loci using transposon induced mutant stem cells.
