Defining healthy aging

We age. Some of us age better than others. Some of us show prolonged health. Our research focuses on understanding the fundamental processes that define how we age. We use a combination of molecular biology, genetics, biochemistry, and genomics to define: what contributes to lifespan? What defines healthy aging (healthspan)? What dictates metabolic health? How does the environment contribute? What about nutrition/diet? Overall, we want to determine the critical pathways/genes that define health. 

Specific Interests

  1. In C. elegans, the insulin/IGF-1 signaling pathway plays a central role in regulating lifespan, fat storage, stress and development. What are all the genes involved? How is each specific phenotype modulated? Are they modulated together?
  2. How do multiple conserved signaling pathways couple to the insulin/IGF-1 pathway to regulate lifespan? Fat storage? Stress? Development?
  3. How does the forkhead transcription factor DAF-16 function as a central mediator in C. elegans?
