Research Overview: Eggs can survive in a dormant state for many years. They then dramatically reawaken upon fertilization and give rise to a complex organism. How does this happen?  The Woodruff lab combines live-cell imaging, nano-rheology, and in vitro reconstiution to address how organelles assemble and disassemble following fertilization.  The lab also focuses on protein quality control and stability in oocytes. With this knowledge, we can hopefully better understand how cell division errors arise during cellular ageing and contribute to cancer and fertility decline during advanced materal age.


Research Interest

  • Biochemistry, cell biology, and synthetic biology
  • CRISPR/Cas9 modification of embryos
  • Material properties of organelles
  • Oocyte quality and age-related fertility problems
  • Regulation of centrosome size and number
