Research Interests: 

  • Oocyte
  • Maturation
  • IVF
  • Phosphodiesterase
  • Gap junction communication
  • Spermatozoa
  • Cumulus


Summary of Results:

My lab is interested in cellular signaling. We are studying phosphodiesterases in oocyte physiology, especially during oocyte maturation. We have also developed a system to measure gap junction communication live between cumulus cells in 3D. We are also interested in the study of phosphodiesterases in sperm function. Thus, we are developing a new culture media to improve oocytes quality in order to improve blastocysts rates in vitro produced.
