The patient who needs immediate assistance should not communicate directly with the researcher. Instead, they should call the doctor’s office or take other appropriate measures, such as going to the nearest emergency service.

Research interests

Research in our laboratory is aimed at understanding how healthy eggs and embryos are made, and we are particularly focusing on how and why defects in chromosome segregation can cause infertility.

We specialize in the use of cutting edge microscopy techniques to analyze egg and embryo function ex-vivo. We have important collaborators in Montreal and elsewhere, and work closely with the CHUM Clinique de Procreation Assistée.

Ongoing projects in the lab include:

  • Analysis of spindle microtubule dynamics in oocytes.
  • Evaluation of the changes in spindle function that occur with maternal age, and how this causes chromosome segregation error.
  • Analysis of the mechanism of chromosome segregation in embryos, and the causes of segregation errors.
  • Analysis of apoptotic pathways in oocytes and embryos.
