We are currently looking for graduate students to work on the molecular mechanisms of gamete fusion and on the genetic control of early cell lineage specification in preimplantation embryos.

Lab news:

We will present preliminary data at the Gordon Research Conference (GRC) on Fertilization and Activation of Development. See preliminary program of the meeting here.

The program of the Gordon Research Seminar  on Fertilization and Activation of Development may be visualized here.

Basic research: We use mouse genetics to investigate the molecular mechanisms controlling fertilization (sperm-egg recognition and fusion) in mice and humans. Using genome editing technologies, we establish transgenic mouse lines that express mutant proteins in place of the endogenous mouse proteins. Using in vitro fertilization (IVF) techniques, we test the ability of transgenic gametes to interact for successful fertilization and embryo development.

Translational research: We work on developing novel assays to improve pregnancy outcome for fertility treatments.
