The laboratory research focuses on understanding the remarkable properties of the mammalian oocyte, which exists as a highly differentiated cell type endowed with the unique capacity for creating an embryonic genome from the two terminally differentiated gamete genomes, activating that embryonic genome, and regulating its function during much of the preimplantation period. The research seeks to understand these fundamental, life-generating processes at the molecular level, by employing a combination of microsurgery, quantitative gene expression analyses, microarray analyses, and structural studies.
