Research Interests

Reproductive biology, gamete and embryo development, epigenetics, somatic cell nuclear transfer, embryonic stem cells, induced pluripotency.

Our long term research goal is to uncover the mechanisms of epigenetic remodeling orchestrated by the oocyte during early embryonic development and after somatic cell nuclear transfer. We use that knowledge to improve and develop methods of cellular reprogramming for the production of cloned animals for agricultural and biomedical uses, and to create autologous cells for transplantation therapies in animals and humans.
