Key Interests

Small and large ruminant reproductive physiology, gamete physiology, in vitro fertilization, transgenic animal production, gene targeting, mammalian semen and embryo transfer and cryopreservation, cell modification, bioweapons and agroterrorism and the development and management of biosecurity facilities for animals used in research and commercial applications.

Current Research Interests

To develop  a panel of tests analyzing the motility, morphologic, biochemical and genomic characteristics of caprine sperm used for predicting future fertility in naïve males to enhance goat production systems, to design and implement experimentation to understand and overcome the problems of early regressing CLs in natural and artificial goat reproduction systems and to develop a core facility for the production of genetically modified goats as both animal models and bioreactors.
