Our laboratory is interested in improving the reproductive efficiency of domestic animals and primates through gamete research. Specifically, developing short and long term storage systems for preimplantation embryos by evaluating metabolic parameters and substrate utilization. In vitro fertilization and new methods of evaluating male fertility by direct sperm-oocyte interaction are currently active areas of interest. The physiochemical properties of zona pellucida and its role in development continues to be of interest.
Experiments are in progress to elucidate the mechanisms of early embryonic death.
Evidence has been obtained suggesting that these events may be occurring much earlier in development than previously realized.
